Grid Connected Photovoltaic Power Systems

Provides a comprehensive description of the control of grid converters for photovoltaic and wind power systems, enabling effective and reliable grid integration of the power produced. This book provides a detailed coverage of power converters for renewable energy systems, so that power produced from these systems can be efficiently integrated into the national grid. It starts with an overview of the electrical characteristics of renewable energy sources, explaining why it is necessary to interface such sources to the grid through power converters. The authors also cover some general concepts in control theory, explaining different types of controller. Following this, the text goes on to analyse firstly the control of grid converters for photovoltaic, and then wind power systems, looking at system fundamentals, and more specific system control such as maximum point power tracking (MPPT), grid synchronization and monitoring methods, and grid requirement issues. Next, is a more general discussion of grid filters required by grid-connected distributed power generation systems (DPGS), and the interaction between grid converters and the grid. The final chapter examines some new auxiliary functions that may be implemented in DPGS in the future, in order to ensure stability as more power generated by these systems is integrated. Throughout the text, the authors include practical examples, exercises, and simulation models, and an accompanying website sets out further modelling the techniques using Matlab and Simulink environments, and PSIM software. * Provides in-depth coverage of the control and optimization of grid converters for distributed renewable power generation systems (DPGS), focusing on photovoltaic and wind power systems. * Presents a range of control methods for meeting the latest application, power quality and power conversion requirements and standards, as well as looking towards potential future control functions. * Examines grid filter design and the interaction of DPGS with the utility grid. * Includes practical examples, exercises, and an accompanying website with simulation models using Matlab and Simulink environments, and PSIM software.
