Design and Optimization of an Electric Vehicle Charging Station Supported Hybrid Energy System in Bursa Orhaneli

Abstract

In this study, a grid-connected hybrid energy system consisting of photovoltaic (PV) panels, wind turbines, battery energy storage, and the utility grid was designed to supply the energy demand of an electric vehicle charging station planned in the Kadi District of Orhaneli, Bursa. The system design and optimization were carried out using the HOMER Pro Microgrid Analysis Tool.

Different PV capacities, numbers of wind turbines, battery storage capacities, and converter ratings were defined for a residential load with a total daily electricity consumption of 450 kWh/day, along with an additional electric vehicle charging load of 60 kWh/day, and the system was optimized based on the minimum net present cost (NPC) criterion.

The results indicate that grid-supported hybrid energy systems provide lower levelized cost of energy (LCOE) and higher operational reliability compared to fully renewable off-grid configurations. Therefore, the proposed system presents a technically and economically feasible solution for electric vehicle charging infrastructure in rural areas.
