Research on Photovoltaic-Energy Storage-Charging Smart Charging Station and Its Control optimization

With its characteristics of distributed energy storage, the interaction technology between electric vehicles and the grid has become the focus of current research on the construction of smart grids. As the support for the interaction between the two, electric vehicle charging stations have been paid more and more attention. With the connection of a large number of electric vehicles, it is bound to bring a load impact that cannot be ignored on the grid. To this end, this article proposes a multi-energy complementary smart charging station that adapts to the future power grid. It combines photovoltaic, energy storage and charging stations, and uses energy storage systems to cut peaks and fill valleys to effectively balance the load fluctuations of charging stations. It also provides a charging station control strategy and energy optimization model based on photovoltaic-energy storage-charging and other energy clusters, which reduces the load fluctuation of the charging station while reducing its operating costs.
