Este libro es una traducción al idioma español de la obra original “Prabha Kundur: Power System Stability and Control. McGraw-Hill, 1994, ISBN 0-07-035958-X. El Profesor Kundur ha reunido en su libro material sobre estabilidad y regulación de sistemas de potencia proveniente de muchas fuentes, a saber, de cursos para graduados que él ha dictado en la Universidad de Toronto desde 1979, de varios de sus proyectos de investigación desarrollados en vinculación con el Instituto para Investigaciones en Potencia Eléctrica (EPRI), y de un vasto número de sus artículos técnicos publicados por las Instituciones IEEE, IEE y CIGRE. Este libro tiene la intención de satisfacer las necesidades de ingenieros afectados a actividades prácticas en la industria proveedora del servicio eléctrico de utilidad pública, como así también tiende a satisfacer las necesidades de estudiantes universitarios y de investigadores. Este libro aborda la problemática de estabilidad y regulación de sistemas de potencia, proveyendo los fundamentos necesarios, explicando los aspectos prácticos y dando un tratamiento integrado a los últimos desarrollos en técnicas de modelado y a las herramientas analíticas. El libro está dividido en tres partes. La Parte I provee en dos capítulos información sobre el marco de soporte general del libro. El Capítulo 1 describe la estructura de sistemas de potencia modernos e identifica diferentes niveles de regulación. El Capítulo 2 introduce el problema de estabilidad y provee conceptos básicos, definiciones y la clasificación del problema de estabilidad. La Parte II del libro, comprendiendo los Capítulos 3 a 11, está dedicada a las características y al modelado del equipamiento. La estabilidad del sistema es afectada por las características de cada elemento mayor del sistema de potencia, esto es, por las características de cada elemento del sistema de potencia juzgado como el más grande en tamaño o en importancia con respecto a sus semejantes. El conocimiento de las características físicas de los elementos individuales y de sus capacidades es esencial para la comprensión de la estabilidad del sistema. La representación de estos elementos por medio de apropiados modelos matemáticos es crítica para el análisis de estabilidad. Los Capítulos 3 a 10 están dedicados a generadores, a sistemas de excitación, a fuentes primarias de fuerza motriz, a transmisión en corriente alterna (ac) y en corriente continua (dc) y a cargas del sistema. El Capítulo 11 describe los principios de regulación para potencia activa y para potencia reactiva y desarrolla modelos para el equipamiento de regulación. La Parte III, comprendiendo los Capítulos 12 a 17, considera diferentes categorías de estabilidad de sistemas de potencia. El énfasis está puesto en la comprensión física de las muchas facetas del fenómeno de estabilidad. En detalle se describen métodos de análisis junto con medidas de regulación para mitigar los problemas de estabilidad. Las nociones de estabilidad de sistemas de potencia y de regulación de sistemas de potencia están estrechamente relacionadas. Los medios de regulación con influencia sobre el equipamiento en un sistema de potencia están muy distribuidos en una estructura jerárquica. La estabilidad del sistema es fuertemente influenciada por esos medios de regulación. En cada capítulo se ha elaborado la teoría desde puntos de partida sencillos y se la ha desarrollado gradualmente en modo tal que pueda ser aplicada a situaciones prácticas complejas. Esto es suplementado por un gran número de ejemplos ilustrativos. En cualquier parte del libro que resulta apropiado se ponen de relieve perspectivas históricas y experiencias pasadas.

Power System Oscillations deals with the analysis and control of low frequency oscillations in the 0.2-3 Hz range, which are a characteristic of interconnected power systems. Small variations in system load excite the oscillations, which must be damped effectively to maintain secure and stable system operation. No warning is given for the occurrence of growing oscillations caused by oscillatory instability, since a change in the system's operating condition may cause the transition from stable to unstable. If not limited by nonlinearities, unstable oscillations may lead to rapid system collapse. Thus, it is difficult for operators to intervene manually to restore the system's stability. It follows that it is important to analyze a system's oscillatory behavior in order to understand the system's limits. If the limits imposed by oscillatory instability are too low, they may be increased by the installation of special stabilizing controls. Since the late 60s when this phenomena was first observed in North American systems, intensive research has resulted in design and installation of stabilizing controls known as power system stabilizers (PSS). The design, location and tuning of PSS require special analytical tools. This book addresses these questions in a modal analysis framework, with transient simulation as a measure of controlled system performance. After discussing the nature of the oscillations, the design of the PSS is discussed extensively using modal analysis and frequency response. In the scenario of the restructured power system, the performance of power system damping controls must be insensitive to parameter uncertainties. Power system stabilizers, when well tuned, are shown to be robust using the techniques of modern control theory. The design of damping controls, which operate through electronic power system devices (FACTS), is also discussed. There are many worked examples throughout the text. The Power System Toolbox© for use with MATLAB® is used to perform all of the analyses used in this book. The text is based on the author's experience of over 40 years as an engineer in the power industry and as an educator.

Robust Control in Power Systems deals with the applications of new techniques in linear system theory to control low frequency oscillations in power systems. The book specifically focuses on the analysis and damping of inter-area oscillations in the systems which are in the range of 0.2-1 Hz. The damping control action is injected through high power electronic devices known as flexible AC transmission system (FACTS) controllers. Three commonly used FACTS controllers: controllable series capacitors (CSCs) controllable phase shifters (CPSs) and static var compensators (SVCs) have been used in this book to control the inter-area oscillations. The overview of linear system theory from the perspective of power system control is explained through examples. The damping control design is formulated as norm optimization problem. The H_infinity, H2 norm of properly defined transfer functions are minimized in linear matrix inequalities (LMI) framework to obtain desired performance and stability robustness. Both centralized and decentralized control structures are used. Usually the transmission of feedback signal from a remote location encounters delays making it difficult to control the system. Smith predictor based approach has been successfully explored in this book as a solution to such a problem. Robust Control in Power Systems will be valuable to academicians in the areas of power, control and system theory, as well as professionals in the power industry.

A major concern of island power systems is frequency stability. A power system is said to be frequency stable if its generators are able to supply their loads at a frequency within acceptable limits after a disturbance. Frequency instability occurs if load-generation imbalances are not corrected in appropriate manner and time. Since island power systems are more sensitive to frequency instability than large ones due to the smaller number of generators online and the lower inertia, they require a larger amount of primary reserve per generator. This book provides a worldwide overview of island power systems, describing their main features and issues. Split into two parts, the first part examines the technical operation, and in particular, frequency stability of island power systems and its technical solutions, including more efficient underfrequency load-shedding schemes. The chapters explore both conventional and advanced load-shedding schemes and consider the improvement of these schemes by making them more robust and efficient. Advanced devices are modelled and analyzed to enhance frequency stability and reduce the need for load shedding. In the second part, the economic operation of island power systems is explored in detail. For that purpose, regulations and economic operations (centralized vs. market scheme) are reviewed by the authors. The authors discuss models for renewable energy sources and for advanced devices and systems such as demand-side management, energy storage systems, and electric vehicles. This book will be critical reading to all researchers and professionals in power system planning and engineering, electrical/power delivery, RES and control engineering. It will also be of interest to researchers in signal processing and telecommunications and renewable energy, as well as power system utility providers.
