▼ Power systems within smart grid architectures are generally large scale and have a tendency to exhibit multiple time-scales when modeled in their entirety due to the presence of physical components of different nature and parasitic parameters associated with them. Research in current literature primarily focuses on studying power system architectures based on a two time-scale decomposition. In this dissertation, we use singular perturbation theory to investigate time-scale decomposition and related anomalies and propose new control methods by considering the presence of multiple time-scales. We start with an open-loop study of a simplified model of an islanded microgrid in singularly perturbed form with highly oscillatory and highly damped modes. Simulation results and analytical analysis conclude that the model does not contain any slow time-scales even though the eigenvalue distribution of the model tells otherwise. While the singular perturbation parameter is very small, the classical two time-scale decomposition in this case is not effective. On the other hand, the modes corresponding to the fastest time-scales provide a very accurate approximation of the original model. The results obtained via singular perturbation methods are also corroborated by using the balancing realization technique. Namely, only the states corresponding to the fastest modes are dominant. Motivated by the structure of the state-space input matrix of the previous problem, we consider a new class of singularly perturbed systems where individual inputs control slow and fast modes independently. We study the linear quadratic regulator optimal control problem for three cases that are common in real physical systems, namely when the inputs are completely decoupled or independent, when weak coupling is present between the inputs, and when the fast subsystem is weakly controlled. We obtain the zero-order approximation solution of the continuous algebraic Riccati equations for each case in terms of simplified sub-problems which avoid possible ill-conditioning. As a follow-up, parallel recursive algorithms based on fixed-point methods are proposed to improve the error of the approximations leading to the accurate solution of Riccati equations and the cost functional in a few iterations of the algorithm. These results are further extended to the stochastic case. The linear-quadratic Gaussian control problem is investigated and its solution is also obtained very accurately in an iterative fashion. Lastly, implicit singularly perturbed systems with multiple time-scales are considered. The Schur decomposition is utilized to transform the control matrix into an upper quasi-triangular form where the time-scales are explicitly ordered and a singularly perturbed model is obtained after perturbation parameters are evaluated and extracted. The standard multi-time-scale system is then decoupled into individual time-scales by sequentially applying an invariant transformation. Multi-time-scale control of the Schur-decomposed system is then considered.… Advisors/Committee Members: Gajic, Zoran (chair), Godrich, Hana (internal member), Pompili, Dario (internal member), Yi, Jingang (internal member), Zhong, Ningfan (outside member).

▼ This thesis investigates the impact that home charging of a large private fleet of electric vehicles would have on the power system. A large multi-regional travel survey dataset is used to model vehicle use and charging spatially heterogeneously, and a selection of representative network models are used to assess the impact of charging on system operation. A stochastic data-driven model is proposed to model uncontrolled charging of vehicles, and convex optimisation is used to calculate the optimal smart charging strategy. The power system is commonly broken down into the generation, transmission, and distribution systems. The operation of each of these systems will be impacted by the addition of EV charging to residential networks. A variety of objectives have been proposed for smart charging, each of which would protect the system in a different way. Existing research tends to focus on a single part of the system, and considers only the smart charging objective that most benefits that part of the system. Here, the three systems are modelled simultaneously, and a large range of smart charging objectives are investigated. The value of explicit loss minimising smart charging is quantified, compared to a simpler and more standard load flattening algorithm. These results are used to propose a novel optimisation formulation which reduces losses without requiring extensive network information. The value of bi-directional smart charging is also quantified compared to uni-directional smart charging, in order to investigate the viability of residential vehicle-to-grid. It is demonstrated that it is not possible to optimise the transmission level and distribution level systems simultaneously, and the penalty of only optimising for one is quantified. A method for finding a compromising solution between both system levels is proposed, which exploits the sections of the distribution where components are over-specified. Two specific case studies are investigated. The majority of the analysis in the thesis is based on the GB power system, however the Texas system is also presented as a comparative case study.

