Design of power oscillation damping controller for SVC device

SVC devices are used to improve voltage and reactive power conditions in AC systems. An additional task of SVC is to increase transmission capacity as result of power oscillation damping. A residue-based method for analysis and control of power system oscillations has been explained. In this paper the design of power system damping controllers using residue method is addressed. Eigenvalue analysis and time domain simulations were performed on a 11-bus two-area system and the results demonstrated the effectiveness of the proposed controller.
