Today's electric power systems are continually increasing in complexity due to interconnection growth, the use of new technologies, and financial and regulatory constraints. Sponsored by the Electric Power Research Institute, this expert engineering guide helps you deal effectively with stability and control problems resulting from these major changes in the industry. Power System Stability and Control contains the hands-on information you need to understand, model, analyze, and solve problems using the latest technical tools. You'll learn about the structure of modern power systems, the different levels of control, and the nature of stability problems you face in your day-to-day work. The book features a complete account of equipment characteristics and modeling techniques. Included is detailed coverage of generators, excitation systems, prime movers, ac and dc transmission, and system loads - plus principles of active and reactive power control, and models for control equipment. Different categories of power system stability are thoroughly covered with descriptions of numerous methods of analysis and control measures for mitigating the full spectrum of stability problems. This comprehensive source book is written from a pragmatic point of view, but without undue compromise in mathematical rigor. Filled with illustrative examples, it gives the necessary basic theory and insight into practical aspects.

Voltage stability is a major concern in the planning and operation of electric power systems. This is the first book to provide a clear, in-depth explanation of voltage stability, covering both transient and longer-term phenomena and presenting proven solution to instability problems. An essential tool for all electric power and utility engineers, the book describes equipment characteristics for transmission, generation, and distribution/load subsystems of a power system, together with methods for the modeling of equipment. Readers will find static and dynamiccomputer simulation examples for both small equivalent power systems and for a very large power system, plus an account of voltage stability associated with HVDC links. They will also get helpful planning and operating guidelines, computer methods for power flow and dynamic simulation, and descriptions of actual voltage instability incidents.
