▼ Controlling thermal
power systems increases the overall
system efficiency and satisfies the desired requirements. In such a large
system, fuel reduction of even a small percentage leads to large energy saving. Hence,
power systems are gaining significant attention from engineers and scientists.
In this thesis, the uncontrolled
power system for single
area, two
area, and three
area is modelled using state space representation. Frequency deviation is simulated using MATLAB and SIMULINK. PID control is added to the
system to analyze the effect of conventional control on
system output response. Adaptive fuzzy logic control is added to the uncontrolled
system using MATLAB Fuzzy Inference
System and its effect on the
system output response is measured in terms of overshoot/undershoot percentage, settling time, and steady state frequency error. Effect of adaptive fuzzy logic control is analyzed on single
area, two
area, and three
area power system. Tie-line
power exchange among areas is investigated before and after implementation of PID and adaptive fuzzy logic control.
For the purpose of comparison in this thesis, a conventional PID control and an adaptive fuzzy logic control is applied to two different thermal
power systems. The simulations demonstrate that adaptive fuzzy logic control is proved to be more efficient and reliable than conventional PID control in
power system control problem.

▼ This thesis designs and implements two parts of Graphical User Interface(GUI) with
multi-thread based on Microsoft Visual Studio 2015 development platform and Visual C# programming language, real-time remote monitoring
system and big data analysis
system. In the real-time remote monitoring
system, we use asynchronous serial communication as a connection between computer and microcontroller unit which is designed for the process and packet, transforming the original data information into chart and data representation that is to be synchronized to TCP/IP communication and database. In order to evaluate the effect from control parameter and adjust the state to the wind turbine
system, we use Microsoft SQL Server database
system as experiment data saving, which is observing the operation and the state of the data in the stand-alone excited synchronous wind
power system in big data analysis
system.
This thesis uses permanent-magnet motor driver
system which is developed by the AC/DC motor control laboratory to replace servo motor, Mitsubishi-J4, in the stand-alone excited synchronous wind
power system. In order to give a command to the
system and get information from it, we use Controller
Area Network(CAN) as a connection between permanent-magnet motor driver
system and stand-alone excited synchronous wind
power system. Then we use the High Speed CAN to achieve better reliability and lower cost. Moreover, we can easily connect with other object and sensor to CAN in the stand-alone excited synchronous wind
power system.

▼ Currently, major
power systems almost invariably operate under interconnected
conditions to transfer
power in a stable and reliable manner.
Multi-
area reliability
evaluation has thus become an invaluable tool in the planning and operation of such
systems.
Multi -
area reliability evaluation is typically done by considering equivalent
tie lines between different areas in an integrated
power system. It gives approximate
results for the reliability indices of a
power system as it models each of the areas as a
single node to which are connected the entire
area generation and loads. The intratransmission
lines are only indirectly modeled during the calculation of equivalent tie
lines' capacities. This method is very widely used in the
power industry, but the
influence of the various approximations and assumptions, which are incorporated in this
method, on reliability calculations has not been explored.
The objective of the research work presented in this thesis is the development of
a new method called Composite
system based
multi -
area reliability model, which does
multi -
area reliability evaluation considering the whole composite
system. It models the
transmission
system in detail and also takes into account the loss sharing policy within an
area and no - load loss sharing policy among the areas. The proposed method is
applied to standard IEEE 24 bus Reliability Test
System (RTS) and the traditional
equivalent tie-line method is applied to the
multi-
area configuration of the same test
system. The results obtained by both the methods are analyzed and compared. It is found
that the traditional model, although having some advantages, may not give accurate
results.

▼ Electrical energy is one of the most common forms of energy these days. Consequently, electric
power system is an indispensable part of any society. However, due to the deregulation of electricity markets and the growth in the share of
power generation by uncontrollable renewable energies such as wind and solar,
power system simulations are more challenging than earlier. Thus, new techniques for simplifying these simulations are needed. One important example of such simplification techniques is the
power system reduction.
Power system reduction can be used at least for four different purposes: a) Simplifying the
power system simulations, b) Reducing the computational complexity, c) Compensating the data unavailability, and d) Reducing the existing uncertainty. Due to such reasons,
power system reduction is an important and necessary
subject, but a challenging task to do.
Power system reduction is even more essential when
system operators are facing very large-scale
power systems and when the renewable energy resources like hydro, wind, and solar have a high share in
power generation. This thesis focuses on the topic of large-scale
power system reduction with high penetration of renewable energy resources and tries to pursue the following goals: The thesis first reviews the different methods which can be used for simplifying the
power system studies, including the
power system reduction. A comparison among three important simplification techniques is also performed to reveal which simplification results in less error and more simulation time decrement. Secondly, different steps and methods for
power system reduction, including network aggregation and generation aggregation, are introduced, described and discussed. Some improvements regarding the
subject of
power system reduction, i.e. on both network aggregation and generation aggregation, are developed. Finally,
power system reduction is applied to some
power system problems and the results of these applications are evaluated. A general conclusion is that using
power system simplification techniques and specially the
system reduction can provides many important advantages in studying large-scale
power systems with high share of renewable energy generations. In most of applications, not only the
power system reduction highly reduces the complexity of the
power system study under consideration, but it also results in small errors. Therefore, it can be used as an efficient method for dealing with current bulk
power systems with huge amounts of renewable and distributed generations.

