Abstract: This paper handles the virtual implementation of the Unified Power Quality Controller (UPQC) in distribution network to improve the excellence of power in an electrical distribution network. The UPQC mainly consists of a series and a shunt active filter. The harmonics compensation is achieved series filter by providing a sinusoidal network current. Whereas, the distortion in the network such as sag, swell and flicker are balanced by the shunt active filter by providing the voltage. The Proposed system uses phase lock loop (PLL) control algorithm for series filter and hysteresis current controller (HCC) for shunt filter. The results of the proposed system are appraised by comparing with Dynamic Voltage Restorer (DVR) scheme of control. The proposed control scheme of UPQC proved that quality of power can be significantly better than DVR Scheme of control.
