摘　　要：电动汽车达到一定规模后可能带来大量充电负荷,为使收益最大,提出充换电站应采用充电与换电相结合的工作方式,充電模式采用直接从电厂购电,而换电模式通过电网购电。以充换电站的运营收益最大为目标,结合了合同电价与市场电价之间的联动模型对该工作模式下的充换电站运营进行了经济效益分析,确定了最佳充换电比例。最后针对某地区充换电站运营进行了算例分析,证明了此方法的可行性。Because certain-scale electrical vehicles（EVs）will bring the heavy charging load,the operating mode combined with charging and exchanging power is proposed to get the best profit in this paper.And power is purchased directly from power plant in charging mode,while it is purchased from power grid in exchanging mode.The maximum income of charging and exchanging power station is taken as the objective function,and the optimized proportion of charging and exchanging power is determined by considering of economic benefit of charging and exchanging power station operation under running mode that is analyzed by using of linkage model between contract price and market price.In the end,the example analysis is carried out on the operation of certain charging and exchanging power stations,which verifies the feasibility of proposed method.
