摘　　要：配电业务有序放开的市场环境下,分布式发电(DG)运营主体的市场行为将进一步增加其出力的不可控性。配电网运营主体需要通过采用电价等手段对DG的出力进行一定程度上的干预和调度控制,以降低分布式电源接入带来的不确定性。为此,提出了一种以市场合作博弈理念为基础、考虑配电网气体减排任务分配的配电网络节点电价定价方法。根据气体减排和配电网运营主体收益的优先级,将其最佳策略应用于节点电价的计算,以对参与节能减排的分布式电源机组进行价格补偿。算例结果表明:此方法能够基于DG的减排任务完成情况对配电网络节点电价进行确定,且在激励DG参与节能减排方面要优于传统方法。随着未来节能减排约束的趋紧,所提出的方法对于节点电价的制定及配电系统的高效、安全运营具有较高的参考价值和良好的现实意义。Under distribution businesses orderly opening,the market behavior of Distributed Generation(DG)operators further increase the uncontrollability of their output.Distribution network operators need to use electricity pricing and other means to implement a certain degree of intervention and scheduling control on DG output to reduce the uncontrollability caused by the access of distributed power.This paper proposes a Locational Marginal Price(LMP)pricing method in distribution networks based on gas emission reduction allocation of DG using market cooperative game theory.Based on the priority of gas emission reduction and distribution network operators'benefit,the proposed pricing policy requires decision maker to simply apply its best response strategy to the LMP calculating,so as to carry out price compensation for the DG units participating in energy saving and emission reduction.The example result shows that the method can determine the price of DG nodes based on the completion schedule of emission reduction task.And the performance of this method is superior to the traditional method in the aspect of promoting energy conservation and emission reduction.With the tightening of energy conservation and emission reduction constraints in the future,the proposed method has high reference value and practical significance for the formulation of LMP and the efficient and safe operation of distribution system.