▼ Smart meter implementations are still in their infancy in many African countries. This is evident by the lack of research on the subject in the African context. Most of the research studies are either Eurocentric or US-centric. Although these studies are important and informative, they might not address the African challenges in context. Hence, South Africa was chosen as the testbed for an investigation that addresses the apparent knowledge gap. This study set out to formulate a framework for planning considerations in the implementation of smart meter technology within South Africa. Through extensive literature review and analysis, the technology acceptance model (TAM) was chosen as a foundational framework for this study. Although TAM is widely used for researching technology acceptance and use, its applicability was found to be inadequate in explaining customer centric factors in smart metering. Therefore, it was supplemented with factors from the theory of reasoned action (TRA), the theory of planned behavior (TPB), privacy calculus theory (PCT), as well as the unified theory of acceptance and use of technology (UTAUT). A total of 11 consumer-centric factors were identified, and these were statistically analysed using the structural equation modelling technique (SEM). Ten (10) consumer-centric factors was found to be significant. These were attitude, perceived value, monetary cost, privacy risk, perceived ease of use, perceived usefulness, facilitating conditions, social norms, trust in technology and behavioral intention. Hypothesis testing confirmed that, not one acceptance model could adequately be used to identify and explain the consumer-centric factors that can be incorporated for planning considerations for smart meter implementation in South Africa. It was further observed that the consumer-centric factors such as environmental issues, security, reliability and health issues that were important in developed countries were not deemed so in South Africa. From a methodological perspective, the study attests to contextual localised application as opposed to universal meaning and measurement invariance when incorporating planning consideration for smart meter implementation in South Africa as compared to European countries and the United States of America. Finally, the findings hold some practical implications, as they showed the practical utility of the model in predicting the consumer-centric factors that can be incorporated for planning considerations. In support, the Business Model Canvas (BMC) was found to be a useful tool in deriving and reporting on the formulation of planning consideration guidelines. Using the BMC, five planning consideration guidelines were derived: customer segmentation, partnerships, benefits communication, value identification and customer attitude. These planning considerations will allow smart meter providers to identify their customers, partners and value propositions they might need to offer consumers to facilitate a higher smart meter acceptance and use. The proposed planning…

▼ We propose learning and optimization algorithms for the next generation power systems. First, we design distributed algorithms to schedule the charging of electric vehicles. By implementing the algorithms, we obtain a favorable total load profile, while accounting for the capacity constraints induced by the power grid distribution lines and other components such as transformers. We further propose a novel algorithm for distributed charging control of electric vehicles using online learning. Many of the existing distributed charging control algorithms in the literature implicitly assume fast two-way communication between a distribution company and electric vehicle customers. This assumption may be impractical at present. Our algorithm does not impose such an assumption. The proposed algorithm requires one-way communication, which is implemented through the distribution company publishing the pricing profiles of the previous days. Second, we propose a distributed algorithm for online energy management in networked microgrids with a high penetration of distributed energy resources. In general, the state-of-the-art forecasting for distributed energy resources such as solar is not sufficiently accurate, which results in inaccurate energy scheduling. To address the high uncertainty issues, we propose an online energy management algorithm and use the historical data about the power generation from the distributed energy resources to proceed. The proposed energy management algorithm does not require the online algorithm to be fully executed, which further reduces the burden on the wireless communication spectrum usage. In the last part of this dissertation, we study the alternating current optimal power flow problem in the smart grids. In the alternating-current model, optimal power flow becomes a notoriously difficult non-convex non-linear optimization problem. We introduce two novel methods for solving the semidefinite programming relaxations of the alternating current optimal power flow problem in the literature. First, we present a method to include the block constraints from a higher-order semidefinite programming relaxation one-by-one, as required, to converge to the objective function value of the higher-order relaxation. Second, we present a method for solving the resulting semidefinite programming relaxations based on the block-coordinate descent method for the associated augmented Lagrangian.

▼ The growing concerns with global warming prompted many governments to mandate increased proportion of electricity generation from renewable sources. This, together with the desire to have more efficient and secure power generation and distribution, has driven research in the next-generation power grid, namely, the smart grid. Phasor measurement units (PMU) are measuring devices that offer accurate and time-synchronized phasor data to the control center. They can significantly improve the performances of power system monitoring and control and, therefore, are considered the fundamental components in the smart grid. However, since they are expensive devices and generate excessive amount of data traffic, two major questions have to be properly addressed before they can be fully utilized: How do we install PMUs in an economical manner to achieve full system observability? And how do we build up the communication system that can support this number of PMUs in the system? In this dissertation, we first propose a three-entity smart grid communication framework that focuses on the communication systems enabling smart grid. This communication framework lays the foundation for the rest of the thesis. We start by solving the PMU placement in very large power systems using a meta-heuristic algorithm called simplified chemical reaction optimization (SCRO). After that, we propose the optimal multistage PMU placement (OMPP) problem to address the economic issues brought about by massive scale PMU installations and solve it using SCRO. Then we investigate techniques to alleviate the short-term data communication burdens by optimally installing phasor data compression units (PDCU) to reduce overall system bandwidth requirements. We make this optimal PDCU installation (OPI) problem readily solvable by commercial software by formulating it under the integer linear programming (ILP) framework. Last but not least, we formulate the optimal PMU-communication link placement (OPLP) problem that gives an answer to the question: if one wants to build aWAMS for smart grid, what is the most economic way to do so considering both the costs of PMU placement and the installation costs of a communication network that supports these PMUs? The OPLP problem is formulated under the integer quadratic programming (IQP) framework.

