RELIABILITY OF ELECTRIC GENERATION WITH TRANSMISSION CONSTRAINTS by EUGENE GORDON PRESTON An Edited Version Of The DISSERTATION Presented to the Faculty of the Graduate School of the University of Texas at Austin in Partial Fulfillment of the Requirements for the Degree of DOCTOR OF PHILOSOPHY THE UNIVERSITY OF TEXAS AT AUSTIN May 1997 Acknowledgments I would like to thank my advisors, Dr. W. Mack Grady and Dr. Martin L. Baughman, for their support and assistance. Of special importance is the support Dr. Grady provided in the early development of the piecewise quadratic convolution method several years ago. Without the high accuracy provided by the PQ convolution method, the probabilistic load flow model would not have been possible. Recently, Dr. Baughman has been very helpful in reading the drafts and giving advice on the theory and language in this document. I am indebted to Dr. W. C. Duesterhoeft for his support during the development of my Master’s thesis many years ago, and I regret not having completed this dissertation before his untimely death. I am also grateful to the other members of my dissertation committee, Dr. Arwin Dougal, Dr. Paul Jensen, and Dr. Alan Bovik, for their patience and support for the many years I have taken to complete this work. I would like to thank the City of Austin for providing the environment necessary to make this project possible. The real world problems encountered while planning the City’s transmission system greatly influenced my thinking. In particular, my participation on the Electric Reliability Council of Texas Engineering Subcommittee and the Reliability Task Force has been invaluable experience in dealing with real world transmission and generation reliability issues. I also thank the City of Austin for tuition reimbursements and for supporting my travel to meetings, conferences, and short courses on power system reliability topics. I am very thankful to my parents for their loving encouragement,
