Abstract :
This paper presents a systematic approach to predict the structural characteristics of power systems following large disturbances. Specifically, this paper uses the normal form of vector fields to predict the onset of the interarea separation in power systems following large disturbances. The normal form method is well established in the dynamical systems theory literature. The paper develops an analytically based index which identifies the onset of the interarea separation. The proposed approach has been applied to the 50-generator IEEE test system. The results obtained indicate that the proposed index effectively captures the structural characteristics of the system dynamic behavior and accurately predicts the nature of the system dynamic performance following large disturbances
