Guidelines for Subsynchronous Oscillation Studies in Power Electronics Dominated Power Systems

Subsynchronous oscillations (SSO) have been identified as a major concern in modern power systems. Especially, the introduction of power electronic devices such as HVDC, FACTs and renewable generation has escalated SSO related issues. Considering the need of the industry, this technical brochure has been developed to provide a general guideline for understanding the relevant SSO phenomenon, study methodology, mitigation/prevention techniques and protection mechanisms.
