Locate the Source of Resonance-Involved Forced Oscillation in Power Systems Based on Mode Shape Analysis

Abstract

This paper proposed a new method to locate the source of forced oscillation that involves resonance with natural oscillation modes. The new method is based on comparing the oscillation mode shape of the forced oscillation with that of the natural oscillation that the forced oscillation resonates with. The oscillation source is the location that has the largest angle difference between the forced oscillation mode and the natural oscillation mode. Some examples in the actual U.S. EI system verified this approach.
