Abstract

This paper presents a comprehensive approach for Coordinated Control (COC) of Series Vectorial Compensator (SVeC) and Power System Stabilizer (PSS) for damping Low Frequency Oscillations (LFO) in multimachine networks. SVeC is viewed as the most innovational series Flexible AC Transmission System (FACTS) device. Though PSS and SVeC devices have been incorporated separately in multi machine networks, optimal control strategy based on state feedback control for coordination of PSS and SVeC controllers under different loading conditions has not been developed. So, the Optimal State Feedback Controller (OSFC) for incorporating of PSS and SVeC controllers in COC manner has been developed in this paper. The performance of the aforesaid method is checked using eigen-value analysis and nonlinear time- domain simulation outcomes under numerous loading conditions together with nominal case. The comparison of performance of COC of SVeC and PSS in a Western System Coordinating Council (W.S.C.C) 3-machine, 9-bus system is investigated in this paper. The damping characteristics of the optimal controller for COC of SVeC and PSS are compared with COC, PSS and without control are analyzed. The outcomes of test system show that the proposed optimal control can improve the dynamic stability of test system significantly at different loading conditions.
