An approach for optimal power oscillation damping with UPFC

This paper presents an optimal power oscillation damping (optimal POD) controller design with unified power flow controller (UPFC). A systematic analysis of optimal POD controller has been presented with state space model developed in a generalized framework for single machine infinite bus (SMIB) and two area system. The approach is modular and general enough so as to include any sub system. The controller designed shows excellent performance for variety of loading conditions. The sample system has been studied and the results presented are in good agreements to the existing operational domain of the UPFC.
