Abstract Plug-in electric vehicles (PEVs) integration will pose inevitable impacts on the planning and operation of microgrid system in the future. The microgrid economic dispatch model (MEDM) considering electric vehicles integration is presented and the impact of different charging and discharging modes on microgrid economic operation is analyzed. The charge and discharge power of the PEVs and the output of the distributed generation units were scheduled and the objective function is to minimize a combination of the operation cost as well as the power purchase costs of PEV users. An improved genetic algorithm optimization module was proposed to achieve the optimization. Application of the proposed energy management model on a small microgrid system shows the validity of the method and the computation results can be used to evaluate the impact of PEV charge and discharge modes on economical performance of microgrids.

Key words： keywords：Plug-in electric vehicle (PEV) microgrid economic dispatch orderly charge and discharge optimization algorithm
