In my capacity, as the Editor of this book, first of all I would like to express my
sincere appreciation to the chapter authors for their valuable contributions and
enormous efforts for ensuring the quality of the materials in their chapters. Some
of the results presented in to the book have already been published in international
journals and appreciated in many international conferences and our thanks to those
publishers for giving necessary permission to reuse the materials.

Thanks go to
IEEE Intellectual Property Rights Office, Risø DTU-National Laboratory of Sustainable Energy for assisting authors in various ways.
A large number of individuals including some authors of this book and
organizations have assisted the authors in a variety of ways in the preparation of
this work. In particular, however, we would like to thank Prof.

El-Keib, Dr. Ehab El-Saadany, Dr. Mohd. Hasan Ali,

Dr. Stavros Papathanassiou,
and Dr. S. Dutta for their tremendous support and kind suggestions throughout.
We have made use of Global Wind Energy Council (GWEC), American Wind
Energy Association (AWEA), European Wind Energy Association (EWEA)
publications and record our special thanks to these organizations for making
documents available to us free of charge and sanctioning the permission to use
some of the material therein.

The Editor is grateful to Scaldis Salvage & Marine
Contractors NV for providing few nice pictures used in the Introduction chapter of
the book.
Finally, the Editor wishes to take this opportunity to express his gratitude to

Junji Tamura for valuable suggestions to make this book successful and
tremendous supports since 2002.

Ali Abeidni was born in 1979. He finished his BS., MS. and Ph.D. in IUT, SUT
and UWM respectively.

He joined UW-Madison later as research associate in
2009. Hi is currently a faculty member of Khajeh Nasir Toosi University of
Asger B. Abrahamsen received the Ph.D. degree from the Technical University
of Denmark (DTU) in 2003 for the work on small angle neutron scattering on the
flux line lattice in the superconductor TmNi2B2C done at Risø National Laboratory
in Denmark. He conducted neutron scattering studies of superconductors and
thermo electric materials in a post.doc.

position at the Danish Centre for the use of
Synchrotron X-ray and Neutron facilities (DANSCATT) from 2004-2006. He
continued with in-situ high energy synchrotron scattering examination of the phase
formation of the MgB2 superconductor inside Fe tubes during a second Post.doc.
position from 2006–2007 in the Materials Research Division at Risø National
Laboratory for sustainable energy at the Technical university of Denmark (Risø
DTU). Since 2007 he has been Senior Scientist in the Materials Research Division
at Risø DTU with interest on characterization and applications of superconductors
with special focus on superconducting wind turbine generators.
Ahmed Al-Durra obtained his B.Sc. Eng., M.Sc. Eng, and Ph.D.

in 2005, 2007,
2010, respectively from The Ohio State University. For his Masters, he worked on
the applications of nonlinear control theory to PEM fuel cell systems. During his
Ph.D., he joined the Center of Automotive Research in OSU as a graduate research
assistant, where he worked on model-based estimation and control methodologies
for advance combustion engines.

His research interests are application of estimation and control theory in power system stability, energy storage system (ESS),
and renewable energy.

Presently he is working in Electrical Engineering Department at the Petroleum Institute, Abu Dhabi, U.A.E. Dr. Ahmed is the member of
