【Title】Research and Simulation of V2G technology in micro grid
【Abstract】For the application of V2G technology in micro grid, the strategy of electric vehicle charging pile in micro grid is designed. When charging pile is discharged, the double closed loop control structure of voltage and current was applied by converter. The outside loop is voltage control and the inside loop is current control. Inverter is based on droop control and P/Q control which has the function of shifting peak and filling valley of active power. It can also be used as a dynamic reactive power compensation device to stabilize the voltage of the micro grid. When the charging pile is used for charging the electric vehicle, the inverter adopts the constant DC voltage reactive power control to stabilize the voltage of DC bus. At the same time Converter uses three kinds of control mode constants pressure, constant current and constant power , to meet the demand of electric vehicle charging. Finally simulation results verify the feasibility of the charging pile strategy.
