Hybrid Renewable Energy System for Efficient Electric Vehicle Battery Charging Using Solar PV and Wind Integration

Abstract

The integration of renewable energy sources for electric vehicle (EV) battery charging has gained significant attention due to the increasing need for sustainable transportation solutions. This study presents the design and simulation of a hybrid energy system, combining rooftop solar photovoltaic (PV) and wind energy for efficient EV battery charging. The solar energy system is connected through a boost converter, with a duty cycle controller ensuring maximum power point tracking (MPPT) to optimize the energy harvested from the PV array. Simultaneously, the wind energy system is connected via a permanent magnet synchronous generator (PMSG) coupled to a wind turbine. The output from the PMSG is rectified using a three-phase diode bridge rectifier (DBR) and is also linked to a boost converter, controlled by a duty cycle controller, to stabilize the voltage and optimize the charging process. Both energy sources are integrated to charge the EV battery, ensuring a reliable and continuous energy supply. The boost converters in both subsystems are essential for managing voltage fluctuations and improving the charging efficiency of the EV battery. The system's performance is evaluated in MATLAB/Simulink, focusing on the control strategy of the duty cycle controllers and the interaction between the solar and wind subsystems. The results demonstrate the feasibility and effectiveness of the proposed hybrid system in delivering a stable and efficient EV battery charging solution, emphasizing the role of renewable energy in achieving sustainable electric mobility.
