▼ L'Internet des objets (IoT, pour Internet of Things, en anglais) ouvre la porte vers la réalisation de nouvelles applications, telles que les compteurs intelligents et le suivi environnemental, destinées à adresser nos défis sociétaux et écologiques actuels et futurs. Les objets, possiblement mobiles ou distants, nécessitent une connectivité sans fil pour la centralisation des données et le contrôle à distance. Les réseaux longue portée et basse consommation (LPWA, pour Low Power Wide Area, en anglais) offrent des transmissions radio bande étroite avec une couverture à l’échelle typique d’une ville, tout en respectant les contraintes de consommation énergétique bas coût des objets. Intégrer la possibilité de localiser ces objets ajouterait de la valeur à leurs données et permettrait leur suivi géographique. Voilà pourquoi c'est un domaine de recherche très actif actuellement. L'utilisation du temps de propagation des signaux radio de communication, sans intégration supplémentaire de modules matériels dédiés à la localisation, est une approche très intéressante pour la complexité, la consommation et le coût des objets. Néanmoins la radio localisation dans les réseaux LPWA pose des défis liés d'une part aux transmissions à bande étroite qui n'offrent pas une résolution temporelle suffisante et d'autre part aux canaux de propagation qui peuvent introduire des biais sur les estimées de position. Cette thèse adresse ces défis en étudiant un système de mesure multicanaux de distance pour les réseaux LPWA. La combinaison cohérente des signaux bande étroite transmis séquentiellement sur des canaux différents améliore la précision d’estimation des temps de propagation et permet de résoudre en partie les multi-trajets pour une meilleure précision de localisation. Cette technique basée sur les signaux à bande instantanée étroite conserve la capacité longue portée des transmissions et reste compatible avec les réseaux LPWA. Un modèle détaillé prenant en compte les imperfections matérielles ainsi que les besoins protocolaires pour la synchronisation en temps, fréquence et phase est développé. Basé sur ce modèle, les variantes des architectures des émetteurs-récepteurs radios et leurs impacts sur la cohérence de phase pour l’estimation multicanaux de distance sont discutés. Les limites théoriques de précision sont dérivées pour la propagation en espace libre et dans des canaux de propagation multi-trajets, illustrant l’amélioration de précision possible entre l'approche multicanaux et l'approche monocanal pour l'estimation de distance. Des estimateurs de distance sont développés et appliqués aux signaux radio simulés afin de montrer que leurs performances atteignent les limites théoriques. Ces résultats de simulation sont validés avec des expérimentations menées avec un démonstrateur implémenté avec une radio logicielle (SDR, pour Software Defined Radio, en anglais). Les tests terrains réalisés en environnement urbain permettent de confirmer l'apport d'un système d'estimation multicanaux de distance, en combinaison avec du… Advisors/Committee Members: Cances, Jean-Pierre (thesis director), Meghdadi Neyshabouri, Vahid (thesis director), Rivaz, Sebastien de (thesis director).

Depuis les 20 dernières années, l'essor de l'IoT et du "cloud computing" a conditionné le besoin dedéployer massivement, et globalement, des capteurs afin d'alimenter des bases de données et améliorerla précision des algorithmes d'analyse. Pour répondre à ces demandes, de nouveaux réseaux basés surles bandes de fréquences ISM ont été déployés. Nous avons donc appréhendé de façon complète cestechnologies afin de garantir une qualité maximale pour nos produits mais aussi proposer des conseilsjustes dans un secteur ou abus de langage et promesses de performances sont monnaie courante.Cependant, le nombre grandissant d'objets émettant sous la fréquence du gigahertz lève un doutequant à l'impact sur la santé des êtres vivants. Dès lors, coupler l'aspect non invasif des VLC avecl'Internet des Objets permettrait non seulement de réduire les risques pour les êtres humains maisaussi de limiter la saturation des bandes radio.Néanmoins, les techniques d'aujourd'hui consistent principalement en la réalisation de systèmesdiffusant l'information depuis une source unique vers plusieurs récepteurs, ce qui est l'inverse du paradigmede l'IoT. Dans cette étude, nous avons donc réalisé un nouveau design basé sur les VLC qui meten place une topologie de réseau en étoile 3. Ce système, basé sur un concentrateur disposant d'une ouplusieurs caméra en guise de photo-récepteurs, est optimisé pour plus d'autonomie. Ainsi, la vitessede transmission peut être gérée dynamiquement sans être connue par les autres éléments du système.

