A Novel Control Scheme for TransZSI-DVR to Enhance Power Quality in Solar Integrated Networks

Abstract

This paper aims to study and evaluate the performance of a novel control scheme for Dynamic Voltage Restores (DVR) with Transformer-based Impedance Sourse Inverter (Trans-ZSI) configuration. An Improved Maximum Constant Boost Control (IMCBC) method is proposed to enhance the overall performance of solar PV fed TransZSI-DVRs. The proposed technique contributes to THD reduction and voltage stress mitigation across the switches. A model developed in Matlab/SIMULINK is tested under different types of voltage disturbance. The results show the effectiveness of the proposed control method as a corrective approach in compensating the voltage at the point of common coupling.
