摘　　要：随着我国电动汽车产业的不断发展,关于电动汽车接入电网的研究日益增多,但多数只考虑了单一目标,如经济效益最优或环保效益最优。提出电动汽车接入下的电网多目标交易;考虑电动汽车的V2G特性,得到其充电功率;从单目标研究入手,分别建立以排量和价格为单目标的函数,得到最优解。进一步构建多目标函数,将购电费用和排放量转化为隶属度函数(单目标),最终得到兼顾双方、经济效益和环保效益折中后的最优解,对大规模电动汽车接入后电网的运行调度起到一定的辅助决策作用。The electric vehicle industry develops rapidly in China in recent years.However,the current grid trade research,using single objective model as the main research instrument,could not equilibrate the collective effect to the grid when various factors are taken into consideration,such as power purchase price,emissions,etc.Based on this situation,we propose the multiobjective optimization transaction research of the grid under the EV access.Firstly,the EV charging power result is obtained considering its V2G characteristic.Starting with the single objective model,the optimum solutions for the single objective evaluation of electricity costs and charging emissions are acquired separately.Then,the multi-objective optimization is carried out,which can take both the electricity cost and charging emissions optimizations into considered.The proposed evaluation method would make positive contribution to the power grid dispatching.