In the last 20 years, the coming up of Internet of Things and Cloud Computing has conditionedthe need to deploy sensors everywhere to feed databases and analytics. To meet this requirements,new kind of networks have been massively deployed based on the sub-gigahertz frequency which haveunknown effect on human health.Couple the non-invasive aspect of the Visible Light Communication (VLC) with IoT could notonly reduce potential risks for human health but also avoid radio band saturation. However, today'stechniques consist mainly in broadcast data from light sources to receivers which is the opposite of theIoT paradigm. In this study, we will present a new design where the gateway is not a classic photodiodebut a camera.With this camera based method, we are able to design a star network using VLC. Even if the datarate is not the same as standard method, we are now able to collect data emanating from many sensorsat once with only one photoreceptor. This system also includes the ability of discriminate LED matrix,which transfer the same data faster, and single LED. Finally, data rate can be handle autonomouslyby the system to provide an optimal data transfer.

Low Power Wide Area Networks (LPWAN) são candidatas a coexistir com as redes celulares tradicionais por lidar com diferentes tipos de requisitos como densidade, confiabilidade e latência. Entretanto, não existe uma tecnologia LPWAN que consiga atender todas as necessidades das aplicações de Internet das Coisas (IoT). Por essa razão, a integração de diferentes tecnologias LPWAN se faz necessária, criando assim, uma rede LPWAN heterogenia. SDN fornece uma abordagem poderosa, criando uma arquitetura programável, dinâmica e flexível. Alguns estudos já investigam a aplicação do paradigma SDN para fornecer uma rede programável para aplicações IoT. No entanto, esses estudos não levam em consideração a capacidade limitada dos dispositivos de rede baseados em SDN para armazenar as regras de encaminhamento. Nesta dissertação é proposto HELPFUL, uma arquitetura baseada nos conceitos definidos pelas Redes Definidas por Software (SDN) que cria uma abstração comum entre diferentes tecnologias LPWAN que rodam sobre estações base virtualizadas. Nós também discutimos quatro estratégias de gerenciamento de regras para serem utilizadas com HELPFUL, provendo suporte para uma única ou múltiplas tabelas. Nós avaliamos nossa proposta com uma serie de experimentos com protótipo desenvolvimento utilizando a linguagem P4. Os resultados mostram que HELPFUL é flexível o suficiente para que a estratégia de gerenciamento de regras na tabela de fluxos seja alterada para melhor se adequar as necessidades da rede. Consequentemente, HELPFUL reduz a quantidade de mensagens no canal de controle trocadas pelos controlador e gateway. Finalmente, HELPFUL adiciona uma sobrecarga mínima ao desempenho da rede independente da estratégia escolhida.

Low Power Wide Area Networks (LPWAN) are candidates to coexist with traditional cellular networks by coping with different types of requirements such as density, reliability, and latency. However, there is no one-size-fits-all technology that can address all the needs of IoT applications. For this reason, the integration of heterogeneous LPWAN becomes necessary. SDN provides a powerful approach by creating a programmable, dynamic, and flexible architecture. Some studies investigate the SDN paradigm to provide a programmable network to IoT applications. Nevertheless, these studies do not take into account the limited capacity of SDN-based networking devices to store the forwarding rules in its architectures. This thesis presents the HELPFUL, an SDN-based architecture that creates a common control abstraction among LPWAN technologies (e.g., LoRa, NB-IoT) running on top of virtualized base stations. We also discuss four rule management strategies for use with HELPFUL, providing support for single and multiple tables. We evaluate our proposal with a series of experiments with a prototype developed using the P4 language. Results show which HELPFUL is flexible enough to change the management strategy to the best fit with the network demands. Consequently, it can reduce the number of messages on the control channel…

