Currently

a lot of distributed generators and household electric vehicles are connected to the grid. The increase in capacity and the variety of loads have made it impossible to support the new load demand by the original microgrid. It is imperative to establish a new microgrid system that can meet a variety of needs. Taking into account the comprehensive constraints and the orderly charging

this paper develops a multi-objective optimal planning model in AC/DC hybrid microgrid system with wind turbine generators

photovoltaic generation

energy storage battery and electric vehicle. In order to reduce the cost of configuration and the load fluctuation

CPLEX optimal programming has been used to solve the objective function. The case study compares the difference between the new AC/DC hybrid microgrid and the original microgrid. A study is made on the rationality of electric vehicle orderly charging as well as the influences of interaction between the two types of microcrids on optimized configuration. The results verify the effectiveness and feasibility of the approach proposed.
