Power conversion and control of wind energy systems

Wind energy is clean and sustainable. It is one of the fastest growing renewable energy resources in the world. Power conversion and control is one of the most important technologies in a wind energy system. It is also a multidisciplinary subject that involves aerodynamics, mechanical systems, electric machines, power electronics, control theory, and power systems. The book covers awide range of topics on wind energy conversion and control from the electrical engineering aspect. It includes wind generators and modeling, power converters and modulation schemes, operating principle of fixed and variable speed wind turbines, advanced generator control schemes, active and reactive power controls of individual wind and is a valuable reference book for academic researchers, practicing engineers, and other professionals. The book can also be used as a textbook for graduate level and final year undergraduate-level courses. INDICE: Preface. List of Symbols. Acronyms and Abbreviations. 1.
