The increase in greenhouse gas due to fossil fuel-powered generators, industries, and automobiles has led to severe climate change over the past decade. This led to an increase in renewable energy sources for power generation and Electric Vehicles (EVs) in the automobile industry. This work focuses on the effective utilization of renewable energy sources consisting of wind energy and solar PV systems for electric vehicle battery charging by interfacing through dc bus. The proposed dc bus voltage controller maintains a constant voltage at the dc bus under various environmental conditions like wind gusts, zero solar irradiation, and grid interruption. The design and stability aspects of the dc bus voltage controller are analyzed in detail using frequency domain analysis. The robustness of the proposed controller is tested with recorded field data of wind velocity and solar irradiation. The feasibility and efficacy of the proposed controller design are confirmed for the EV battery charging station using real-time simulation studies. The results are compared with the IEEE 519 standard, verifying the efficacy of the proposed controller design.