▼ Wide area monitoring system (WAMS), as an application of situation awareness, provides essential information for power system monitoring, planning, operation, and control. To fully utilize WAMS in smart grid, it is important to investigate and improve its performance, and develop advanced applications based on the data from WAMS. In this dissertation, the work on improving the WAMS performance and developing advanced applications are introduced.To improve the performance of WAMS, the work includes investigation of the impacts of measurement error and the requirements of system based on WAMS, and the solutions. PMU is one of the main sensors for WAMS. The phasor and frequency estimation algorithms implemented highly influence the performance of PMUs, and therefore the WAMS. The algorithms of PMUs are reviewed in Chapter 2. To understand how the errors impact WAMS application, different applications are investigated in Chapter 3, and their requirements of accuracy are given. In chapter 4, the error model of PMUs are developed, regarding different parameters of input signals and PMU operation conditions. The factors influence of accuracy of PMUs are analyzed in Chapter 5, including both internal and external error sources. Specifically, the impacts of increase renewables are analyzed. Based on the analysis above, a novel PMU is developed in Chapter 6, including algorithm and realization. This PMU is able to provide high accurate and fast responding measurements during both steady and dynamic state. It is potential to improve the performance of WAMS. To improve the interoperability, the C37.118.2 based data communication protocol is curtailed and realized for single-phase distribution-level PMUs, which are presented in Chapter 7.WAMS-based applications are developed and introduced in Chapter 8-10. The first application is to use the spatial and temporal characterization of power system frequency for data authentication, location estimation and the detection of cyber-attack. The second application is to detect the GPS attack on the synchronized time interval. The third application is to detect the geomagnetically induced currents (GIC) resulted from GMD and EMP-E3. These applications, benefited from the novel PMU proposed in Chapter 6, can be used to enhance the security and robust of power system.

▼ Coalition formation is a key cooperative behavior of a
system of multiple autonomous agents. When the capabilities of
individual agents are not su fficient for the improvement of
well-being of the individual agents or of the entire
system, the
agents can bene t by joining forces together in coalitions.
Coalition formation is a technique for finding coalitions that are
best fi tted to achieve individual or group goals. This is a
computationally expensive task because often all combinations of
agents have to be considered in order to find the best assignments
of agents to coalitions. Previous research has therefore focused
mainly on small-scale or otherwise restricted systems. In this
thesis we study coalition formation in large-scale
multi-agent
systems. We propose an approach for coalition formation based on
multi-agent simulation. This approach allows us to find coalitions
in systems with thousands of agents. It also lets us modify
behaviors of individual agents in order to better match a specific
coalition formation application. Finally, our approach can consider
both social welfare of the
multi-agent
system and well-being of
individual self-interested agents.
Power distribution systems are
used to deliver electric energy from the transmission
system to
households. Because of the increased availability of distributed
generation using renewable resources, push towards higher use of
renewable energy, and increasing use of electric vehicles, the
power distribution systems are undergoing significant changes
towards active consumers who participate in both supply and demand
sides of the electricity market and the underlying
power grid. In
this thesis we address the ongoing change in
power distribution
systems by studying how the use of renewable energy can be
increased with the help of coalition formation. We propose an
approach that lets renewable generators, which face uncertainty in
generation prediction, to form coalitions with energy stores, which
on the other hand are always able to deliver the committed
power.
These coalitions help decrease the uncertainty of the
power
generation of renewable generators, consequently allowing the
generators to increase their use of renewable energy while at the
same time increasing their pro fits. Energy stores also bene t from
participating in coalitions with renewable generators, because they
receive payments from the generators for the availability of their
power at specific time slots. We first study this problem assuming
no physical constraints of the underlying
power grid. Then we
analyze how coalition formation of renewable generators and energy
stores in a
power grid with physical constraints impacts the state
of the grid, and we propose agent behavior that leads to increase
in use of renewable energy as well as maintains stability of the
grid.

▼ With the increase in size and complexity of Power
Systems, the problems associated with long distance AC bulk power
transmission, like reactive power support, system stability etc
have also increased. A search for more efficient mode of
transmission has led to the development of DC transmission. An HVDC
transmission link is highly controllable and hence its effective
use depends on the appropriate utilization of this controllability
to ensure desired performance of the power system. In this thesis,
investigations are carried out on the improvement of power system
stability by employing auxiliary controls for controlling HVDC
power flow. AC/DC load flow using eliminated variable method is
utilized in the transient stability analysis. Transient stability
analysis is carried out on single machine infinite bus system and
multi machine system, using different control signals derived from
the AC system and employing different types of controllers. The
best possible combination of the different control signals, which
stabilizes the system, is found out and its effectiveness is
verified. Apart from the conventional, fuzzy logic based variable
gain controller is also developed to further improve the stability
of the power system. A new fuzzy logic based DC modulation
controller is also developed for a multi machine system taking the
average error and its derivative as inputs. The stability
performance of the power system with such fuzzy logic controller is
presented.

