Abstract: With the development of electric vehicle（EV），there are a large number of EV charging load in the

power grid. Because of its unique advantages，AC/DC microgrid is more convenient for the access of AC slow

charging pile and DC fast charging pile. However，large-scale EVs integration will bring impact to the power grid

and endanger the safe operation of the power grid. Aiming at the optimal dispatching problem of AC/DC microgrid

with EVs，taking into account the mobile energy storage characteristics of EV，the charging mode of users was

determined according to the emergency degree of charging，the model was established with the minimum goal of

user side cost，network loss cost，abandoned wind and light cost and load fluctuation cost. Based on the methods of second order cone relaxation，absolute linearization and linearization of product variables，the solution was

presented. Finally，the results show that the dispatching strategy is effective and can satisfy the good access of EVs

toAC/DC microgrid.
