The main focus of the paper is to compensate the Reactive Power generated in the isolated wind–diesel hybrid system and enhancement of the Voltage stability by the use of Fuzzy PI based UPFC Controller. Linearised small signal model of the wind-Diesel System with different loading conditions is taken with IEEE Excitation system. In this paper the compensation has been carried out with UPFC Controller for different loading conditions. A self tunned Fuzzy PI controller is designed to tune the parameters of PI Controller Kp and Ki. Simulation result shows that the parameters of the system attend steady state value with less time due to the proposed controller.
