Wind Power in Power Systems

Contributors xxv
University of Denmark, the Institute for Research and Development of the Danish
Electric Utilities, Lyngby, Denmark, and Electricite´ de France, Clamart, France. In
2000 he joined the Department of Transmission and Distribution Planning of the
Danish transmission and distribution company NESA. He works on general network
planning, power system stability and the development of wind turbine simulation
models. Email: JON@NESA.dk
Jonas Persson received an MSc degree in electrical engineering from Chalmers University
of Technology, Go¨ teborg, Sweden, in 1997 and a Tech. Lic. degree in electric power
systems from the Royal Institute of Technology, Stockholm, Sweden, in 2002. He joined
ABB, Va¨ stera˚s, Sweden, in 1995 where he worked on the development of the power
system simulation software Simpow. In 2004 he joined STRI, Ludvika, Sweden, where
he develops and teaches Simpow. Currently, he also works at the Royal Institute of
Technology in Stockholm, Sweden, towards a PhD on bandwidth-reduced linear models
of noncontinuous power system components. Email: Jonas.Persson@stri.se.
Henk Polinder received in 1992 an MSc degree in electrical engineering and in 1998 a
PhD, both from the Delft University of Technology. Currently, he is an associate
professor at the Electrical Power Processing Laboratory at the same university, where
he gives courses on electrical machines and drives. His main research interest is generator
systems in renewable energy, such as wind energy and wave energy. Email:

Uwe Radthe was born in 1948. He received the Doctor degree in Power Engineering
from the Technical University of Dresden in 1980. In 1990 he joined PreussenElektra
and worked in the network planning department. He was involved in international
system studies as project manager and specialist of high voltage direct current transmission
systems. From 2000 until 2003 he worked for E.ON Netz, responsible for system
integration of renewable energy, especially wind power generation.
Harold M. Romanowitz is president and chief operating officer of Oak Creek Energy
Systems Inc. and a registered professional engineer. He holds a BScEE from Purdue
University and an MBA from the University of California at Berkeley. He has been
involved in the wind industry in California since 1985 and received the AWEA Technical
Achievement Award in 1991 for his turnaround work at Oak Creek. He has been
directly involved in efforts to improve the Tehachapi area grid over this time, including
the achievement of a better understanding of the impacts of induction machines and
improved VAR support. In 1992–93 he designed and operated a 2.88 MW 17 280 KWH
battery storage system directly integrated with wind turbines to preserve a firm capacity
power purchase agreement. He was a manufacturer of engineered industrial drive
systems for many years, produced the first commercial regenerative thyristor drives in
the USA and WattMiser power recovery drives. He has extensive experience with
dynamic systems, including marine main propulsion (10 MW), large material handling
robots, container and bulk-handling cranes, large pumps and coordinated process lines.
