Abstract—The proliferation of power electronic based equipment has produced a significant impact on the quality of electrical power supply. Unified Power Quality Conditioner (UPQC), which consists of double converters connected through a DC capacitor. With each other has high potential because of its high controllability. UPQC connected can insert a virtual inductance on the line and, at the same time, its shunt inverter can compensate the line voltage on SVG. The power quality variations are classified as either disturbance or steady state variation. In this paper Left Shunt Unified Power Quality Conditioner (L-UPQC) is proposed to improve the quality of the power delivered to the load. The role of UPQC is to convert the feeder (source) current to balanced sinusoids through the shunt compensation and converter load voltage (VL) to balanced sinusoids through the series compensator and also regulate it to a desired value. The performance of the left shunt (L-UPQC) is tested under different operating condition based on proposed controller to improve power quality of a single feeder distribution system. The simulation results and performance of both UPQC technologies is implemented on MATLAB/SIMULINK platform.
