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.
