Monitoring, Analysis and Mitigation of Oscillations in Power Systems
December 3, 2021 @ 2:30 pm - 3:30 pm
Poorly damped or undamped oscillations present a significant threat to the secure and economic operation of power grids. The number of oscillation events and their severity have been increasing, due to stressed and atypical grid operating conditions and changing resource mix with the increasing integration of renewables and retirement of conventional generators. In conventional power grids, power system stabilizers (PSS) on conventional generators have been used to suppress oscillations. However, the retirement of conventional plants is expected to result in insufficient stabilizing capability from the remaining generators, the location of which may also render them inappropriate to suppress these oscillations. Phasor Measurement Units (PMUs) and Synchrophasors is an emerging technology for grid monitoring and control. With PMUs due to the high resolution and GPS synchronized measurements oscillations can be monitored. This presentation will summarize recent EPRI’s work on the topic of oscillations mitigation and control. Co-sponsored by: University of Nevada, Reno Speaker(s): Rr.
