Development of New Predictors Based on the Concept of Center of Power for Transient and Dynamic Instability Detection

This paper proposes a novel approach based on the center of power (COP) applied on a sliding window for real-time instability prediction. Synchrophasor measurements are obtained from phasor measurements units connected at strategic locations of the network. In order to assess the instability, the new concept of COP from which two new indices are derived is defined. These new indices are used as predictors in a detection algorithm based on random forest of decision trees. Three study cases carried out on the IEEE 4 generators 10 buses, the Australian 14 generators, and the New England test system allowed validating successfully the performance of the proposed method.
