Abstract
The growing popularity of electric vehicles (EVs) has resulted in the creation of several renewable-powered grid-connected charging stations. Therefore, choosing a suitable control mechanism for these charging stations is critical to optimizing their efficiency and minimizing their influence on the grid. This study compiles a novel power plant controller (PPC) strategy for renewable-powered grid-connected EV charging stations (EVCS). It illustrates the comparative analysis by implementing Q droop controllers and constant V controllers. This paper explores grid-scale, multi-tasking, PPC-based renewable-powered EVCSs, employing various control techniques to optimize performance and grid integration. The study demonstrates enhanced efficiency, stability, and reliability in managing renewable energy and EV charging demands. The research looks at how various control strategies perform regarding charging efficiency, power quality, and grid stability. The simulation findings reveal that each control strategy has advantages and limits, and the best decision is determined by the charging stations and the grid’s individual requirements. The findings of this study offer useful insights into the selection of appropriate control techniques for renewable-powered grid-connected EVCSs in order to ensure efficient, dependable, and sustainable charging. This paper presents a comparative analysis of different control techniques used in renewable-powered grid-connected EVCSs to identify the most suitable control technique for the efficient and reliable operation of multi-load-facilitated grid EVCS.
