Abstract

Photovoltaic panel arrays (PV) to be integrated into electric vehicle charging stations (EVCS) for clean transportation goals can increase hybrid power system (HPS) potentials, especially in countries with lower energy purchase prices. In this study, the optimum HPSs with minimum cost considering PV capacity and solar radiation for morning, midday and night peak demand profiles are comprehensively analyzed from technical, economic and environmental perspectives. Moreover, possible PV capacity and solar radiation threshold points are determined depending on the power quality issues at critical bus nodes by considering self-consumption. The results show that increases in solar radiation and PV capacity can reduce the payback period by up to 2.73 years and increase HPS opportunities by up to 31.1%. Power quality issues cannot be eliminated due to lower SCR for PV capacity of 800 kW and above and solar radiation of 5.5 kWh/m2/day and above, except for midday peaks.