▼ With the raising standard of safe and reliable operation of power system and integrating more fluctuating renewables, operational flexibility and resilience become challenges for power system operation. At the same time, the structures of power grids have greatly changed. Unidirectional and coal-fired generators dominated power grids are gradually replaced by the bidirectional power grids with renewables, distributed generators, controllable loads, and energy storage with more powerful communication abilities. In this thesis, the research is focused on enhancing the operational flexibility and resilience for power grids. These targets are achieved by facilitating the energy balancing with innovative control strategies and devices. In particular, energy storage and electric springs (ES) as the new smart load technology are used. The main studies are as follows. For bulk power grids, the power ramps generated during the switching of operating modes for pumped storage units are proposed to improve operational flexibility by facilitating frequency regulation under the event of net load ramping up and down. For microgrids, battery energy storage system (BESS) is proposed to enhance the resilience of an islanded microgrid, which contains conventional generators with limited ramping ability and fluctuating renewables, by facilitating regulating frequency and voltage. A dynamic model is proposed to evaluate the SOC of BESS accurately, that is essential for regulating frequency with the BESS of small energy capacity. ESs are also proposed to improve the operational flexibility and resilience for islanded microgrids in this thesis. By installing ESs, the non-critical loads (NCLs) can be treated as a controllable operating resource to enhance the operational flexibility and resilience for islanded microgrids with limited operating resources. The feasible operating region of ES is obtained in closed form by deriving the physical model of an individual ES. By associating the physical models of individual ES with AC power flows, the control ability of an ES can be well addressed in this thesis while considering the interactions with other devices in a power grid. In order to adequately address the dynamic process and constraints of different physical system and devices, model predictive control (MPC) method is applied for the proposed control strategies of pumped storage unit, BESS and ES. A graphics processing unit (GPU) based computing platform is proposed to solve the optimal switching time for a pumped storage unit within seconds. The orders of computational complexity with the size of AGC system and the length of control horizons can be reduced by the parallel computing based structure on the GPU platform. The pumped storage units, ESs, and BESSs can effectively contribute on enhancing the operational flexibility and resilience of future power grids with these methods and technologies. Based on the above works in this thesis, new technologies, devices, and strategies are proposed to overcome the major challenges,…

▼ Modern power systems worldwide are faced up with a series of challenges transforming towards a more intelligent and resilient electricity network commonly known as smart grid. Myriads of techniques and measures have been introduced to the existing grid ranging from generation side to end-user side. Our work focuses on two aspects of smart grid namely photovoltaic (PV) energy and smart meter. Due to the increasing demand for sustainable resources, PV energy has been widely adopted in various landscapes. Partial shading can drastically alter the output power-voltage characteristics of PV systems, resulting in a modified profile with both global and local optimal power points. Many studies of global maximum power point tracking (GMPPT) are conventionally based on one or several fixed (steady-state) shading conditions. In reality, partial shading is changing dynamically and so is the location of the GMPP. In this thesis, we present a simple and yet effective method for modeling dynamic partial shading of PV systems. The shaded areas on the PV arrays can change shape and position with time. This dynamic partial shading modeling approach enables the dynamics of GMPPT controllers to be evaluated. The dynamics of this modeling method has been successfully confirmed in Matlab simulation and experimentally verified with a sliding-mode controller and a proportional-integral controller. The proposal can be used as a design tool for GMPPT controller as well as an educational tool to illustrate the dynamic changes of the output power-voltage profiles. Smart meter is increasingly important in providing essential communication between utilities and consumers. However, traditional smart meter requires professional installation which significantly encumbers the replacement process. In this thesis, we describe a non-intrusive power measurements method that is suitable for a new type of low-cost and easy-to-install smart meters in (i) measuring current and power from parallel electric cables based on non-contact magnetic flux and (ii) differentiating the power consumption of each phase. By placing non-contact magnetic flux sensors close to the parallel electric cables that carry electric currents, standard techniques obtain the current information in the cables by measuring the magnetic flux values and use cancellation algorithms to reduce the mutual coupling effects among the magnetic fields generated by these cables. Based on the use of the mains voltage of the electronic control as a reference, a new and simple method for accurately differentiating the phase currents and power in the cables and estimate the power delivered through these cables is proposed. The proposed method has been verified with practical measurements with good accuracy.

