Short description
Power system risk assessment is becoming an important and mandatory task in planning, operation, maintenance, and asset management of utilities, particularly in the deregulation environment. However, many utilities engineers and managers lack knowledge in this area since it was not a necessary study topic for power engineering students in the past. This book will provide readers with the tools to solve practical problems using appropriate risk assessment techniques. Both analytical and Monte Carlo evaluation methods are discussed with an emphasis on applied techniques and actual considerations in generation, transmission, substation, and distribution systems.