▼ Contemporary power networks are gradually expanding incorporating new sources of electrical energy and power electronic based devices. The major stability issue in large interconnected power systems is the lightly damped interarea oscillations. In the light of growth of their incidents there are increased concerns about the effectiveness of current control devices and control systems in maintaining power system stability. This thesis presents a Wide Area Measurement System (WAMS) based control scheme to enhance power system stability. The control scheme has a hierarchical (two-level) structure comprising a Supplementary Wide-Area Controller (SWAC) built on top of existing Power System Stabilisers (PSSs). The SWAC's focus is on stabilising the critical interarea oscillations in the system while leaving local modes to be controlled entirely by local PSSs. Both control systems in the two levels work together to maintain system stability. The scheme relies on synchronised measurements supplied by Phasor Measurement Units (PMUs) through the WAMS and the only cost requirement is for the communication infrastructure which is already available, or it will be in the near future. A novel linear quadratic Gaussian (LQG) control design approach which targets the interarea modes directly is introduced in this thesis. Its features are demonstrated through a comparison with the conventional method commonly used in power system damping applications. The modal LQG approach offers simplicity and flexibility when targeting multiple interarea modes without affecting local modes and local controllers, thus making it highly suitable to hierarchical WAMS based control schemes. Applicability of the approach to large power systems is demonstrated using different scenarios of model order reduction. The design approach incorporates time delays experienced in the transmission of the SWAC's input/output signals. Issues regarding values of time delays and required level of detail in modelling time delays are thoroughly discussed. Three methods for selection of input/output signals for WAMS based damping controllers are presented and reviewed. The first method uses modal observability/controllability factors. The second method is based on the Sequential Orthogonalisation (SO) algorithm, a tool for the optimal placement of measurement devices. Its application is extended and generalised in this thesis to handle the problem of input/output signal selection. The third method combines clustering techniques and modal factor analysis. The clustering method uses advanced Principal Component Analysis (PCA) where its draw backs and limitations, in the context of power system dynamics' applications, are overcome. The methods for signal selection are compared using both small signal and transient stability analysis to determine the best optimal set of signals. Enhancement of power system stability is demonstrated by applying the proposed WAMS based control scheme on the New England test system. The multi-input multi-output (MIMO) WAMS based damping…

▼ This thesis investigates the effects of High Voltage Direct Current (HVDC) lines andmulti-terminal grids on power system small-disturbance stability in the presence ofoperational uncertainties. The main outcome of this research is the comprehensiveprobabilistic assessment of the stability improvements that can be achieved through theuse of supplementary damping control applied to HVDC systems.Power systems are increasingly operated closer to stability boundaries in order toimprove their efficiency and economic value whilst a growing number of conventionalcontrolled power plants are being replaced by stochastic renewable generation sources.The resulting uncertainty in conditions can increase the risk of operational stabilityconcerns and should be thoroughly evaluated. There is also a growing necessity toexplore the potential improvements and challenges created by the introduction of newequipment, such as HVDC systems. In recent years, HVDC systems have become moreeconomically competitive and increasingly flexible, resulting in a proliferation ofprojects. Although primarily installed for power transmission purposes, their flexibilityand controllability can provide further benefits, such as the damping of persistentoscillations in the interconnected networks.This work contributes to a number of areas of power systems research, specificallysurrounding the effects of HVDC systems on the small-disturbance stability oftransmission networks. The application and comprehensive assessment of a Wide AreaMeasurement System (WAMS) based damping controller with various HVDC systemsis completed. The studies performed on a variety of HVDC technology types andconfigurations – as well as differing AC test networks – demonstrate the potential forHVDC-based Power Oscillation Damping (POD). These studies include examinationsof previously unexplored topics such as the effects of available modulation capacity andthe use of voltage source converter multi-terminal HVDC grids for POD. Followingthese investigations, a methodology to probabilistically test the robustness of HVDC based damping controllers is developed. This methodology makes use of classificationtechniques to identify possible mitigation options for power system operators whenperformance is sub-optimal. To reduce the high computational burden associated withthis methodology, the Probabilistic Collocation Method (PCM) is developed in order toefficiently identify the statistical distributions of critical system modes in the presenceof uncertainties. Methods of uncertain parameter reduction based on eigenvaluesensitivity are developed and demonstrated to ensure accurate results when the PCM isused with large test systems. Finally, the concepts and techniques introduced within thethesis are combined to probabilistically design a WAMS-based POD controller morerobust to operational uncertainties. The use of the PCM during the probabilistic designresults in rapid and robust synthesis of HVDC-based POD controllers.

▼ A
power system with multiple interconnected areas needs to be operated coordinately
for the purposes of the
system reliability and economic operation, although
each
area has its own ISO under the market environment. In consolidation of different
areas under a common grid coordinator, analysis of a
power system becomes more
computationally demanding. Furthermore, the analysis becomes more challenging
because each
area cannot obtain the network operating or economic data of other
areas.
This dissertation investigates decomposition algorithms for
multi-
area power system
transfer capability analysis and economic dispatch analysis. All of the proposed
algorithms assume that areas do not share their network operating and economic
information among themselves, while they are willing to cooperate via a central coordinator
for
system wide analyses.
The first proposed algorithm is based on
power transfer distribution factors
(PTDFs). A quadratic approximation, developed for the nonlinear PTDFs, is used to
update tie-line
power flows calculated by Repeated
Power Flow (RPF). These tie-line
power flows are then treated as injections in the TTC calculation of each
area, as
the central entity coordinates these results to determine the final
system-wide TTC
value.
The second proposed algorithm is based on REI-type network equivalents. It uses
the Continuation
Power Flow (CPF) as the computational tool and, thus, the problem of voltage stability is considered in TTC studies. Each
area uses REI equivalents of
external areas to compute its TTC via the CPF. The choice and updating procedure
for the continuation parameter employed by the CPF is implemented in a distributed
but coordinated manner.
The third proposed algorithm is based on inexact penalty functions. The traditional
OPF is treated as the optimization problems with global variables. Quadratic
penalty functions are used to relax the compatible constraints between the global
variables and the local variables. The solution is proposed to be implemented by
using a two-level computational architecture.
All of the proposed algorithms are verified by numerical comparisons between the
integrated and proposed decomposition algorithms. The proposed algorithms lead to
potential gains in the computational efficiency with limited data exchanges among
areas.

