Oscillations in power systems have always been a significant concern, and the increasing integration of inverter-based resources (IBRs) has introduced new complexities. These oscillations can result in equipment disconnections, supply interruptions, equipment damage, and violations of reliability criteria.
To support practitioners in diagnosing and mitigating these issues, the Energy Systems Integration Group (ESIG) Stability Task Force has developed a practical guide, Diagnosis and Mitigation of Observed Oscillations in IBR-Dominant Power Systems. Designed as both a field guide and a diagnostician’s assistant, this resource helps identify root causes, suggests solutions, and provides access to further materials. The guide begins with foundational information for those new to the topic and progressively delves into more detailed content.
In March 2024, ESIG, in collaboration with the Global Power System Transformation Consortium (G-PST), also hosted a special workshop on oscillations. Experts worldwide shared their experiences, best practices, and latest research. Engaging with ESIG and G-PST offers valuable opportunities to stay at the forefront of understanding and resolving oscillation issues. Researchers and professionals focused on risk management will find ESIG’s technical working groups, including the Stability Task Force of the Reliability Working Group, particularly beneficial.
