Abstract

Interarea power oscillation damping enhancement in large inter-connected power systems is often accomplished using supplemen-tary controls at the synchronous machines involved and with the use of flexible ac transmission system (FACTS) devices. The power system literature has demonstrated that wide area signals could be more effective than the local signals for these controllers. In some cases in which phasor measurement units (PMUs) are used, the required control signals may not be available. To allevi-ate these cases, control signals are obtained using estimated sig-nals from a "dynamic state estimator", and a robust supplemen-tary controller is deployed. In this paper the cited strategy is illustrated using a static var compensator. The feasibility of the proposed method has been demonstrated on the IEEE 50-generator test system.