▼ Thanks to faster and better integrated processing units, as well as increasingly miniaturized and precise sensors, Robotics is experiencing a period of significant development.
New technology is making robots increasingly more autonomous. Data from different sensors can be fused and processed in real time by on-board processing units in order to make the robot perform either more or less complicated tasks.
Unmanned Ground Vehicles (UGV) and Unmanned Aerial Vehicles (UAV) equipped with sensors and microprocessors/microcontrollers can be remotely piloted. They can also move autonomously with the help of different navigation and localization methods.
Power electronics is contributing to a transformation in many fields such as robotics, automotive and consumer devices.
Some new applications of power electronics are discussed in the first chapter of this thesis. One of these describes how new power electronics devices allow the use of distributed instead of centralized control in industrial robotics.
Multi-sensor data fusion theory is presented in the second chapter; the Kalman Filter and Particle Filter are described.
Inertial sensors and magnetometers are introduced in the third chapter with the description of a calibration procedure for each sensor.
Two new methods of multi-sensor data fusion, based on low-cost Micro Electro-Mechanical Systems (MEMS) Inertial Sensors, to estimate joint angles of industrial manipulators are described in the fourth chapter. The results of two experimental tests are also presented to evaluate and to compare the performances of the two methods.
A method to estimate the attitude and heading of an UAV is described in the fifth chapter. In order to check the performance of the developed method, at the end of the fifth chapter, a comparison test with a high accuracy system is presented.
A localization algorithm for a wheeled UGV equipped with a GPS and an inertial platform is described in the sixth chapter. Simulation tests and experimental results are also presented at the end of the sixth chapter.

▼ Worldwide, many countries direct billions of dollars into the development of renewable energy sources; especially wind generation, in an effort to relieve global warming effects and other environmental concerns. As a result of increasing numbers of remotely-located large power offshore wind farms, the AC grid faces many technical challenges in integrating such plants; such as large submarine power transmission for extended distances, power sharing and transfer, as well as remotely located induction generation reactive power support. Offshore multi-terminal VSC based HVDC (MT VSC-HVDC) transmission systems represent a possible means of dealing with those challenges. This is due to their higher capacity, flexibility and controllability than offshore AC transmission. In addition, these offshore grids provide grid integration to remote offshore wind farms leading providing additional interconnection capacity to improve the trade of electricity between different AC grids.
This work presents a new centralized supervisory control strategy for controlling the power sharing and voltage regulation of MT VSC-HVDC integrating offshore wind farms. The main purpose of the proposed strategy is selecting the optimal parameters of the HVDC system VSCs' local controller. These optimal parameters are selected in order to achieve optimal system transient response and desired steady state operation.
In this work, an adaptive droop-based power-sharing control strategy is proposed. The primary objective is to control the sharing of the active power transmitted by a MT VSC-HVDC network among a number of onshore AC grids or offshore loads based on the desired percentage shares. The shared power is generated by remote generation plants (e.g., offshore wind farms) or is provided as surplus of AC grids. The desired percentage shares of active power are optimized by the system operator to fulfill the active power requirements of the connected grids with respect to meeting goals such as supporting energy adequacy, increasing renewable energy penetration, and minimizing losses. The control strategy is based on two hierarchal levels: voltage-droop control as the primary controller and an optimization based secondary (supervisory) controller for selecting the optimal droop reference voltages. Based on the DC voltage transient and steady state dynamics, a methodology for choosing the droop gains for droop controlled converters has been developed.
In addition, a new tuning methodology is proposed for selecting the optimum VSCs local controller gains to enhance the transient performance and the small-signal stability of the system to mitigate the change of the operating conditions, taking into consideration the overall dynamics of the MT HVDC system. The VSCs' local control loops gains are selected to maximize the system bandwidth and improve the system damping. As a part of the proposed methodology, the derivation of the aggregated linearized state-space model of a MT VSC-HVDC based offshore transmission system is provided. Based on the…

▼ Due to the dramatic hike of fossil fuel and recognition of environmental protection, the development of renewable energy and smart grid has been promoted in many countries. The Advanced Metering Infrastructure (AMI) can provide customers with the detailed information of
power consumption and electricity tariff. The time of use rate structure and more effective incentives can be revised to encourage customer for peak loading reduction to enhance
power system reliability.
This thesis has developed the smart meter to perform the monitoring and control of multiple circuits at the same time. The
power demand and energy consumption of 6 sets of 1-Ï
power circuits or 2 sets of 3-Ï
power circuits can be measured. Without requiring the installation of communication
system, all of the
power information is then transmitted back to the master station using the technology of
power line carrier. The demand control of each
power circuit can be applied to interrupt non-essential loads during the violation of contract demand. The demand response can also be executed by resetting the contract demand when the master station receives the command of demand response from the utility for the reduction of
system power demand.