▼ The widespread of Internet connection, particularly on small devices (embedded systems), has allowed the development of the Internet of Things (IoT) concept, due to the connection of these devices to web micro services (Cloud), and has had a major role in Industry 4.0 [1]. Through the advances of wireless technologies, these devices were able to have an Internet connection, becoming available everywhere. The creation of Wireless Sensor Networks (WSNs) has enabled the use of networks composed of independent devices (nodes or edge devices), equipped with sensors and actuators, and made it possible to collect information about the environment where they are deployed [2]. The growing necessity of having a wider coverage area for Wireless Sensor Networks, along with the demanding low power requirements on devices has enabled Low Power Wide Area (LPWA) technologies to arise. These technologies are able to reach further coverage than conventional wireless technologies (such as Bluetooth, Wi-Fi, ZigBee etc), as well as raising the energy autonomy of the devices [3], which makes LPWA technologies ideal for wider areas. The recent tragedies of wildfires in Portugal, in both 2017 and 2018, had great impact on economic and social levels. Early detection and alerts about wildfires are crucial to prevent them from spreading [4]. Therefore, by using LPWA technologies in forests, a case study can be made for the wildfire occurrences in forests. Through the use of independent devices equipped with sensors, data can be collected from the environment that might detect that a fire is starting, and then send alerts to fire fighting units. In this Master’s thesis it was developed the architecture of sensor nodes, to be integrated in a Low Power Wide Area Network (LPWAN). By using the LoRa technology to achieve a long range between the sensor nodes and the network coordinator, it is possible for edge devices to collect and send data to upper levels of the network. It was possible to gather information about the environment and further understand LoRa’s potential for sending all the data to the upper levels of the network.

Abstract The Internet of Things (IoT) is already providing solutions to various tasks related to monitoring the environment and controlling devices over wired and wireless networks. It is estimated by several well-known research facilities that the number of IoT devices will be in the order of tens of billions by 2020. This inevitably brings challenges and costs in deployment, management, and maintenance of networks. The focus of this thesis is to provide solutions that mainly help in the deployment and maintenance of various wireless IoT networks. Different applications have different requirements for a wireless link coverage. It is important to utilize suitable radio technology for a particular application in order, e.g., to maximize the lifetime of a device. A wireless body area network (WBAN) typically consists of devices that are within couple of meters from each other. The WBAN is suitable for, e.g., measuring muscle activity and transferring data to a storage for processing. The wireless link can use air as a medium, or alternatively, an induced electric field to a body can be used. In this thesis, it is shown that a location of the electrodes in the body have impact to the attenuation. Home automation IoT applications are typically implemented with mid-range wireless technologies, known as wireless personal area networks (WPAN). In order to minimize and get rid of battery change operations, a wake-up receiver could be utilized in order to improve the device’s energy efficiency. The concept is introduced and performance of the current state-of-the-art works are presented. In addition, a control loop enabling a passive device to have control over an energy source is proposed. Applications that have low bandwidth requirements can be implemented with low-power wide area networks (LPWAN).

Usea hyvin tunnettu tutkimusorganisaatio on arvioinut, että vuonna 2020 IoT laitteiden määrä tulee olemaan kymmenissä miljardeissa. Se luo väistämättä haasteita laitteiden sijoittamisessa, hallinnassa ja kunnossapidossa. Tämä väitöskirja keskittyy tarjoamaan ratkaisuja, jotka voivat helpottaa langattomien IoT laitteiden sijoittamisessa ja kunnossapidossa. IoT sovellusten laaja kirjo vaatii erilaisia langattomia radioteknologioita, jotta sovellukset voitaisiin toteuttaa, muun muassa, mahdollisimman energiatehokkaasti. Langattomassa kehoverkossa (wireless body area network, WBAN) käytetään usein hyvin lyhyitä langattomia linkkejä. WBAN on soveltuva esimerkiksi lihasten aktiivisuus mittauksessa ja mittaustiedon siirtämisessä talteen varastointia ja prosessointia varten. Linkki voidaan toteuttaa käyttäen ilmaa rajapintana, tai vaihtoehtoisesti, kehoa. Tässä työssä on näytetty, että…

