Abstract
Forced oscillations have the potential to impact reliable and secure power systems operations. The Western Interconnection (WI) is observing an increase in forced oscillation events, both local and system-wide, with an increase of inverter-based renewable energy sources. This paper discusses SCADA and synchrophasor measurement-based operating procedures and tools implemented in the control center to monitor and mitigate forced oscillations. An example of a recent wide-area forced oscillation event is included that shows how the RC operators used these measurement-based tools and operating procedures to locate the source and mitigate the forced oscillations in the WI maintaining reliable and secure system operations. An offline analysis of the event is also included in this paper.
