Integration of Electric Vehicle (EV) chargers with grid-connected hybrid renewable energy systems to bolster grid stability and sustainability is an essential step in the domain of new energy solutions. In the context of climate change and the global transition to new energy paradigms, the current study emphasizes the role of EV chargers, powered by autonomous photovoltaic (PV) sources, in mitigating voltage sags during grid faults. Through the use of Vehicle to Grid (V2G) technology and a fuzzy-controlled bidirectional converter, the system ensures efficient battery management and rapid response to energy demands. The study findings highlight the significance of EV chargers as potential auxiliary power sources, contributing to sustainable energy solutions, reducing the carbon footprint, and enhancing the resilience of our energy infrastructure in the face of climate challenge.