▼ One of the main concerns for the secure and reliable operation of power systems is the small signal stability problem. In the complex and highly interconnected structure of future power systems, relying solely on operator responses and conventional controls cannot assure reliability. Therefore, there is a need for advanced Wide-Area Control Schemes (WACS) that can automatically respond to degradation of reliability in the system. The main objective of this dissertation is to address two key challenges regarding the design and implementation of wide-area control schemes for damping inter-area oscillations. First is the high communication cost associated with optimal centralized control approaches. As power networks are large-scale systems, both the synthesis and the implementation of centralized controllers suggested by most of the previous studies are often impossible in practice. Second is the difficulty of obtaining accurate system-wide dynamic models for initiating and updating the control design. In this research, we introduced wide-area damping control strategies that not only ensure the small signal stability with the desired performance but also consider communication and model information limitations in the design. A state feedback formulation is proposed that aims to simultaneously optimize a standard Linear Quadratic Regulator (LQR) cost criterion and induce a pre-defined communication structure. We solved the proposed problem with three different objectives to target a specific wide-area damping control design challenge in each setting. First, the communication structure is enforced as a constraint in the optimization and solved for a large idealized power network with information symmetry. Second, to make the method suitable for systems with arbitrary structures and information patterns, we proposed a group-sparse regularization to be added to the optimization cost function. Applications of the method for inducing the desired communication network and finding effective measurement and control signal combinations were also investigated. Third, we paired the proposed optimal control with a real-time model identification approach, to create a wide-area control framework that is capable of dealing with model information limitations and inaccuracies in online implementation. The performances of the proposed wide-area damping control architectures are validated through nonlinear simulations on different test systems.

▼ Renewable energy sources have been extensively developed in many countries like United Kingdom and academia like enhanced frequency control capability (EFCC) project in the last decades due to environmental and energy security risks, however, the system inertia is decreased and frequency response imposes a new challenge for power system operators to maintain power quality. Additionally, restricting RoCoF within satisfactory restrictions is so critical to prevent triggering protection relays that can result in cascaded problems and violate system security. The inertial response (IR) and droop based primary frequency response (PFR) using available spinning reserve power are inherently deployed in conventional power plants (CPPs) to restore sudden frequency deviations. However, power converter interfaces decouple the network frequency from the rotational part of wind energy conversion systems (WECS). In addition, the photovoltaic (PV) units have static dc generators. Thus, these generating units, by themselves, neither obtain the IR nor participate in PFR mechanism. A faster and smarter frequency response is required in order to compensate this phenomenon. The objective of the research presented in this thesis is to derive the local and wide-area smart frequency control based wide-area monitoring system (WAMS) supported by PMU-based local and wide-area monitoring systems, which is able of releasing fast, smart and robust primary frequency response from fast service providers like combined cycle gas turbine (CCGT), WECS, PV, battery energy storage (BES) and smart induction motors (SIMs). The research proposed in this thesis includes the creation of a novel robust process for the on-line estimation of loss of generation considering load damping impact, PMU latency and implausible spike in frequency data. Furthermore, the CCGT dynamic behaviour is accurately modelled and their unique fast frequency response following the frequency excursions is investigated. This research study also proposes a new wind unit control architecture based on inertial emulator and pitch controller to enhance its frequency response for its high integration in large-scale power systems. The novelty lies in the technique to defining the reference injection power from a control structure based on the novel maximum power point tracking (MPPT) surface deploying rotor speed and pitch angle which doesnâ€™t rely on wind speed information. Additionally, the accurate drive train aerodynamic equations of wind turbine are also implemented beside the double-mass mechanical dynamics to investigate the oscillation frequency of electromechanical eigenvalues. Furthermore, a PV and vanadium redox BES enhanced with the control framework to provide primary frequency control, suitable for large scale frequency studies are provided. In case of PV, a primary controller is introduced which permits droop-control operation at deloaded MPPT based on available reserve power and emulated inertial power capturing from dc link capacitor by adjusting the dc link reference… Advisors/Committee Members: MUTALE, JOSEPH J, Terzija, Vladimir, Mutale, Joseph.

