UPFC control parameter identification for effective power oscillation damping

摘要

This paper presents UPFC control parameter identification for effective power oscillation damping (POD). A comparative analysis with minimum singular value (MSV), Hankel singular value (HSV), direct component of torque (DCT) and residue has been proposed for finding the most appropriate control input parameters of unified power flow controller (UPFC) for damping power system oscillations. The basic objective of the paper is to identify the control parameters of UPFC in order to provide adequate damping in power network with changing system conditions. The results presented in this paper are studied widely on single machine infinite bus. The test has also been carried for two area systems and same trend has been observed. The results show the suitability of this approach in identification of UPFC control parameters.
