EV Residential Charging Station With Renewable Energy Sources

Abstract

The rapid growth of electric vehicles (EVs) has created an urgent need for reliable and sustainable charging infrastructure, as conventional grid-powered stations contribute to greenhouse gas emissions and increase grid dependency. This study investigates the design and performance of a residential EV charging station in Hai-Alandalus, Libya, powered by renewable energy sources. Using HOMER Pro software, three microgrid configurations were simulated: a grid-connected PV–wind hybrid, an autonomous microgrid with PV and one wind turbine, and an autonomous microgrid with PV and two wind turbines. The analysis incorporated local solar and wind resources, household demand, EV charging patterns, and battery storage performance. The results show that the grid-connected system is the most cost-effective, with a renewable fraction of 78.9% and the ability to export surplus electricity, although it remains partially reliant on the grid. In contrast, the autonomous systems achieved renewable fractions up to 89.3% and eliminated operational emissions but required higher capital investments and exhibited significant levels of excess electricity. Overall, the findings confirm that renewable-powered EV charging stations are technically feasible and environmentally beneficial in regions with high solar–wind potential. While grid-connected hybrids provide the most economical pathway, autonomous systems deliver full decarbonization. Future research should focus on smart charging strategies, vehicle-to-grid integration, and optimization methods to enhance efficiency and economic viability.