▼ 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.

▼ 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.

▼ 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.

▼ Wide-area measurement systems (WAMS) are quickly becoming an important part of modern power system operation. By utilizing the Global Positioning System, WAMS offer highly accurate time-synchronized measurements that can reveal previously unobtainable insights into the grid’s status. An example WAMS is the Frequency Monitoring Network (FNET), which utilizes a large number of Internet-connected low-cost Frequency Disturbance Recorders (FDRs) that are installed at the distribution level. The large amounts of data collected by FNET and other WAMS present unique opportunities for data mining and machine learning applications, yet these techniques have only recently been applied in this domain. The research presented here explores some additional applications that may prove useful once WAMS are fully integrated into the power system. Chapter 1 provides a brief overview of the FNET system that supplies the data used for this research. Chapter 2 reviews recent research efforts in the application of data mining and machine learning techniques to wide-area measurement data. In Chapter 3, patterns in frequency extrema in the Eastern and Western Interconnections are explored using cluster analysis. In Chapter 4, an artificial neural network (ANN)-based classifier is presented that can reliably distinguish between different types of power system disturbances based solely on their frequency signatures. Chapter 5 presents a technique for constructing electromechanical transient speed maps for large power systems using FNET data from previously detected events. Chapter 6 describes an object-oriented software framework useful for developing FNET data analysis applications. In the United States, recent environmental regulations will likely result in the removal of nearly 30 GW of oil and coal-fired generation from the grid, mostly in the Eastern Interconnection (EI). The effects of this transition on voltage stability and transmission line flows have previously not been studied from a system-wide perspective. Chapter 7 discusses the results of power flow studies designed to simulate the evolution of the EI over the next few years as traditional generation sources are replaced with greener ones such as natural gas and wind. Conclusions, a summary of the main contributions of this work, and a discussion of possible future research topics are given in Chapter 8.

▼ Les progrès des technologies de communication à faible consommation d’énergie et à faible cout ont révolutionne les applications de télédétection et de surveillance. L’Internet des objets (IoT) a promis la création d’un écosystème d’appareils connectes à travers un large éventail d’applications, telles que les villes intelligentes. A l’heure actuelle, de nombreuses normes et technologies concurrentes tentent de saisir l’IoT, en particulier dans le domaine des technologies de télédétection et de communication. LoRa (Long Range) est l’une de ces technologies qui gagne en popularité et en attraction dans les réseaux de capteurs sans fil (WSN). La possibilité d’établir des communications longue distance avec des nœuds relativement simples, une infrastructure minimale, des besoins en énergie réduits et l’utilisation de bandes ISM sans licence offre un avantage concurrentiel significatif. Bien que la portée de communication dans LoRa puisse dépasser 15 kilomètres en visibilité directe, le débit binaire maximal pouvant être atteint est limite à quelques kilobits par seconde. De plus, lorsqu’une collision se produit dans LoRa, le débit est encore réduit en raison de pertes de trames et de retransmissions. Les travaux de cette thèse traitent le problème des collisions dans LoRa qui peuvent survenir sous une charge importante et qui dégradent les performances du réseau.Premièrement, nous considérons le contexte des communications en liaison montante dans LoRaWAN. Nous étudions le contexte des signaux LoRa en collision synchronisée, ou chaque appareil terminal doit retransmettre toute sa trame en collision après qu’une collision se produit dans LoRa. Ce comportement diminue le débit global et augmente la consommation d’énergie des terminaux et le délai des trames. Pour cette raison, afin d’atténuer les effets néfastes des collisions, nous avons proposé un algorithme de décodage pour résoudre les signaux LoRa en collision synchronisée, dans un trafic réseau sature et confirme. Nous avons remplacé le modèle de retransmission conventionnel de LoRa en un modèle faisant en sorte que les dispositifs terminaux transmettent des bitmaps au lieu de retransmettre des trames entières pour déterminer les symboles corrects de chaque trame en collision. Notre algorithme a pu améliorer significativement le débit global de la couche LoRaWAN MAC à base de LoRa, et diminuer la consommation d’énergie des émetteurs et le délai des trames.Deuxièmement, nous considérons le contexte des communications en liaison descendante dans LoRaWAN. Nous avons remarqué que la liaison descendante dans LoRa est un goulot d’étranglements. Nous avons donc travaillé sur la sélection de la passerelle par le serveur de réseau et son impact sur le débit, la consommation d’énergie et le délai. Nous avons étudié trois types de déploiement de passerelle et nous avons montre que les performances du système dépendent de ce déploiement. Nous avons montré que l’équilibrage du nombre de terminaux par passerelle (également connu sous le nom de charge) améliore le débit par… Advisors/Committee Members: Guitton, Alexandre (thesis director), Safa, Haidar (thesis director).

