Acknowledgments
I started my work on direct methods for power system stability analysis while I was a Ph.D. student at the University of California, Berkeley. The advice I received from my advisors, Felix Wu and Pravin Varaiya, I carry with me to this day. Shankar Sastry’s instruction on nonlinear systems and Leon Chua’s instruction on nonlinear circuits were also very important to my research. In addition, I really appreciate the time Professor Morris Hirsch spent teaching me nonlinear dynamic systems and stability regions. He often spent many hours explaining the world of complex nonlinear phenomena to me, and he was a very inspirational role model.
Several PhD students at Cornell have made significant contributions to the development of the material presented in this book. In particular, I would like to acknowledge Dr. Chia-Chi Chu, Dr. Lazhar Fekih-Ahmed, Dr. Matthew Varghese, Dr. Ian Dobson, Dr. Weimin Ma, Dr. Rene Jean-Jumeau, Dr. Alexander J. Flueck, Dr. Karen Miu, Dr. Chih-Wen Liu, Dr. Jaewook Lee, Mr. Tim Conneen, and Mr. Warut Suampun. Without their hard work, this book would have been incomplete.
Likewise, my former BCU team research associates have made significant contribution to the development of the solution methodologies and the BCU method prototype. I would especially like to acknowledge Dr. Jianzhong Tong, Dr. Chen-Shan Wang, Dr. Yan Zheng, and Dr. Wei Ping. My continual exchange and discussion with Dr. Jianzhong Tong on the general topics of power system dynamic ...
