Efficient power management for sustainable EV charging station in DC microgrids

Abstract

As the world shifts to sustainable transportation with electric vehicles, it's essential to boost power generation to meet the growing demand. Renewable energy emerges as a superior alternative to conventional power sources for electric vehicle charging. The study explores the operational reliability and efficiency of renewable energy-powered EV charging in various modes, including direct charging from solar PV, battery-assisted charging, and hybrid modes combining both sources. The multimode operation of the proposed system has been simulated in the MATLAB/Simulink platform. It has been observed that integrating solar PV and battery energy storage for EV charging offers a flexible and robust solution in remote areas and results in reduced grid dependency. This proposed system gives important insights into the design and implementation of sustainable electric vehicle charging systems, supporting the progress of green transportation technologies.