Les systèmes de communication mobiles permettent l’utilisation de l’information en environnements complexes grâce à des dispositifs portables qui ont comme principale restriction la durée de leurs batteries. Des nombreux efforts se sont focalisés sur la réduction de la consommation d’énergie des circuits électroniques de ces systèmes, une fois que le développent des technologies des batteries ne avance pas au rythme nécessaire. En outre, les systèmes RF sont généralement conçus pour fonctionner de manière fixe, spécifiés pour le pire cas du lien de communication. Toutefois, ce scénario peut se produire dans une petite partie du temps, entraînant ainsi en perte d’énergie dans le reste du temps. La recherche des circuits RF adaptatifs, pour adapter le niveau du signal d'entrée pour réduire la consommation d'énergie est donc d'un grand intérêt et de l'importance. Dans la chaîne de réception radiofréquence, l'amplificateur à faible bruit (LNA) se montre un composant essentiel, autant pour les performances de la chaîne que pour la consommation d'énergie. Au cours des dernières décennies, des techniques pour la conception de LNAs reconfigurables ont été proposées et mises en oeuvre. Cependant, la plupart d'entre elles s’applique seulement au contrôle du gain, sans exploiter Le réglage de la linéarité et du bruit envisageant l'économie d'énergie. De plus,ces circuits occupent une grande surface de silicium, ce qui entraîne un coût élevé, ou NE correspondent pas aux nouvelles technologies CMOS à faible coût. L'objectif de cette étude est de démontrer la faisabilité et les avantages de l'utilisation d'un LNA reconfigurable numériquement dans une chaîne de réception radiofréquence, du point de vue de la consommation d'énergie et de coût de fabrication.

Mobile communication systems allow exploring information in complex environments by means of portable devices, whose main restriction is battery life. Once battery development does not follow market expectations, several efforts have been made in order to reduce energy consumption of those systems. Furthermore, radio-frequency systems are generally designed to operate as fixed circuits, specified for RF link worst-case scenario. However, this scenario may occur in a small amount of time, leading to energy waste in the remaining periods. The research of adaptive radio-frequency circuits and systems, which can configure themselves in response to input signal level in order to reduce power consumption, is of interest and importance. In a RF receiver chain, Low Noise Amplifier (LNA) stand as critical elements, both on the chain performance or power consumption. In the past some techniques for reconfigurable LNA design were proposed and applied. Nevertheless, the majority of them are applied to gain control, ignoring the possibility of linearity and noise figure adjustment, in order to save power. In addition, those circuits consume great area, resulting in high production costs, or they do not scale well with CMOS. The goal of this work is demonstrate the feasibility and…

