Resumo: O conceito de estabilidade a tempo finito (ETF) foi criado em 1950. Sistemas dinâmicos cujas trajetórias convergem para o estado de equilíbrio em um tempo finito fazem parte desse conceito. Sistemas chaveados lineares não homogêneos também estõ sendo considerados. Esses sistemas são oriundos de muitas aplicações de controle e para casos aonde sistemas físicos não são descritos por processos unicamente contínuos ou unicamente discretos. Essa dissertação esta concentrada no problema de estabilidade a tempo finito de uma classe de sistemas chaveados lineares não homogêneos contínuos no tempo sob um sinal de chaveamento dependente do tempo seguindo um tempo de permanência T. Uma vez que a estabilidade a tempo finito é garantida, um dos principais resultados dessa dissertação garante que qualquer trajetória do sistema que comece em uma região 1 do espaço de estados, permanecera dentro de 2 _ 1 ao longo de um intervalo de tempo finito, e para qualquer sequencia de chaveamento com tempo de estabelecimento ¯ T _ T. As condições de estabilidade a tempo finito obtidas na forma de inequações matriciais bilineares (BMIs), podem ser transformadas em inequações matriciais lineares (LMIs) por uma sequência de passos que incluem o cálculo dos conjuntos 1 e 2 por meio de um conhecimento prévio dos limites de operação do sistema. Dois exemplos ilustrativos do estudo de estabilidade em sistemas de potência são utilizados para apresentar a validade dos resultados. Palavras-chave: estabilidade a tempo finito, sistemas chaveados não autônomos, inequações matriciais lineares
Abstract: The finite-time stability (FTS) concept was created in the 1950. Dynamical systems whose trajectories converge to an equilibrium state in finite time are involved in this concept. Switched non-homogeneous linear systems are being considered. These systems can result from many control applications and for cases where physical systems are not described by simply continuous or simply discrete processes. This dissertation is concerned with the finite-time stability problem of a class of linear continuous-time non-homogeneous switched systems under a time-dependent switching signal constrained by a dwell-time T. Once the finite-time stability is guaranteed, one of the main results of the dissertation guarantees that any system trajectory starting in a subset 1 of the state-space will remain in 2 _ 1 over a finite time interval, and, for any switching sequence with a dwell-time ¯ T _ T. The finite-time stability conditions which provided in the form of bilinear matrix inequalities (BMIs), can be transformed to linear matrix inequalities (LMIs) by means of a step-by-step procedure that includes the computation of the sets 1 and 2 by the knowledge of the system's operating range. Two illustrative examples in power system stability study are used to show the validity of the results. Keywords: finite-time stability, Non-autonomous switched systems, Linear matrix inequalities

Pełny tekst źródłaLarge increases in the complexity of shipboard electric loads as well as development of electric drive, integrated electric drive and pulsed power systems make manifest the present and future importance of naval electric power systems. The most crucial attribute of these systems is their ability to fulfill their function in the presence of "large-signal" perturbations. Fundamental differences between shipboard and commercial electric power systems make all but the most general nonlinear, "large-signal" stability analyses inappropriate for the design and assessment of naval electric power systems. The tightly coupled and compact nature of shipboard systems are best accommodated by composite system stability analyses. Composite system methods, based upon Lyapunov's direct method, require that each component's stability be represented by a Lyapunov function. A new Lyapunov function which is based upon coenergy is developed for 3-phase synchronous machines. This use of coenergy is generalizable to all electromechanical energy conversion devices. The coenergy-based Lyapunov function is implemented as a "stability organ" which generates waveforms at information teirninals of a "device object" in the object oriented simulation environment of WAVESIM. Single generator simulation results are used to acquire a measure of the "over sufficiency" of the coenergy-based Lyapunov function. Some means of combining the components' Lyapunov functions is necessary with composite system stability criterions. To provide the largest stability region in a Lyapunov function convective derivative space, thereby reducing "over sufficiency", a "timevariant weighted-sum" composite system criterion is developed. This criterion is implemented as a "stability demon" "device object" within the WAVESIM environment. The "stability demon" is tested through RLC circuit simulations and a two-generator simulation. The output of the "stability demon" is suitable for use within an overall system stabilising controller.

