Oscillatory Stability of Converter-Dominated Power Systems (eBook)

This book provides modeling, analysis, and control methods for wideband oscillations caused by control interactions in converter-dominated power systems. The modern power system comprises power electronic devices in various forms, including wind turbines, photovoltaics, flexible AC/DC transmission systems, battery energy storage systems, and distributed generations, among others. Unstable oscillation modes can cause equipment damage, sudden power reduction, noise in power transformers, and degradation of power quality. Wideband oscillation seriously threatens the stable and reliable operation of wind power systems.

The interaction mechanism becomes more complex due to system-wide factors such as network topology, grid strength, input resource intermittency, converter control parameters, and the output levels of renewable generators. This complexity presents a significant challenge in studying the intricate control interaction phenomena and deriving appropriate countermeasures.

The book is beneficial for industry professionals, engineers, and academic researchers working on power systems in general, and specifically on power electronic converters.
