Abstract
Power flow is one of the major problems in a transmission system. When a fault occurs in a transmission system there is said to be a drop in the voltage. Voltage sag is one of the most severe problems to be dealt with as it causes severe process disruptions and results in substantial economic loss. Decrease/increase of reactive power is also one of the main problem. FACTS devices are used to control the power flow to increase the transmission capacity and to optimize the stability of the power system. One of the most widely used FACTS devices is Unified Power Flow Controller (UPFC). Here, the sending end voltage is generated by the wind generation system. In this study, researchers are comparing two different controller’s performance. The two controllers are PI and Fuzzy. On comparing, researchers can say that Fuzzy Logic Controller (FLC) based UPFC shown better voltage sag compensation than PI controller based UPFC. Matlab/Simulink is used to create the PI and FLC and to simulate UPFC Model.
