Title

Power Quality Improvement of AC Distribution System using PV- UPQC with Modified p-q Theory Based Control

Abstract

This paper proposes a modified p-q theory based control of solar photovoltaic (PV) array integrated unified power quality conditioner (PV-UPQC-S). The system incorporates clean energy generation along with power quality improvement thus increasing functionality of the system. The fundamental frequency positive sequence (FFPS) components of voltages at the point of common coupling (PCC) are extracted using generalized cascaded delay signal cancellation (GCDSC) techniques which are then used in p-q theory based control to estimate reference signals for the PV-UPQC-S. This modification in p-q theory enables its application for PV-UPQC-S control in conditions of distorted PCC voltages. The series voltage source converter (VSC) of PVUPQC- S operates such that it shares a part of the reactive power of the load even under nominal grid conditions. This increases the utilization of the series VSC while reducing the rating of shunt VSC. The PV array is integrated at the DC-bus of the UPQC, provides a part of active load power thus reducing demand on the supply system. The dynamic performance of modified p-q theory based PV-UPQC-S is verified by simulating the system in Matlab/Simulink with combination of linear and nonlinear loads. The steady state and dynamic performances of the system validated through extensive testing on a scaled down laboratory prototype.