Thesis Ph. D. Michigan State University. Electrical Engineering 2014.

Optimization and control is a core part of Energy Management System (EMS), which receives the data from supervisory control and data acquisition (SCADA) system, analyzes the data centrally and provides decision actions to the system operators. Unlike conventional power system, smart grid and microgrid are more complex, dynamic and flexible, which requires a high level of computational intelligence, speed and flexibility. This dissertation presents a linearized model to analyze the optimization problem of smart grid, which can provide speed advantage as well as enough accuracy. In the meantime, a distributed multi-agent based control system is proposed in this dissertation for a flexible control of microgrids.With the development of smart grid, power electronic control devices, such as Flexible AC Transmission Systems (FACTS), are introduced into power system. They can help system operators adjust real and reactive power flows, provide voltage support or regulate voltage. The way to determine the optimal size and location to install FACTS devices is a nonlinear optimization problem. Various nonlinear techniques have been proposed and developed to solve this optimization model, such as descent methods, Newton's methods, gradient projection methods, interior methods and so on. These nonlinear methods, to some extent, can provide accurate optimal solutions; however, they are usually computationally expensive when dealing with large power systems with tens of thousands of buses. And this computational speed sometimes cannot satisfy system operators' requirements. Therefore, many industrial applications have utilized a DC optimal power flow model which assumes a flat voltage magnitude over the system. This model can achieve the results very fast, but it sacrifices accuracy and reactive power information. To reach a better trade-off between accuracy and speed, in the first half of this dissertation, it proposed a linearized power flow model for studying benefit of FACTS devices. This linear model can achieve better accuracy than DC power flow model and maintain reactive power information while the computational speed is not sacrificed.In the meantime, the increasing penetration of renewable energy and its potential accommodation paradigm, microgrids, restrict traditional central control structure in terms of cost, flexibility and reliability. Distributed control is able to address these challenges in three aspects: more economic efficiency by utilizing low-cost devices; more flexibility in terms of time-varying and adaptive configurations or functions; and more robustness by continuing working in the presence of single-point failure. For the power balance control, this dissertation first proposed a distributed multi-agent system without considering network losses and voltage regulation. In this proposed system, the information flows in parallel and results are obtained in a non-iterative way; therefore, this method achieves superior performance in…

▼ This thesis presents various advanced control strategies in smart microgrid applications. In recent years, due to the rapid depletion of fossil fuels, increasing demand of electricity, and more strict compulsory government policies on reduction of greenhouse gas emissions, renewable energy technologies are attracting more and more attentions and various types of distributed generation (DG) sources, such as wind turbine generators and solar photovoltaic (PV) panels, are being connected to low-voltage distribution networks. Because of the intermittent nature of the renewable energy sources, it would be a good idea to connect these DG units together with energy storage units and loads to form a local micro power system, known as microgrid. This PhD thesis project aims to develop new and competitive control methods for microgrid applications. Based on a review of the state of the art of the wind power techniques, a new predictive direct control strategy of doubly fed induction generator is proposed. This method can achieve fast and smooth grid synchronization, and after grid connection, the active and reactive power can be regulated flexibly, which enables the wind power systems contributing to the grid voltage support and power quality improvement. The proposed strategy is simple and reliable, and presents excellent steady-state and dynamic performance. A new control approach using the model predictive scheme is developed for a PV system in microgrid applications. In the islanded operation, the inverter output voltage is controlled stably for the local loads. A simple synchronization scheme is introduced to achieve seamless transfer, and after being connected to the utility grid, the PV system can inject both active and reactive power into the grid flexibly within its capacity. As the capacity of DGs getting larger, the power conversion efficiency becomes more important. In order to reduce the switching loss, a multi-objective model-predictive control strategy is proposed for the control of high power converters. By revising the cost function properly, the switching frequency can be reduced considerably without deteriorating the system performance. The control strategy is simplified using a graphical algorithm to reduce the computational burden, which is very useful in practical digital implementation where high sampling frequency is required. The proposed method is very flexible and can be employed in both AC/DC and DC/AC energy conversions in microgrids. For a microgrid consisting of several DG units, various system level control methods are studied. A novel flux droop control approach is developed for parallel-connected DGs by drooping the inverter flux instead of drooping the inverter output voltage. The proposed method can achieve autonomous active and reactive power sharing with much lower frequency deviation and better transient performance than the conventional voltage droop method. Besides, it includes a direct flux control (DFC) algorithm, which avoids the use of proportional-integral (PI) controllers and…

