Solar-powered EV charging stations offer a sustainable and reliable alternative to traditional infrastructure, significantly alleviating stress on legacy grid systems. However, the intermittent nature of renewable energy sources poses challenge for management in power distribution networks. To address this, optimal charge/discharge scheduling EVs becomes crucial. This paper introduces an innovative Opposition-based Competitive Swarm Optimization (OCSO) technique minimize total cost IEEE 33-bus system. Five strategically placed solar-powered distinct buses are evaluated under three modes: dumb charging, smart grid-to-vehicle (G2V) vehicle-to-grid (V2G) charging. Comprehensive analyses performed critical parameters, including bus voltage stability, load profiles, electricity state-of-charge (SOC) dynamics, thermal performance transformers. Notably, losses reduced by 13.7% 21.6% G2V V2G modes, respectively, compared Furthermore, cumulative ageing factor transformers is 11.86%, indicating extended transformer lifespan. These findings demonstrate that stations, coupled with advanced strategies, can effectively mitigate impacts, enhance operational efficiency, contribute reducing net carbon emissions.
