Optimal Feed-back Switching Control for the UPFC Based Damping Controllers

چکیده

-This paper presents an optimal feed-back switching concept for the Unified Power Flow Controller (UPFC) based damping controllers for damping low frequency oscillations in a power system. Detailed investigations have been carried out considering switching between two optimal damping controllers; one with respect to modulating index of shunt inverter and another with respect to modulating index of series inverter . The proposed UPFC switching model presented here is tested on the modified SMIB linearised Phillips-Heffron model of a power system installed with UPFC using MATLAB/SIMULINK® platform. The investigations reveal that the proposed optimal feed-back switching control between UPFC damping controllers and provides moderately better performance with respect to settling time for both individual controllers as well as coordinated damping controller.
