Model-Enhanced Localization of Forced Oscillation Using PMU Data

Abstract:

The detection and mitigation of low-frequency forced oscillations are important for reliable grid operation. Forced oscillations, driven by periodic disturbances such as malfunctioning controllers [1], may resonate with poorly-damped natural modes across wide areas of the grid, and risk large system failures. Locating the source within the system is a prerequisite for mitigation schemes to correct the actions responsible for the original oscillation. We introduce a model-enhanced method for locating the source of a forced oscillation using PMU measurements. This method augments the use of data-only approaches, such as the energy based function inspired dissipating energy flow method. The algorithms are tested on several scenarios using a 240-bus, 178-line WECC model.
