Grid Integration of PV Based Electric Vehicle Charging Stations: A Brief Review

Solar photovoltaics (PVs) and electric vehicles (EVs) can play a critical role in bringing down global carbon emissions and promoting green energy. Charging of EVs is dictated by their dependency on the grid. The inclusion and integration of PVs in the EV charging schemes will minimize their grid dependency and add flexibility to the system. Further, EVs can function as storage for both the grid and the PV systems to reduce the uncertainty in PVs' intermittency. Due to their complementary nature, PV-based EV charging stations have been discussed rigorously in the literature. This paper briefly reviews the contemporary literature on the modeling of grid-connected PV-based EV systems. The paper compiles the assessment of various modeling components and their parameters for optimal charging scenarios to aid readers in realizing modeling complexities and opportunities. In the end, the review concludes with a synopsis of future research directions for PV-based charging systems.