En comparant les performances des systèmes existants à la limite théorique issue de la théorie de l'information et démontrée par Shannon, on constate qu’un gain en performance est atteignable, tout en travaillant toujours à de faibles niveaux de sensibilité. La théorie de l'information permet d'affirmer qu'un compromis entre l'efficacité spectrale et l'efficacité énergétique doit toujours être fait. Ainsi, une haute efficacité énergétique s'obtiendra au détriment d'une efficacité spectrale faible. A l'inverse, un système fonctionnant à une haute efficacité spectrale devra utiliser plus d'énergie pour transmettre le même nombre de bits et atteindre le même taux d'erreur.Ce travail s’intéresse à l’approche faible efficacité spectrale. En partant des modulations orthogonales, qui permettent d’atteindre la limite théorique de Shannon à des efficacités spectrales très faibles, et des processus turbo, qui atteignent d’excellentes performances à des efficacités spectrales élevées, l’utilisation conjointe d’une modulation orthogonale et d'un code correcteur associés à un récepteur itératif dans une technique dénommée Turbo-FSK est étudiée. Les différents paramètres de la technique sont optimisés en utilisant un outil classique des processus itératifs, l’Extrinsic Information Transfer (EXIT) chart. Les performances mesurées démontrent que la technique permet bien d’atteindre de très faibles niveaux de sensibilité et répond aux critères des réseaux longue portée bas débit. Cependant, la technique ne dispose de point de fonctionnement qu’à de très faibles valeurs d’efficacité spectrale : pour certaines applications ou si la portée nécessaire est réduite, il peut être bénéfique pour le système d’augmenter son efficacité spectrale. Ceci est rendu possible grâce à l’introduction d’une composante linéaire dans l’alphabet de modulation et d’un mécanisme de poinçonnage spécifique à la technique dans une version flexible appelée Coplanar Turbo-FSK. L’étude de l’influence des paramètres et des performances sur un canal à bruit blanc additif gaussien permet en effet de conclure sur la flexibilité de l’efficacité spectrale du système, tout en fonctionnant proche de la limite théorique. Finalement, l’étude jusqu’ici théorique est étendue à un contexte plus pratique, où des canaux sélectifs en fréquences sont considérés. Une encapsulation du système utilisant une architecture OFDM est considérée, et différentes mesures caractéristiques des systèmes de télécommunication sont évaluées. Les résultats sont confrontés à la solution Narrow-Band IoT proposée par l’organisme 3GPP et démontrent ici encore le potentiel de la solution Turbo-FSK… Advisors/Committee Members: Ros, Laurent (thesis director), Doré, Jean-Baptiste (thesis director).

▼ This research work investigates the uncertainties in Smart Grid, with special focus on the uncertain wind power generation in wind energy conversion systems (WECSs) and the uncertain wide-area communication in wide-area measurement systems (WAMSs). For the uncertain wind power generation in WECSs, a new wind speed modeling method and an improved WECS control method are proposed, respectively. The modeling method considers the spatial and temporal distributions of wind speed disturbances and deploys a box uncertain set in wind speed models, which is more realistic for practicing engineers. The control method takes maximum power point tracking, wind speed forecasting, and wind turbine dynamics into account, and achieves a balance between power output maximization and operating cost minimization to further improve the overall efficiency of wind power generation. Specifically, through the proposed modeling and control methods, the wind power control problem is developed as a min-max optimal problem and efficiently solved with semi-definite programming. For the uncertain communication delay and communication loss (i.e. data loss) in WAMSs, the corresponding solutions are presented. First, the real-world communication delay is measured and analyzed, and the bounded modeling method for the communication delay is proposed for widearea applications and further applied for system-area and substation-area protection applications, respectively. The proposed bounded modeling method is expected to be an important tool in the planning, design, and operation of time-critical wide-area applications. Second, the real synchronization signal loss and synchrophasor data loss events are measured and analyzed. For the synchronization signal loss, the potential reasons and solutions are explored. For the synchrophasor data loss, a set of estimation methods are presented, including substitution, interpolation, and forecasting. The estimation methods aim to improve the accuracy and availability of WAMSs, and mitigate the effect of communication failure and data loss on wide-area applications.

