"I highly recommend the essential and very in depth book Power
Conversion and Control of Wind Energy Systems by Bin Wu, Ph.D.,
Yongqiang Lang, Ph.D., Navid Zargari, Ph.D., and Samir Kouro,
Ph.D., to any academics, practicing engineers, consultants,
electrical and energy industry executives, government policy
makers, and graduate and senior undergraduate students seeking a
complete and comprehensive reference textbook that covers all
aspects of wind power conversion and control of wind energy
conversion systems (WECS). This is a landmark book that is a must
for anyone serious about the subject, and about the principles that
underpin wind energy systems." (Blog Business World, 1 March
2012)



"Considering that the wind energy is now highly competitive and
is being emphasized all over the world, this book is extremely
important and very timely. It is expected to be of wide demand in
the world. The book is of unique quality, and no such book
currently exists in the market. The primary emphasis of the book is
power conversion and control of wind energy conversion systems. It
gives comprehensive and in-depth analysis on wind generators, power
converters and control systems of various types of wind generation
systems. There are adequate explanatory materials on different
types of wind turbines, and basics of wind energy systems. The book
is very well-organized with physical explanations, mathematical
analysis, computer simulation, experimental results, and worked-out
examples. There are a large number of worked-out problems at the
end of the book which are extremely important. It is a unique book
with optimal balance of theory and practical discussion. It is a
complete book for designers of wind generation systems and can
serve as textbook for undergraduate/graduate courses in
universities.
