Optimized Power Quality Enhancement Using UPQC in EV-Integrated Distribution Networks

Abstract

 The research examines the complete simulation framework for an electric vehicle charging system which merges an AC-DC converter with a DC-DC converter next to advanced control circuits. Power conversion management functions with stable and reliable charging operations as part of this system design. The grid delivers its AC power through filtering before rectification which allows a DC-DC converter to adjust and meet the requirements of an EV battery. Results obtained using MATLAB/Simulink demonstrate that the system performs admirably under a range of grid conditions and operating loads. Three key performance criteria are assessed by the system: total harmonic distortion (THD), voltage regulation, and power factor correction. According to the testing findings, this system is a next-generation DC fast charging solution since it reduces harmonic signals, improves system stability, and offers great power efficiency. The control strategies that have been put in place enable adaptive power supply, extend battery life, and increase system reliability. The findings of this study show how EV infrastructure's optimized power electronics promote the growth of environmentally friendly transportation.
