Abstract

Poor voltage regulation is experienced for the costumers connected at the end of low voltage distribution grid. In the proposed paper, voltage regulation is achieved in the distribution grid using Unified Power Quality Compensator (UPQC). Different control techniques are used for shunt inverter in UPQC to improve the power quality of the Distribution Grid. Control techniques, including the PI control, DQ control and Minimum Power Point Tracking (mPPT) for voltage control are analyzed and simulated in the proposed paper. Simulation with UPQC is done for three different control techniques and its performances are compared. The mPPT avoids the circulation of unnecessary reactive compensation for voltage regulation by operating at the Minimum Power Point (mPP). Comparative analysis is made for UPQC with the different control techniques during sag, swell and fault condition. The simulation of distribution Grid for voltage regulation using UPQC is carried out using MATLAB Simulink.
