On the impact of transportation electrification on distribution systems in the presence of rooftop solar photovoltaic

In this paper, the impact of plug-in electric vehicles charging on the electric power distribution system in the presence of single-phase rooftop solar photovoltaic (PV) is investigated. Monte Carlo methods are used to address the uncertainties resulting from solar irradiance and temperature in case of solar photovoltaic and PEVs charging demand. Twenty scenarios of different penetration levels of PVs and PEVs are studied in this work and simulated on the IEEE 123 bus radial power distribution system. The results of Monte Carlo simulations have shown that the increased use of PVs may significantly reduce the overload on distribution transformers resulting from PEVs charging, but it has no effect on the unbalance in distribution transformers resulting from PEV charging.
