Abstract

This paper presents, a multistage LQR is introduced and applied for simultaneous coordinated designing of the unified power flow controller (UPFC ) and power system stabilizer (PSS) as a damping controller in the single machine power system. The results of these studies show that the proposed coordinated controllers have an outstanding capability in damping power system inter-area oscillations and enhance greatly the dynamic stability of the power system. The dynamic stability characteristics are investigated with PSS and UPFC acting individually and as a hybrid system. The hybrid controller shows a better performance compared to individual controllers. The proposed technique is implemented using MATLAB/SIMULINK platform.