▼ Over the last decade, power systems have evolved dramatically around the world, owing to higher demand, stringent requirements on quality and environmental concerns that are becoming increasingly critical. With the introduction of new technologies like large-scale renewable energy, wide-area measurement based on phasor measurement units (PMUs) and consumer interaction in the distribution system, the power grid today has become more potent than ever before. Most of the defining features of the smart grid today rest on the integration of advanced communication capabilities into the grid. While communication infrastructure has become a key enabler for the smart grid, it also introduces new and complex control challenges that must be addressed. As we increasingly rely on information transmitted to distant areas over communication networks, it becomes imperative to model the effects of the communication system on the stability of the power grid. Several approaches exist in control theory to study such systems, widely referred to as Networked Control Systems (NCS). Networked control theory provides mathematical tools for system stability analysis and control in the presence of communication delays, packet dropouts and disordering due to transmission of sensor and actuator signals via a limited communication network. In this thesis, a networked control framework for smart grids with integrated commu-nication infrastructure (ICT) is developed. In particular, a networked control systems perspective is developed for two scenarios - wide-area monitoring control, and coordinated control of distributed generation sources. The effects of communication delays and packet dropouts on power system stability are modeled in detail. In the wide-area monitoring control problem, system state measurements are trans-mitted from remote locations through a communication network. The system is modeled as an NCS and a control design approach is presented to damp inter-area oscillations arising from various power system disturbances in the presence of communication constraints. In the coordinated control scenario, a power system with geographically dispersed sources is modeled as an NCS. A networked controller is designed to stabilize the system in the presence of small signal disturbances when system measurements are subject to communication delays and packet dropouts. A realistic output feedback networked control scheme that only uses voltage measurements from PMUs is also developed for practical implementation. The networked controllers designed in this thesis are validated against controllers designed by standard methods, by simulation on standard test systems. The networked controllers are found to enhance power system stability and load transfer capability even in the presence of severe packet dropouts and delays. Several extensions and theoretical problems motivated by this thesis are also proposed. Advisors/Committee Members: Thukaram, D (advisor).

▼ The advent of Wide-Area measurement Systems has spurred interest in the use of non-local feedback signals for power swing damping control. Although damping can be improved through generator excitation systems, dc links and other grid connected power electronic converters, the full potential of wide-area measurements can be realized by coordinating the strategies used for multiple controllable devices in a grid. These strategies also need to be robust to partial or complete loss of communication, changes in operating points, topology and equipment outages, improve damping of all the controllable swing modes, and have adequate stability margins to avoid destabilization of untargeted modes. This thesis investigates a control strategy for multi-infeed and multi-terminal (also referred to as multiple embedded dc links in this thesis) dc links using local frequency difference signals as well as the frequency difference signals obtained from other dc links. This strategy combines the advantages of the local frequency difference signal with the additional degrees of freedom provided by the use of non-local frequency difference signals, to achieve targeted and enhanced swing mode damping for the poorly damped modes. Since the strategy uses only a limited set of non-local signals, the signals may be directly communicated to the dc links without having to be centrally collated with other system-wide measurements. The key aspect of the proposed strategy is the use of a symmetric positive definite (spd) gain matrix. This results in enhanced damping for all controllable swing modes. Furthermore, loss of communication between the dc links does not destroy the symmetric positive definiteness and the gain elements can be tuned to selectively enhance damping of poorly damped modes. Eigenvalue sensitivity analysis and case studies on a 3 machine 9 bus and 16 machine 68 bus system with multiple HVDC links are presented to demonstrate the key attributes and the effectiveness of this strategy.
