Bin Wu & Yongqiang Lang 
Power Conversion and Control of Wind Energy Systems [PDF ebook] 

The book presents the latest power conversion and control
technology in modern wind energy systems. It has nine chapters,
covering technology overview and market survey, electric generators
and modeling, power converters and modulation techniques, wind
turbine characteristics and configurations, and control schemes for
fixed- and variable-speed wind energy systems. The book also
provides in-depth steady-state and dynamic analysis of squirrel
cage induction generator, doubly fed induction generator, and
synchronous generator based wind energy systems.

To illustrate the key concepts and help the reader tackle
real-world issues, the book contains more than 30 case studies and
100 solved problems in addition to simulations and experiments. The
book serves as a comprehensive reference for academic researchers
and practicing engineers. It can also be used as a textbook for
graduate students and final year undergraduate students.
