摘　　要：动态变化的电网对功率需求的紧急程度不同,不同紧急程度下车网互动所产生的收益也有所区别。为实现更加合理的互动收益分配,提出一种考虑电网场景区别的车网互动收益分配方法。通过场景系数反映电网功率需求紧急程度的不同,结合辅助服务等效替代分析车网互动的收益;考虑不同电价下电动汽车用户的响应概率,建立改进的讨价还价博弈模型以求解场景最优响应电价,从而得到互动双方的收益分配值。通过算例对比分析几种响应策略的负荷削减程度、收益及分配方式的公平熵值等评价因素,验证了该收益分配模型的有效性与优越性。As the urgency degree of the grid demand for power varies due to the dynamic change of the grid,the income generated by vehicle-to-grid(V2G)interaction also differs under different urgency degrees.To achieve a more reasonable distribution of the interaction income,this paper proposed a distribution method of the V2G interaction income that considers the difference in the power grid scenario.The scenario coefficient is used to reflect the urgency degree of the grid demand for power,and equivalent substitution of ancillary services is discussed to analyze the V2G interaction income.The response probability of electric vehicle users under different electricity prices is taken into account and an improved bargaining game model is built to solve the electricity price for the optimal scenario response and thereby obtain the income distribution shares of the two sides participating in the V2G interaction.The effectiveness and superiority of the proposed income distribution model are verified through the comparative case analysis of the load reduction degree,income,and fair entropy of the distribution method among several response strategies.
