M. HASHEM NEHRIR, PhD, is a Professor of Electrical and Computer Engineering at Montana State University-Bozeman. His primary areas of interest include modeling and control of power systems, alternative energy power generation systems, and applications of intelligent controls to power systems. In addition to this book, he is the author of two textbooks and the author or coauthor of numerous technical papers. He is a member of the IEEE PES Energy Development and Power Generation Committee and currently is Vice Chair of the IEEE PES Energy Development Subcommittee.CAISHENG WANG, PhD, is Assistant Professor at Wayne State University in Detroit, Michigan. He has worked in the areas of both large power systems and distributed generation systems, including alternative energy sources. As a part of his doctoral research, during 2002-2006, Dr. Wang was involved in fuel cell modeling and control and design of hybrid alternative energy power generation sources, including fuel cells.
