Abstract: Electric vehicle (EV) charging stations have experienced rapid growth, whose impacts on the power grid have become non-negligible.

The charging station incorporates a battery energy storage and (i) limits the imported power based on grid-imposed requirements and (ii) its control system decouples dynamics of the station from those of the grid. The charging station can operate in either grid-connected mode or islanded mode.
One way to reduce the impact of fast charging on the grid is to encourage the use of renewable energy sources like solar PV along with the grid . Also, a bidirectional flow of energy can be established between the system and the charging station by using the concept of Vehicle-to-Grid (V2G) and Vehicle-to-Vehicle (V2V) charging.
The charging station can operate in either grid-connected mode or islanded mode. The dynamic models of the charging station, in both modes, are presented and eigenvalue analyses performed to design the Local Controllers (LCs).
Also, a bidirectional flow of energy can be established between the system and the charging station by using the concept of Vehicle-to-Grid (V2G) and Vehicle-to-Vehicle (V2V) charging. For that an optimal power flow strategy has to be implemented.
Moreover, a coupled PV-energy storage-charging station (PV-ES-CS) is a key development target for energy in the future that can effectively combine the advantages of photovoltaic, energy storage and electric vehicle charging piles, and make full use of them .