▼ Electricity service providers (ESP) worldwide have increased their interest in the use of electrical distribution, transmission, generation, storage, and responsive load resources as integrated systems. Referred to commonly as "smart grid," their interest is driven by widespread goals to improve the operations, management and control of large-scale power systems. In this thesis I provide research into a novel agent-based simulation (ABS) approach for exploring smart grid system (SGS) dispatch, schedule forecasting and resource coordination. I model an electrical grid and its assets as an adaptive ABS, assigning an agent construct to every SGS resource including demand response, energy storage, and distributed generation assets. Importantly, real time is represented as an environment variable within the simulation, such that each resource is characterized temporally by multiple agents that reside in different times. The simulation contains at least as many agents per resource as there are time intervals being investigated. These agents may communicate with each other during the simulation, but only agents assigned to represent the same unique resource may exchange information between time periods. Thus, confined within each time interval, each resource agent may also interact with other resource agents. As with any agent-based model, the agents may also interact with the environment, in this case, containing forecasted environment, load and price information specific to each time interval. The resulting model is a time-independent global approach capable of: (1) capturing time-variant local grid conditions and distribution grid load balancing constraints; (2) capturing time-variant resource availability and price constraints, and finally, (3) simulating efficient unit-commitment real-time dispatches and schedule forecasts considering time-variant forecasted transactive market prices. This thesis details the need for such a system, discusses the form of the ABS, and analyzes the predictive behavior of the model through a critical lens by applying the resulting proof-of-concept simulation to a set of comprehensive validation scenarios. The resulting analysis demonstrates ABS as an effective tool for real-time dispatch and SGS schedule forecasting as applied to research, short-term economic operations planning and transactive systems alike. The model is shown to converge on economic opportunities regardless of the price or load-forecast shape and to correctly perform least-cost dispatch and schedule forecasting functionality.

▼ A stable and reliable electrical power supply system is an inevitable pre-requisite for the technological and economic growth of any nation. Due to this, utilities must strive and ensure that the customer’s reliability requirements are met and that the regulators requirements are satisfied at the lowest possible cost. It is known fact around the world that 90% of the customer service interruptions are caused due to failure in distribution system. Therefore, it is worth considering reliability assessments as it provides an opportunity to incorporate the cost or losses incurred by the utilities customer as a result of power failure. This must be considered in the planning and operating practices. The system modelling and simulation study is carried out on one of the district’s distribution system which consists of 132 kV, 66 kV and 22 kV network in Aliwal North Sector ECOU. The reliability assessment is done on the 22, 66 and 132 kV system to assess the performance of the present system and also predictive reliability analysis for the future system considering load growth and system expansion. The alternative which gives low SAIDI, SAIFI and minimum breakeven costs is being assessed and considered. The reliability of 132 kV system could be further improved by constructing a new 132 kV line from a different source of supply and connecting with line coming from another district (reserve) at reasonable break even cost. The decision base could be further improved by having Aliwal North Sector context interruption cost. However, the historical data which may be used in Aliwal North Sector to acquire interruption costs from the customers are being proposed. The focus should be on improving the power quality on constrained networks first, then the reliability. Therefore for the Aliwal North power system network it is imperative that Eskom invest on the reliability of this network. This dissertation also analysed load reflected economic benefit versus performance expectations that should be optimized through achieving a balance between network performance (SAIDI) improvement, and total life cycle cost (to Eskom as well as the economy). Reliability analysis conducted in this dissertation used Aliwal North power system network as a case study; the results proved that the system is vulnerable to faults, planned and unplanned outages. Reliability evaluation studies were conducted on the system using DigSilent software in conjunction with FME. These two models gave accurate results with acceptable variance in most indices except for the ENS where the variance was quite significant. It can be concluded that DigSilent results are the most accurate results in all three reliability evaluation scenarios for the Aliwal North Power System, best interpretation being that of DigSilent.

