Optimal Allocation of Microgrid with Integration of Electric Vehicles Charging Load

电动汽车行业的快速发展使得电动汽车充电负荷对电网的影响日益凸显。文章围绕包含风电、光伏、储能电池和电动汽车的微电网的优化配置问题,建立了综合约束条件下含电动汽车有序充电的微电网多目标规划模型:以降低优化配置成本为目标,应用CPLEX优化软件求解。算例比较了电动汽车无序充电和有序充电模式下对微电网优化配置的差异,验证了所提方法的合理性和有效性。

The rapid development of electric vehicle industry makes the impact of electric vehicle charging load on the grid increasingly prominent.Taking into account of comprehensive constraints and the orderly charging,this paper develops a multiobjective optimal planning model in microgrid system with wind turbine generator,photovoltaic generation,energy storage battery and electric vehicle.In order to reduce the cost of configuration and the load fluctuation,CPLEX optimal programming had been used to solve the objective function.The case study compares the difference between autonomous charging mode and coordinated charging model.The results verify the effectiveness and feasibility of the approach proposed.
