Hybrid Renewable Integration for Electric Vehicle Charging: A Path Toward Sustainable Mobility

The pursuit of decarbonized transportation has catalyzed the integration of electric vehicles (EVs) with renewables, including solar photovoltaics and hydrogen fuel cells, fostering a synergetic energy mobility ecosystem. Even though this convergence is quite promising, it introduces many meaningful challenges related to the intermittent nature of renewable energy sources (RESs) and the fluctuating high-power demands of EV charging. These dynamics may cause several power quality problems, including voltage instability, frequency variations, and harmonic distortions. The present chapter proposes an integrated hybrid renewable energy system that is suitable for EV applications. The proposed architecture adopts a hybrid energy management framework incorporating MPPT-based control and an active filter to accommodate high-power EV loads and effectively mitigates harmonic distortions, which are introduced by power electronic converters. Stand-alone and grid-integrated conditions are evaluated for the proposed multi-source system. The results, obtained through Fast Fourier Analysis (FFA), indicate that the total harmonic distortions (THD) are significantly reduced, and system efficiency and stability are improved, making it a viable and strong solution for the future of sustainable transportation.