▼ Nowadays renewable energy sources (RES) are growing at a rapid pace, particularly the wind energy. The high amount of wind power penetration into the power grids poses a major challenge to Transmission System Operators (TSO) in terms of the operational management, as wind power is highly uncertain. The highly uncertain nature of the wind power leads to the scenarios where the power flow exceeds the grid limits leading to the capacity problem of the grid. There are multiple solutions to prevent this grid capacity problem. The first solution is the physical extension of the grid, but this requires considerable capital investments. Moreover, the frequency of the worst-case scenarios (maximum generation coinciding with minimum load) is very low and grid expansion is a much slower process, so this solution is not optimal. The second solution is to store the excessive power using batteries. The batteries cannot store power efficiently because of the storage losses and they also degrade with time. The initial setup of the batteries and their replacement (in the case of degradation) would require considerable capital investments. The third solution is reserve regulation of the generation units to deal with the uncertainty of wind power. The final solutions is to curtail excessive wind power in the grid. The last two solutions are feasible from an economic point of view when compared to the initial two solutions. However, both these approaches are expensive. But, an optimal combination of these approaches might result in an enhanced solution in terms of total energy procurement costs (a cheaper solution). The objective of this thesis is to formulate a chance-constrained multivariate stochastic optimization problem which would perform the stochastic unit commitment and simultaneously would create an optimal combination of wind power curtailment and reserve scheduling to reduce the overall costs of the system. As an initial step, the combination of the reserves and wind power curtailment (the convex combination approach) was modeled using the convex combination approach. The optimization problem corresponding to the convex combination model was formulated to find an optimal combination of reserve dispatch and wind power curtailment. Later on, the combination of reserve scheduling and the wind power curtailment was modeled using the mixed logic dynamical systems framework (MLD approach). The optimization problem corresponding to the MLD approach was formulated to find an optimal combination of reserve dispatch and wind power curtailment. A randomization technique was used to generate various scenarios of the uncertain wind power. Based on a prior violation level of the grid limits, we perform scenario-based stochastic optimization to obtain an optimal combination of reserve scheduling and wind power curtailment in both the approaches for each scenario to lower the overall costs of the system. The theoretical developments proposed were evaluated on an IEEE-30 bus network.

▼ Electricity access is seen as an economic growth enabler and a commodity to improve people's welfare. Hence, electrification is one of the aspects highly regarded by governments worldwide. In Africa, electricity access is still a challenge, this is well illustrated by the low electrification rate of 41%, which is more significant in sub-Saharan region with an electrification rate of 35%. In this part of the continent, on one hand, the reliability of the power supply in electrified areas is still an issue and on the other hand, in areas far from the grid, there are less perspective for grid extension if considered the financial situation and top down model of grid extension used by the utilities. This leads to the extensive use of diesel generators in urban and rural areas. The traditional top down model for grid extension requires huge capitals that are mainly provided by the utility. The return on investment on extended grid determines the approval for extension or not. It is difficult for remote rural areas with no major economic activities like mining to cross the threshold of return on investment acceptable by the utility. Hence new approaches are sought to increase the electrification rate in Africa while maintaining the cost as minimum as possible. Bottom up grid extension using swarm electrification and off-grid solutions such as microgrids are gaining interest of researchers as alternative to the traditional method. It is in this line that this thesis entitled "Intermediate Low Voltage Direct Current (ILVDC) interconnection systems for sparse electrified areas" is looking into combining both approaches by building up a network from the bottom considering the locally available off-grid solutions such as nanogrid diesel generators for microgrids formation. "Olympic rings" microgrids approach is used to extend the electrified areas and anticipate an eventual interconnection with the grid. For this end, nanogrid and microgrid networks are developed, designed and tested. Bi-directional Nanogrid converter are designed with modularized topology to allow easy and economic repair as only affected module should be replaced if needed. Proposed bidirectional converters for nanogrid, microgrid and minigrid are modelled and simulated in PSIM environment. Simulation results show that the design criteria set are met by the converters. Control strategies for power exchange within nanogrids and microgrids, as well as the overall control are proposed. Communication based control strategy algorithms for nanogrids and microgrids are developed. Power line communication (PLC) technique is adopted as a communication system while a DC opto-capacitive coupler for PLC communication system is developed to enhance the safety of the equipment and users. Interconnection of microgrids through ILVDC network is performed with respect to IEC60038 and IEEE 1547. Load flow analysis using DigSilent PowerFactory is performed on individual and interconnected microgrids, with contingency scenario in the latter case.

