摘　　要：文章提出了考虑分布式可再生能源交易的风电运营商与电动汽车充电站的协同优化调度模型。不同于传统的协同运行方式,文章以市场化交易的手段激励风电商与充电站的协同优化运行。同时,建立了基于合作博弈的能源交易模型;并且不同于传统纳什议价利益分配方法,文章根据交易过程中交易主体对整体社会福利提升的贡献水平,构建了更公平合理的考虑议价贡献度的收益分配方式。为了保护隐私,提出了基于一致性算法的分布式方法求解协同优化调度模型;并且通过KKT(Karush-Kuhn-Tucker)条件给出了基于议价贡献度的收益分配解析解。仿真结果表明,该协调机制能促进风电商与充电站的可再生能源交易,有效提高风电商的盈利水平并降低充电站的用电成本,从而实现收益的公平分配。This paper proposes an optimal collaborative scheduling model for wind power operators and electric vehicle charging stations(EVCSs)considering the distributed renewable energy trading.Different from the traditional collaborative operation method,this paper motivates the collaborative operation of the wind power operators and the EVCSs in the market-based approaches.At the same time,an energy trading model based on the cooperative game is established,and a benefit distribution method considering the bargaining contributions is constructed according to the contribution levels of the participants to the overall social welfare enhancement during the trading process,which overcomes the deficiency of the traditional Nash game benefit distribution ignoring the contributions.In terms of the privacy protection,a distributed approach based on the consistency algorithm is proposed to solve the collaborative optimal scheduling model;and the analytical solution of the benefit distribution based on the bargaining contributions is given under the KKT(Karush-Kuhn-Tucker)condition.The simulation results show that the coordination mechanism is able to promote renewable energy trading between the wind power operators and the EVCSs,which effectively improves the profitability of the wind power operators,reduce the operating cost of the EVCSs,and achieve a fair distribution of the revenue.
