HYBRID ENERGY SYSTEM FOR EV CHARGING STATION USING PV FED Z-SOURCE MODIFIED LUO CONVERTER AND FUEL CELL INTEGRATION
Abstract
Electric vehicle (EV) adoption is rising rapidly, necessitating the development of efficient and sustainable EV charging stations. Conventional EV charging stations depend heavily on grid power, leading to energy security concerns, high costs, and limited renewable energy utilization. This paper proposes a hybrid energy system integrating photovoltaic (PV) technology and fuel cells through a centralized DC bus. A Z-source modified Luo converter is used in the PV system, regulated by a Walrus-optimized PI controller to ensure stable voltage output. A boost converter with a PI controller enhances the fuel cell's output voltage. The energy sources are connected to a three-phase voltage source inverter (VSI) to deliver consistent power to the EV charging stations. The proposed system optimizes energy utilization, improves efficiency, and reduces dependency on fossil fuels, making it a viable solution for future EV infrastructure.
