Summary
The power systems are becoming dominated by power electronics. This introduces new technical challenges in terms of oscillatory instabilities and converter interactions. The CIGRE C4.49 Working Group (Multi-frequency stability of converter-based modern power systems) has examined new forms of instabilities and interactions driven by power electronic converters in modern power systems. The Technical Brochure presents an overview, status and outline of oscillatory instabilities and interaction analysis in converter-based systems. It covers definitions, classification, literature review and industry experience including state-of-the-art stability and interaction analysis in power systems dominated by converters. Moreover, it elaborates about small-signal instability phenomena, consolidate definitions, and explain available methods for analyses with their advantages and disadvantages to provide a common understanding within the academia and industry. General guidelines for the studies considering available information at different stages of an asset lifetime as well as choice of tools and mitigation methods are also touched upon within the Technical Brochure. The theoretical part is aided by benchmark system examples.
