Rapid Flexible AC Transmission Systems and Restructured Electrical Power Systems ebooks

Flexible AC Transmission Systems

For many years the electric power industry was characterized by a vertically integrated structure, consisting of power generation, transmission/distribution and trading. The liberalization process has resulted in the unbundling of this organizational structure. Now generation and trading are organized in separate business entities, subject to competition, while the transmission distribution business remains a natural monopoly. Since the trading of electric
energy happens on two levels, the physical level and the contractual level, it has to be recognized that these two levels are completely different. However for understanding the electricity market as a network based industry both levels have to be considered and understood. Electricity cannot be stored in a substantial amount, hence production and consumption have to be matched at each instant of time. Summarizing the current developments, it must be noticed that both planning and operation of electric networks are undergoing fundamental and radical changes in order to cope with the increased complexity of finding economic and reliable network solutions. The operation of the transmission and distribution networks will be closer to their physical limits. The necessity to design electric power networks providing the maximal transmission capacity and at the same time resulting in minimal costs is a great engineering challenge. Innovative operational equipment based on power electronics offers new and powerful solutions.This book is of greatest importance for the practical power engineers for both planning and operational problems. It provides a deep insight into the use of FACTS-devices in modern power systems. Although the technology of modern power electronics will change very quickly, the results presented in this book are sustainable and long lasting.

Restructured Electrical Power Systems

Power engineering is the oldest and most traditional of the various areas within electrical engineering, yet no other facet of modemte chnology is currently undergoing a more dramatic revolution in both technology and industry structure. Worldwided, eregulation, privatization and restructuring have transformed the business and operating context within which the electric power industry must operate. Modem power industry operation is particularly difficult to understand because of the dichotomy between electricity’s business and physical manifestations. From the business perspective, electric power is a fungible commodity, something that can be traded much like oil, wheat, or coffee, and for which futures markets and hedging systems can and do exist. But in its physical manifestation, electricity is quite unlike all other traded commodities. Perhaps the fundamental difference is that it cannot be stored to any significant degree.The net effect of all of these differences is that modemel ectricity trading and wholesale transportation systems are quite different from anything seen previously, either in the electric industry or in any other industry. For this reason, this volume is all the more remarkable, both
for the clarity of its presentation and for the comprehensivwe ayi n which the authors explain how every facet of the industry interacts with and impacts the whole
