The rapid growth of Electric Vehicle (EV) charging stations has raised concerns about their impact on grid stability. This paper presents a study on integrating PV Systems with smart inverters in EV charging stations to enhance grid stability and energy efficiency. Two scenarios are analyzed: one without smart inverters and one with their integration. In the absence of smart inverters, charging events are poorly aligned with energy supply, resulting in voltage fluctuations, grid instability, and higher operational costs. However, the introduction of smart inverters significantly improves the situation. It optimizes charging operations, reduces energy waste, enhances grid stability, and minimizes voltage fluctuations. The proposed system's model and mechanism are comprehensively analyzed using the ETAP platform. This research underscores the vital role of smart inverters in promoting eco-friendly charging and improving overall grid stability in the context of EV charging stations.