▼ The transportation electrification has gained more and more attention due to its smaller carbon dioxide emission, better fuel efficiency. The recent advances in
power devices, microcontrollers, and transducers accelerate the electrification of transportation. This trend is shown in the propulsion
system in marine transport as well and the electric propulsion
system has been widely used to meet the strict environmental regulations.
However, the non-linear circuit components such as capacitor and diode in the electric propulsion
system draw non-linear current and significantly deteriorate
power quality and lead to critical problems such as reduced life span of circuit components Accordingly, a front-end is required to improve
power quality. Also, it is desired to have compact and lightweight front-end for installation flexibility and fuel efficiency improvement.
In this dissertation, several front-ends using a phase-shift transformer are reviewed and a detailed analysis is provided to help understand the harmonic cancellation principle of the existing front-end through equivalent circuit analysis, quantitative analysis, and a phasor diagram representation. Based on the analysis of the existing front-ends and shipboard
power architecture, lightweight and high-performance front-end is proposed and verified by simulation and prototype hardware.
The performance, size comparison between existing front-end and the proposed front-end is provided to show the advantage of the proposed front-end.

▼ The main objective of this research is to develop
an improved stochastic technique namely Fuzzified Particle Swarm
Optimization (FPSO) for solving various power system optimization
problems. The popularity of Particle Swarm Optimization (PSO) is
due to its significant property of dealing with the optimization
problems without any restrictions on the structure or type of the
function to be optimized and due to the ease of computation. The
various problems investigated with the proposed FPSO algorithm
include multi-constrained dynamic Economic Dispatch (ED), Emission
Constrained Economic Dispatch (ECED), Multi-Area Economic Dispatch
(MAED), Optimal Power Flow (OPF) and Security Constrained Optimal
Power Flow (SCOPF) with the incorporation of Flexible AC
Transmission System (FACTS) controllers. The purpose of Emission
Constrained Economic Dispatch (ECED) is to obtain the optimal
generation schedule by minimizing the fuel cost and emission level
simultaneously, while satisfying load demand and operational
constraints. The primary objective of Optimal Power Flow (OPF) is
to provide the electric utility with optimal set points of
operation with respect to various objectives, such as minimization
of the total generation cost, minimization of the total active
power losses and maximization of the degree of security. The
optimal solutions of multi-constrained dynamic ED, ECED, multi-area
OPF and multi-area SCOPF with multiple FACTS controller problems
obtained using Evolutionary Programming (EP), Tabu Search (TS) and
PSO based algorithms are compared with FPSO. The analysis reveals
that the FPSO algorithm has superior (faster) convergence than EP,
TS and PSO techniques for multi-constrained dynamic ED, ECED,
multi-area OPF and multi-area SCOPF with multiple FACTS controller
problems. Therefore the proposed algorithm is relatively simple,
efficient, reliable and applicable to other power engineering
optimization problems. newline

▼ This thesis proposes a new wide-area controller for enhancing the stability of power systems by damping inter-area oscillations. The obtained controller is a new nonlinear controller that accomplishes the task by using data from PMUs employed throughout the network. The controller improves the damping of inter-area oscillations by providing a supplementary control input for several controllable devices such as excitation systems of synchronous generators and Static Var Compensators. The novel nonlinear inverse filtering controller is developed and investigated in different network configurations in the thesis.

▼ Coastal zone is the region of rapid socio-economic development and the habitat of various marine lives. With the increasing complexity of land use, integrated spatial planning is important and indispensable to the development of coastal zone.
Coastal environment is a complicated
system with highly dynamic environment, coastal zone planning needs to achieve the objectives of environmental protection, economic development and ecological sustainability. To solve this planning problem, either analytic or simulation approaches have been used. However these two approaches have their own demerits in problem solving.
The purpose of this research is to develop a model combing analytic and simulation methods to solve spatial planning problem in complicated dynamic marine environment. Through combined with
Multi-Objective Programming, Fuzzy Sets Theory and
System Dynamics, a spatial planning model of dynamic
multi-objective programming approach to the coastal zone spatial planning will be constructed. It could be used in coastal zone development predicting, regional and city planning and marine policy decision making.

▼ This thesis discusses the problem of the large area consumption required to perform fast Fourier transform (FFT) operations. Fast Fourier transform architectures require a large amount of processing elements to perform its operation. The larger the required FFT size, the more processing elements needed and, therefore, a larger implementation area needed. The main sources for the area consumption are the large number of multiplications FFT computations.
In this thesis, a study has been made about most common FFT architectures like memory based FFT architectures and pipelined FFT architectures. Moreover, some studies have been made about the previously implemented FFT butterfly architectures, and some ideas about how to optimize area in the entire FFT system and inside FFT butterflies.
The objective of the thesis is to optimize the area usage inside a single FFT butterfly. Area optimization is achieved by developing a unified FFT butterfly architecture that contains multiradix FFT architectures. That concept enables the usage of fewer amount of FFT butterflies inside the system to achieve larger FFT operations. In addition, by using shift-add concept instead of multipliers, the area can be optimized significantly. Memory organization has been put into consideration when implementing the proposed FFT architectures, which implied the need of sequential version of the FFT butterflies. All these concepts were mixed together to result in a final version that is the best area-optimized in this thesis.
After implementing the various versions of FFT architectures using sharing resources, sequential processing, and shift-add concepts, their results were compared into the previously implemented traditional version. The final proposed architectures, which are sequential and multiplierless radix-2, 3, 4, 5, and multi-radix FFT architectures. From the comparison results, the proposed implementations achieved thesis objectives, resulting in about 60% of area reduction compared to the previously implemented FFT butterflies’ architectures.

