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. The authors 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.
