A comparative analysis of D-FACTS devices for power quality improvement in photovoltaic/wind/battery system
Year: 2025
Type: article
Abstract: The identification and reduction of power quality events have become essential because of the growing interest in incorporating renewable energy sources to power system. The primary aim of this paper is to compare the performances of dynamic voltage restorer (DVR), unified power flow controller (UPFC) and unified power quality conditioner (UPQC) to improve power quality issues in grid-connected photovoltaic/wind/battery system by mitigating total harmonic distortion (THD). The results of the proposed research have been validated using MATLAB platform. The comparative analysis of DVR, UPFC, and UPQC in mitigating THD in a grid-connected PV/wind/battery system is presented in this paper. The comparative analysis of the results depicts that THD in voltage decreases from 51% to 44.67%, 20.94%, and 16% whereas THD in current decreases from 58% to 44%, 29.26%, and 22% after implementation of DVR, UPFC, and UPQC respectively in the proposed photovoltaic/wind/battery system. The effectiveness of the proposed system has been confirmed by comparing the results with already published techniques.