▼ This dissertation expands the topics from the wide-area situational awareness application development, system architecture design, to power system disturbance analysis. All the works are grounded on the wide-area Frequency Monitoring Network (FNET). The FNET system takes GPS-synchronized wide-area measurements in a low-cost, easily deployable manner at 120V single-phase power outlet. These synchronized observations enables the monitoring of bulk power systems, and provides critical information for understanding power system disturbances and system operations.
Firstly, the work addresses the viability of angle measurement to serve different types of situational awareness applications, including the development of new angle-based event location estimation methods, the design of real-time system visualization framework using angle measurement. Secondly, a sound FNET power system event monitoring and automatic event reporting system framework is introduced, with NERC Frequency Response Initiative (FRI) tasks included to improve power system situational awareness capability. Lastly, the work covers different types of power system disturbance analysis, including the statistical analysis of frequency disturbances in NA power grid from 2008 to 2011; analysis of typical frequency response characteristics of the generation and load loss events in Europe power grid; analysis of some major disturbances in NA power grid from 2010 to 2011; and the inter-area oscillation modal analysis in the WECC system.

▼ In many cases, research on reliability analysis focuses on searching the state space of the
system for states that represent events of interest, like failure of the
system not meeting the required demand for a specific node. This raises the need for search procedures that efficiently determine states to be examined and then evaluated. Artificial Intelligence based methods have been studied for this objective either by themselves or in conjunction with widely used methods like Monte Carlo Simulation. This dissertation investigates various novel approaches for reliability evaluation of composite
power systems by combining Monte Carlo simulation (MCS) with different machine learning techniques for
Multi-Label Learning and Deep Learning topologies.
The objective in this research is reducing the computational burden to perform Monte Carlo Simulation for a given level of accuracy. As a consequence, higher accuracy can be obtained for the same level of computational effort

power systems have limited generation capacity and finite rotating inertia compared with large
power systems. Moreover, all-electric ship
power systems include large portions of nonlinear loads and dynamic loads relative to the total
power capacity, which may significantly reduce the stability margin. Pulse loads and other high-energy weapon loads in the
system draw a large amount of
power intermittently, which may cause significant frequency and voltage oscillations in the
system. Thus, an effective real-time load management technique is needed to dynamically balance the load and generation to operate the
system normally.
Multi-agent systems, inspired by biological phenomena, aim to cooperatively achieve
system objectives that are difficult to reach by a single agent or centralized controller. Since
power systems include various electrical components with different dynamical systems, conventional homogeneous
multi-agent
system cooperative controllers have difficulties solving the real-time load management problem with heterogeneous agents. In this dissertation, a novel heterogeneous
multi-agent
system cooperative control methodology is presented based on artificial potential functions and reduced-order agent models to cooperatively achieve real-time load management for all-electric ship
power systems. The technique integrates high-order
system dynamics and various kinds of operational constraints into the
multi-agent
system, which improves the accuracy of the cooperative controller. The
multi-agent
system includes a MVAC multiagent
system and a DC zone
multi-agent, which are coordinated by an AC-DC communication agent.
The developed
multi-agent
system framework and the notional all-electric ship
power system model were simulated in PSCAD software. Case studies and performance analysis of the MVAC
multi-agent
system and the DC zone
multi-agent
system were performed. The simulation results indicated that propulsion loads and pulse loads can be successfully coordinated to reduce the impact of pulse loads on the
power quality of all-electric ship
power systems. Further, the switch status or
power set-point of loads in DC zones can be optimally determined to dynamically balance the generation and load while satisfying the operational constraints of the
system and considering load priorities. The method has great potential to be extended to other isolated
power systems, such as microgrids.

▼ The
Multi-Agent-
System (MAS) technology has many desirable attributes such as autonomy, sociality, reactivity and pro-activity. It is widely accepted as the technology platform for implementing effective and efficient management and automation processes within a microgrid environment. This paper proposes an implementation of a microgrid simulation utilizing Matlab and a MAS software program. The MAS software is implemented with the aid of the Java Agent Development Framework (JADE) middleware platform. The three intelligent agents are: Controller agent, Distributed Energy Resource (DER) agent and Load agent. The Controller agent monitors network processes, performs critical control task such as network reconfiguration and it is also capable of detecting network anomaly. The DER agent stores the associated energy resources information, monitors and controls the DER
power levels. Finally, the Load agent stores information about the users and loads such as
power consumption and the priority status of the load. Both DER and Load agents are able to interact and respond to Controller agent’s command for connecting / disconnecting from the
power network. This simulation will demonstrate the benefits of employing a standard MAS environment that could serve as a platform for studying real-time microgrid’s communication, monitor and control technologies.

