Along with the rapid development of electric vehicles, the continuous construction and continuous popularization of electric vehicle power supply facilities has become an urgent need. Nevertheless, unlike traditional fuel vehicles, with the increase in the ownership of electric vehicles, the charging behavior of large-scale electric vehicles connected to the grid in the future will have a non-negligible impact on the grid. Disorderly charging of EVs will increase the peak load of electricity consumption across the grid and exacerbate the peak-to-valley difference in load. In particular, the popularity of fast charging will increase the complexity and uncertainty of EV loads while increasing the load on the grid. In order to suppress or eliminate the negative impacts of EV charging, distributed PV plants, EVs, energy storage devices and their control devices can be combined and operated together. In this study, a distributed photovoltaic charging station with an installed capacity of 94 kW is built based on the 2020 weather data of Lanzhou area. Throughout 2020, the distributed PV charging station for electric vehicles can provide 103,749.19 kWh of clean electricity for electric vehicles, equivalent to 41.5 tons of standard coal. Not only can it ease the pressure on the power grid, but it can also continue to provide real clean power for electric vehicles.
