Control Strategies of Reversible Chargers for Electric Vehicle Charging Storage and Discharging Station
To fully use the bidirectional energy flow characteristics of the electric vehicle (EV) charging-storage- discharging station and the connected distribution network, modeling and control strategies of a key reversible is presented. A reversible charger mainly includes a PWM rectifier and a bidirectional DC/DC converter, on the one hand, based on the fed forward decoupling control, the double closed loop method of voltage and current is used for the reversible PWM rectifier. On the other hand, to extend the EV battery lifetime, in the bidirectional DC/DC converter, a two-stage control strategy with a first current closed loop and a secondly voltage closed loop is used for its charging, and discharge current closed loop control is also presented. By the simulation of the charge and discharge control for the reversible charger, results have shown that the presented control strategies can achieve the low harmonic performance of the bi-direction energy flow, and has a good robustness of load disturbance and high charge and discharge rates for EV battery.
