Advanced DVR and Strategic BESS Arrangement for Superior Voltage Sag Mitigation in Distribution Networks

Abstract

Increased integration of short circuit faults created disturbances in the distribution system with the number of voltage generation profiles in the system, making voltage regulation a tedious task. However, the DVR brings an opportunity to solve these issues, as they can provide renewable local energy and also act as voltage regulation components in the network. In this paper, an optimized DVR and an optimally placed BESS framework are used to overcome voltage-sag and voltage-swell problems S-OOA optimizes DVR, through ideal parameter tuning of PID controllers, this improved the steady state response of DVR. BESS is optimally located using HGJHA by analyzing the most frequent voltage dips. By integrating this DVR and the BESS the voltage support capabilities were increased, and power quality and voltage stability were also increased. By implementing and evaluating the proposed model in MATLAB/Simulink, it shows better power quality of up to 95%. which outperforms previous approaches.
