摘　　要：针对目前我国可再生能源占比逐步增加,而整体利用效率不高的问题,提出了将电动汽车作为主动负荷,消纳微网中可再生能源的经济调度模型,利用遗传优化算法求解经济调度模型。研究表明电动汽车的接入以及可再生能源的使用不但可以节约微电网的投产资金与运行维护费用、减少环境污染,还能够充分发挥电动汽车作为主动负荷起到削峰填谷的作用,提高了微网的经济性。Aiming at the problem that the proportion of renewable energy sources in China is increasing gradually,but the overall utilization efficiency is not high,this paper proposed the economic dispatch model to take the electric vehicle as the active load to consume and absorb the renewable energy sources and the genetic algorithm was used to solve the economic dispatch model.The research result shows that the access of electric vehicles and the usage of renewable energy sources not only save the production and operating maintenance cost of microgrid and reduce the environmental pollution,but also give full play to the peak clipping and valley filling functions for the electric vehicles as active load,which improves the economy of microgrid.