▼ The steadily increasing need for electrical power, rising costs of energy, market forces and industry deregulation, an aging infrastructure, tight constraints on new long distance transmission lines, global environmental concerns, and a public demand for greater electrical reliability and security are overwhelming our existing power system. One technology that offers solutions to many of these challenges and addresses smart grid objectives directly is: microgrids. A microgrid is a small (typically several MW or less in scale) power system incorporating distributed generators, load centers, potentially storage, and the ability to operate with or apart from the larger utility grid. Properly managed, assets connected within a microgrid can provide value to the utility power network, improve energy delivery to local customers, and facilitate a more stable electrical infrastructure, benefitting environmental emissions, energy utilization, and operational cost. While microgrids can achieve significant improvements for customers and utilities alike, microgrid research is in its infancy and, to date, a comprehensive means of managing microgrid operations has not been realized. In this work, two primary efforts are undertaken. First, given the lack of a comprehensive software test bed for microgrids, a simulation environment capable of incorporating microgrid operational concepts, electrical modeling, asset dynamics, and control conditions is developed. Second, using the simulation environment, an enhanced decentralized multi-agent power management and control system is designed and evaluated for the purpose of supervising multiobjective microgrid operations under normal and emergency conditions. Results presented demonstrate effective multi-agent methods that yield improved microgrid performance, as well as facilitate coordinated system decision-making without reliance on a centralized controller. These advancements represent innovation towards the autonomous operation of microgrids, as well as provide important insight into new tradeoff considerations associated with multi-objective design for power management. Microgrids are infrastructure elements that bridge the gap between emerging energy technologies and the existing power system. Simply put, smart grid objectives including higher penetration of renewables, integration of storage, delivery efficiency improvements, more responsive system elements, stronger resiliency, and improved flexibility will be difficult to achieve without microgrids. The simulation environment developed and the power management methodology presented are important steps towards enabling microgrids and realizing their benefits.

▼ Distributed generation (DG) has been reincarnated after its demise by centralised generation. While economy of scale and efficiency are the advantages of the latter, deregulation of the electricity market, environmental concerns and the need to arrest dwindling reserve margins have necessitated the rebirth of the former. Indeed, a full circle has therefore evolved with generation being ‘embedded’ in distribution systems and ‘dispersed’ around the system rather than being located and dispatched centrally or globally. This development is in tandem with the history of industrial revolutions that started from energy and moved through services and communication and back to energy. South Africa is not immune to the global energy, especially tertiary energy, challenge phenomenon. At the peak of the 2007-2008 energy crisis, her generation net reserve margin fell below 10% – well below conventional industry benchmark of at least 15%. Also South Africa is Africa’s largest emitter of CO2 contributing over 40% of Africa’s total CO2 emissions. Therefore, DG’s relevance to South Africa is quite obvious. However, DG integration into distribution networks leads to a number of challenges. For instance, with significant penetration of DG power flow reversal may be experienced and the distribution network will no longer be a passive circuit. This underscores the crucial role of ICT in active distribution network occasioned by DG and especially the emergent of “prosumerism” (a hitherto consumer also becoming a producer). Therefore, a smart grid and similar phrases have all been used to describe a “digitised” and intelligent version of the present-day power grid. There are immense benefits derivable from modelling and simulation. Consequently, a typical radial distribution network model has been developed to evaluate the considerable impacts of DG integration. The modelling and simulation of the network are accomplished using the DIgSILENT PowerFactory simulation package. Impacts of DG on voltage profile, fault level, voltage stability and protection coordination have been investigated and their possible mitigation measures proferred. The results reveal that for a particular DG type its impacts depend mainly on its capacity and point of connection relative to a given load type. Smart grid technology addresses some of these impacts through its inherent capability which includes peer-to-peer relay communication for protective devices on the distribution feeder as well as communication to the DG facility.
