Stability Analysis of Grid-Connected Converters

Provides a deep understanding of the mechanisms, analysis methods, stability criteria, and stabilization methods for converter-driven oscillations in power systems The extensive integration of converter-interfaced resources into power systems has significantly increased the occurrences of converter-driven oscillations, posing a serious new challenge to power system stability over the past decade. Stability Analysis of Grid-Connected Converters offers a comprehensive understanding of converter interactions with power systems and their oscillation characteristics. Based on academic research, this book is to explicitly connect mathematical mechanism and converter-driven oscillation phenomena, helping readers with deep insight into converter-driven oscillations. To provide a solid foundation for studying converter-driven oscillations, the book is organized into ten chapters, covering topics such as stability mechanisms, modeling, stability criteria, analysis methods, and stabilization techniques for different types of converters. Equipping readers with the knowledge to design stable converter systems and tackle critical power system challenges, Stability Analysis of Grid-Connected Converters: Describes the history of converter-driven oscillations and presents recent understandings and categorizations of these oscillations in sub-synchronous oscillation classification and power system stability classificationPresents modeling methods for typical converter control approaches, including grid-following and grid-forming convertersExplains the mechanism of mirror-frequency oscillations induced by converters and clarifies the fundamental causes of converter-driven oscillationsProvides comprehensive stability analysis methods and distinctions in their applications, including the impedance measurement methods for stability analysis for black-box systemsAnalyzes and specifies the stability characteristics of both grid-following and grid-forming converters, with relevant stabilization measures provided accordingly Stability Analysis of Grid-Connected Converters is an essential resource for engineers, system operators, and converter designers addressing power system stability challenges. It is also an excellent supplementary text for graduate and advanced undergraduate courses in power systems, renewable energy integration, and power electronics.
