Design and development of the platform for electric vehicle to grid

In order to facilitate the long-term and flexible experimental study of the mutual influence between the electric vehicle V2G technology and the power grid, this paper designs and develops a large capacity experimental platform for EV to grid. The paper presents the basic design idea of the V2G experimental platform. The AC/DC unit adopts the improved feed-forward compensation control strategy to improve the anti disturbance capability of DC bus, while the DC/DC units relize the charging and discharging function with the current closed-loop control. An experiment is carried out to verify the basic function of the platform, which shows that the the platform can be applied to study the interaction between the EV charging load and the power grid.