▼ This dissertation presents a new modeling and analysis frameworks, and novel control architectures for wide-
area power oscillation damping using wind farms in a Networked Controlled future smart grid.
First, a unified modeling framework for Networked Controlled
Power System (NCPS) with wind farms is presented, which is suitable for dynamic simulation during planning studies. A modified dynamic model of Doubly-Fed Induction Generator (DFIG) is proposed to represent the wind farms. The framework also considers a detailed characterization of the communication process with packet loss probability represented by the Gilbert-Elliott model. A modeling adequacy study of the NCPS with different degree of details in the DFIG model and the data packet dropout model is considered for analyzing the performance of wide-
area
power oscillation damping control. It is shown that such packet drop deteriorates the damping controller performance.
To solve this problem, an Observer-driven Reduced Copy (ORC) approach is proposed that uses the knowledge of the nominal
system dynamics represented by a reduced-order linear model called ‘reduced copy’ during data dropouts. When a data sample is available, the states of the reduced copy are reset to the newly obtained values. Moreover, two performance measures of the ORC approach are derived. The first performance measure is based upon a bound on the norm of the difference between the
power system states in presence of the data dropout and that under ideal communication within an inter-sample interval. This bound is an explicit measure of the performance of ORC impacted by the data dropout. The second measure is based on a bound on the inter-sample error norm between
power system states and ‘reduced copy’ states. This measure reveals the impact of the cyber layer, the physical layer, and the interaction between these layers.
Next, a novel
multi-input
multi-output (MIMO)-ORC architecture is proposed in which each of the multiple actuators uses a MIMO ‘reduced copy.’ The concepts of cyber-physical ‘self-coupling’ and ‘cross-coupling’ are introduced in the context of MIMO- and SISO-ORC architectures. Then, a framework for stability analysis of the MIMO-ORC architecture is also presented.
The MIMO-ORC architecture needs a reduced-order MIMO linear model of the
power grid, which includes DFIG-based wind farms. The difficulty in reducing such models using gramian-based and modal truncation approaches is demonstrated next. To solve this, a relatively new Interpolatory approach of Iterative Rational
Krylov Algorithm (IRKA) is presented that shows promising results. Moreover, a Heuristic-based IRKA (H-IRKA) is proposed to improve the accuracy of model order reduction of such models with explicit preservation of the ‘critical modes’ of the
system. Finally, after deriving a stable reduced-order MIMO model of the grid with wind farms, which explicitly preserves the critical modes of interest, its effectiveness is tested on the MIMO-ORC architecture.

▼ Due to the increasingly complex behavior exhibited by large-scale power systems with more uncertain renewables introduced to the grid, wide-area measurement system (WAMS) has been utilized to complement the traditional supervisory control and data acquisition (SCADA) system to improve operators’ situational awareness. By providing wide-area GPS-time-synchronized measurements of grid status at high time-resolution, it is able to reveal power system dynamics which cannot be captured before and has become an essential tool to deal with current and future power grid challenges. According to the time requirements of different power system applications, the applications can be roughly divided into online applications (e.g., data visualization, fast disturbance and oscillation detection, and system response prediction and reduction) and offline applications (e.g., measurement-driven dynamic modeling and validation, post-event analysis, and statistical analysis of historical data).
In this dissertation, various wide-area measurement-based applications are presented. Firstly a pioneering WAMS deployed at the distribution level, the frequency monitoring network (FNET/GridEye) is introduced. For conventional large-scale power grid dynamic simulation, two major challenges are 1) accuracy of detailed dynamic models, and 2) computation burden for online dynamic assessment. To overcome the restrictions of the traditional approach, a measurement-based system response prediction tool using a Multivariate AutoRegressive (MAR) model is developed. It is followed by a measurement-based power system dynamic reduction tool using an autoregressive model vi to represent the external system. In addition, phasor measurement unit (PMU) data are employed to perform the generator dynamic model validation study. It utilizes both simulation data and measurement data to explore the potentials and limitations of the proposed approach. As an innovative application of using wide-area power system measurement, digital recordings could be authenticated by comparing the extracted frequency and phase angle from recordings with power system measurement database. It includes four research studies, i.e., oscillator error removal, ENF phenomenology, tampering detection, and frequency localization. Finally, several preliminary data analytics studies including inertia estimation and analysis, fault-induced delayed voltage recovery (FIDVR) detection, and statistical analysis of oscillation database, are presented.

▼ This dissertation presents wide-area measurement-driven approaches for power system modeling and analytics. Accurate power system dynamic models are the very basis of power system analysis, control, and operation. Meanwhile, phasor measurement data provide first-hand knowledge of power system dynamic behaviors. The idea of building out innovative applications with synchrophasor data is promising.
Taking advantage of the real-time wide-area measurements, one of phasor measurements’ novel applications is to develop a synchrophasor-based auto-regressive with exogenous inputs (ARX) model that can be updated online to estimate or predict system dynamic responses.
Furthermore, since auto-regressive models are in a big family, the ARX model can be modified as other models for various purposes. A multi-input multi-output (MIMO) auto-regressive moving average with exogenous inputs (ARMAX) model is introduced to identify a low-order transfer function model of power systems for adaptive and coordinated damping control. With the increasing availability of wide-area measurements and the rapid development of system identification techniques, it is possible to identify an online measurement-based transfer function model that can be used to tune the oscillation damping controller. A demonstration on hardware testbed may illustrate the effectiveness of the proposed adaptive and coordinated damping controller.
In fact, measurement-driven approaches for power system modeling and analytics are also attractive to the power industry since a huge number of monitoring devices are deployed in substations and power plants. However, most current systems for collecting and monitoring data are isolated, thereby obstructing the integration of the various data into a holistic model. To improve the capability of utilizing big data and leverage wide-area measurement-driven approaches in the power industry, this dissertation also describes a comprehensive solution through building out an enterprise-level data platform based on the PI system to support data-driven applications and analytics. One of the applications is to identify transmission-line parameters using PMU data. The identification can obtain more accurate parameters than the current parameters in PSS®E and EMS after verifying the calculation results in EMS state estimation. In addition, based on temperature information from online asset monitoring, the impact of temperature change can be observed by the variance of transmission-line resistance.

