Integration of a grid-connected solar photovoltaic system for electric vehicle charging stations: design and simulation analysis
摘要
Recently, the growth of Renewable Energy Sources (RES) together with the growing use of sustainable technologies like Electric Vehicles (EVs) has increased awareness concerning climate change mitigation. This study aims to design and evaluate an Electric Vehicle Charging Station (EVCS) powered by grid-connected photovoltaic energy that combines environmental and economic benefits. The main aims are to evaluate a proposed PV power plant, analyze its energy yield and power losses, and evaluate its techno-economic feasibility in the context of sustainable transportation. The research methodology is based on simulation and modeling using PVsyst software. The analysis includes PV module selection, tilt angle optimization, assessment of system losses and performance ratio, and the generation of power and temperature distribution curves. The proposed system, covering 6000 m2, is further assessed in terms of annual energy output, payback period, and greenhouse gas (GHG) emission reductions. The results show that the system is capable of providing an annual energy yield that is high enough to guarantee a stable EV charging, and a reduction of 33, 294.8 tCO₂ over its lifetime. The investment is also economically feasible, with a payback of 2.9 years and acceptable operating and maintenance costs. Overall, this insight from the results can help inform engineers, system developers, and policymakers, highlighting the potential of grid-connected solar-powered EVCS as a promising way to build sustainable energy and transportation systems.