Pełny tekst źródłaLa irrupción de fuentes de energía renovables como la energía solar fotovoltaica está transformando los sistemas eléctricos. Para minimizar los posibles efectos adversos sobre la red eléctrica de los sistemas de generación conectados mediante convertidores de electrónica de potencia, los operadores de los sistemas eléctricos definen diferentes estrategias y exigen que todos los sistemas conectados a la red cumplan diferentes normas. Con el objetivo de permitir una mejor integración de estas fuentes renovables, se han propuesto varios controladores de convertidores de potencia que intentan reproducir algunas características de las máquinas síncronas convencionales. Esta tesis trata sobre el análisis del impacto que las centrales eléctricas de grandes dimensiones basadas en electrónica de potencia tienen en la estabilidad de los sistemas eléctricos. En primer lugar, se clasifican estos controladores avanzados, lo que permite realizar una comparación detallada de varios aspectos relacionados con su implementación y su dinámica. Las propuestas más comunes se comparan en cuanto a su necesidad de sistemas de sincronización auxiliares, su habilidad para energizar una red, o su efectividad a la hora de limitar la corriente inyectada durante una falta y mantener los convertidores conectados a la red. Además, se realizan y analizan simulaciones de la respuesta de convertidores de potencia que utilizan estos controladores. A continuación, se presenta el modelado de una planta fotovoltaica real de 100 MW formada por 100 convertidores de potencia, considerando su equivalente monofásico para estudios de estabilidad transitoria en sistemas equilibrados. Este modelo incluye los terminales, cables y transformadores de la red interna, así como los convertidores de potencia con sus sistemas de control y recursos primarios. Además, el modelo está diseñado de manera flexible, permitiendo considerar controladores convencionales o controladores de potencia síncronos, y el recurso fotovoltaico se puede sustituir por un sistema de almacenamiento. Adicionalmente, se desarrolla un método para calcular un modelo equivalente de las centrales eléctricas que utilizan esta clase de controladores avanzados y se obtienen tres modelos equivalentes de la planta, con distintos niveles de detalle. Estos modelos permiten reducir la complejidad del modelo original y su carga computacional asociada, al mismo tiempo que reproducen su dinámica con precisión, haciéndolos más adecuados para el análisis de sistemas eléctricos con un gran número de unidades de generación, cargas, elementos pasivos y controladores. Finalmente, se analiza la estabilidad de sistemas eléctricos que integran este tipo de plantas generadoras. Se lleva a cabo un primer análisis en un sistema de pruebas de doce barras, considerando un modelo más sencillo de la planta donde las características fotovoltaicas se modelan únicamente mediante una limitación de la potencia activa, y se compara el impacto de estas plantas en distintos escenarios con una penetración solar creciente, llegando a un nivel del 50% de la generación total. Después, se analiza el Sistema Interconectado del Norte Grande de Chile, teniendo en cuenta la situación real de la planta modelada previamente e incluyendo el recurso fotovoltaico en detalle. Por último, se evalúa el impacto que pueden tener las plantas híbridas formadas por un generador síncrono y un sistema fotovoltaico, con diferentes configuraciones con la posibilidad de reservar parte de la producción solar o utilizar un sistema de almacenamiento. Estos análisis comprenden el estudio tanto de los valores propios del sistema como de su respuesta a diferentes tipos de eventos mediante simulaciones en el dominio del tiempo, y demuestran la capacidad de los controladores estudiados para incrementar el amortiguamiento del sistema, reducir las oscilaciones a las que se ven sometidos otros generadores y limitar las máximas desviaciones de frecuencia.
