Modelling of Hybrid Microgrid with EV Charging Station Using HOMER Pro

Urban energy systems are increasingly challenged by the growing integration of renewable energy and the rising demand for electric vehicle (EV) charging infrastructure. This study presents the design and optimisation of a hybrid microgrid system integrating photovoltaic (PV) systems, battery energy storage systems (BESS), and EV charging stations for urban environments. The system configuration is optimised using HOMER Pro software to minimise Net Present Cost (NPC) while maximising renewable energy utilisation under varying EV charging load conditions. Real-world data, including solar irradiance profiles and time-of-use (TOU) electricity pricing are integrated to ensure practical applicability. Key findings indicate that the system effectively adapts to increasing EV charging de-mands by scaling PV capacity, BESS throughput, and grid power usage. Sensitivity analyses highlight the significant impact of load variability and electricity pricing on economic performance, demonstrating the robustness of the proposed microgrid design across diverse scenarios. This work underscores the potential of hybrid microgrids to mitigate the challenges associated with large-scale EV adoption, reduce reliance on grid power, and contribute to decarbonisation efforts. The findings provide a valuable reference for developing cost-effective and sustainable energy solutions in urban settings.
