Today’s LiveWire Spotlight looks at a newly released NERC Technical Reference detailing various methods to detect and mitigate wide-area oscillations.  The document explains how to (1) conduct analyses that determine the shape, frequency, and damping coefficients of natural and forced oscillations, (2) use the analysis results to identify the parameters to monitor, the placement of sensors, and the alert thresholds to set, and (3) determine actions that prevent oscillations at the local and system level before they can occur or should they manifest themselves unexpectedly.
NERC has seen a correlation in the number of oscillation events to the penetration rate of high-speed BES Facility controllers.  This Technical Reference can help TOPs and RCs who are interested in identifying where their vulnerable points are before an issue arises.
