Power Quality Enhancement in Solar–wind Hybrid Ev Charging Stations Integrated With Three-phase Grid
Year: 2025
Type: article
Abstract: The integration of renewable energy sources, such as solar and wind power, into Electric Vehicle (EV) charging stations presents a promising solution for sustainable transportation. However, ensuring high power quality in these systems is essential for the efficient operation of both the charging stations and the grid. This project compares the power quality improvement in solar and wind-based EV charging stations interconnected with a three-phase grid. Power quality parameters such as voltage stability, harmonics, power factor, and frequency regulation are evaluated for both systems. Solar-based systems, benefiting from predictable energy generation during daylight, generally exhibit superior performance in terms of voltage stability, harmonic reduction, and power factor correction, with the ability to integrate seamlessly with energy storage solutions. In contrast, wind-based systems offer the advantage of continuous power generation in regions with consistent wind, but they face challenges due to variability in wind conditions and more complex control mechanisms. Both systems contribute to frequency regulation and voltage support, albeit with different levels of consistency. The project concludes that while both solar and wind- based EV charging stations can significantly improve power quality, the optimal solution depends on local environmental factors, grid infrastructure, and the need for energy storage integration
