Instability Detection Technologies in Power Electronics Systems

This technical report discusses instability detection technologies in power electronic-dominated systems, emphasizing their importance for maintaining a reliable electricity supply in a decarbonized European economy. The report outlines the challenges posed by the integration of power electronics interfaced devices (PEIDs) and the phasing out of synchronous machines, which necessitate advanced instability detection methods. It evaluates various technologies that can effectively identify instability, including measurement-based modal analysis and Wide Area Monitoring Systems (WAMS). The report also highlights the limitations of current measurement technologies and the need for improved data handling and standardization among European Transmission System Operators (TSOs). Additionally, it provides recommendations for addressing the growing instability challenges, such as the development of real-time analysis algorithms and enhanced time synchronization techniques. By focusing on these aspects, the report aims to contribute to the creation of a more resilient power system capable of supporting the increasing reliance on renewable energy sources.