Power System Dynamics Enhancement Through Phase Unbalanced and Adaptive Control Schemes in Series FACTS devices.

▼ This thesis presents novel series compensation schemes and adaptive control techniques to enhance
power system dynamics through damping Subsynchronous Resonance (SSR) and low-frequency
power oscillations: local and inter-
area oscillations. Series capacitive compensation of transmission lines is used to improve
power transfer capability of the transmission line and is economical compared to the addition of new lines. However, one of the impeding factors for the increased utilization of series capacitive compensation is the potential risk of SSR, where electrical energy is exchanged with turbine-generator shaft systems in a growing manner which can result in shaft damage. Furthermore, the fixed capacitor does not provide controllable reactance and does not aid in the low-frequency oscillations damping.
The Flexible AC Transmission
System (FACTS) controllers have the flexibility of controlling both real and reactive
power which could provide an excellent capability for improving
power system dynamics. Several studies have investigated the potential of using this capability in mitigating the low-frequency (electromechanical) as well as the subsynchronous resonance (SSR) oscillations. However, the practical implementations of FACTS devices are very limited due to their high cost.
To address this issue, this thesis proposes a new series capacitive compensation concept capable of enhancing
power system dynamics. The idea behind the concept is a series capacitive compensation which provides balanced compensation at the
power frequency while it provides phase unbalance at other frequencies of oscillations. The compensation scheme is a combination of a single-phase Thyristor Controlled Series Capacitor (TCSC) or Static Synchronous Series Compensator (SSSC) and a fixed series capacitors in series in one phase of the compensated transmission line and fixed capacitors on the other two phases. The proposed scheme is economical compared to a full three-phase FACTS counterpart and improves reliability of the device by reducing number of switching components.
The phase unbalance during transients reduces the coupling strength between the mechanical and the electrical
system at asynchronous oscillations, thus suppressing the build-up of torsional stresses on the generator shaft systems. The SSR oscillations damping capability of the schemes is validated through detailed time-domain electromagnetic transient simulation studies on the IEEE first and second benchmark models. Furthermore, as the proposed schemes provide controllable reactance through TCSC or SSSC, the supplementary controllers can be implemented to damp low-frequency
power oscillations as well. The low-frequency damping capability of the schemes is validated through detail time-domain electromagnetic transient simulation studies on two machines systems connected to a very large
system and a three-
area, six-machine
power system. The simulation studies are carried out using commercially available electromagnetic transient simulation tools (EMTP-RV and PSCAD/EMTDC).

▼ The main purpose of this thesis was to develop a printed circuit board for Autoliv Electronics AB. This circuit board should be placed in their test equipment to support some of their camera vision systems used in cars. The main task was to combine the existing hardware into one module. To be able to achieve this, the most important factors in designing a printed circuit board was considered. A satisfying power distribution network is the most crucial one. This was accomplished by using decoupling capacitors to achieve low enough impedance for all circuits. Calculations and simulations were executed for all integrated circuits to find the correct size and numbers of capacitors. The impedance of the circuit board was tested with a network analyzer to confirm that the impedance were low enough, which was the case. System functionality was never tested completely, due to delivery problems with some external equipment.

stringenti posti dagli enti regolatori nazionali sulla riduzione della durata e della frequenza delle interruzioni (già con la Delibera 333/072 dell Autorità per l Energia Elettrica ed il Gas -AEEG- in Italia), accanto alla spinta verso l implementazione di nuovi scenari complessi di gestione delle reti, pongono fortemente la necessità che la ricerca si orienti verso l estensione delle metodologie tradizionali di calcolo analitico dell affidabilità ai nuovi paradigmi della distribuzione con l affinamento di nuovi e idonei strumenti di analisi.
Il secondo filone, attinente piuttosto al perseguimento di obiettivi di efficienza e limitazione delle emissioni inquinanti è relativo all esercizio di microreti, in linea con le politiche internazionali di gestione dei sistemi elettrici. Ci si è occupati dell ottimizzazione del dispacciamento delle risorse di produzione
ed accumulo presenti in una microrete. La procedura di ottimizzazione si basa
sull utilizzo del SALHE-EA (acronimo di Self-Adaptive Low-High Evaluation
Evolutionary Algorithm). In particolare, l obiettivo è quello di individuare i set-point ottimali dei generatori programmabili e dei sistemi di accumulo al fine di minimizzare i costi di funzionamento e manutenzione dei generatori stessi, riducendo al contempo le emissioni inquinanti da questi prodotte ed assumendo che tutta la potenza disponibile dalle fonti di energia rinnovabile fosse iniettata nella Microrete o accumulata per essere in seguito fornita secondo un apposita strategia di gestione delle unità di accumulo.
