“双碳”目标下基于合作博弈的“源-荷”低碳经济调度

The"source-load"low-carbon economic dispatch based on cooperative game under the"double carbon"goal

面对当前电力系统低碳性与经济性难以同时兼顾的问题,考虑“源-荷”双方协调合作,将“荷”侧可供调度的灵活响应资源引入到系统中共同参与低碳经济调度。文章构建“源-荷”合作低碳经济系统并阐述其交互机理;以合作联盟总成本最小为目标,建立基于合作博弈理论的“源-荷”合作低碳经济调度模型,并且采用Shapley值法对合作收益进行分配;通过算例,对比源荷合作与不合作两种情况下,以及“荷”侧不同可转移负荷比例下系统总运行成本及碳排放量,验证了“源-荷”合作对兼顾系统低碳性与经济性的可行性及有效性。结果表明,“源-荷”双方协调合作对提升系统低碳经济性有积极作用。

In the face of the problem that it is difficult to give consideration to both low-carbon and economy of the current power system,the coordination and cooperation between"source and load"should be considered.The flexible response resources available for scheduling on the"load"side are introduced into the system to jointly participate in low-carbon economic scheduling.Firstly,it constructs the“source-load”cooperative low-carbon economy system and expounds its interaction mechanism.Then,aiming at minimizing the total cost of cooperative alliance,a"source load"cooperative low-carbon economic scheduling model based on cooperative game theory is established,and the Shapley value method is used to distribute the cooperation income.Finally,an example is given to compare the total operation cost and carbon emission of the system under the two cases of"source-load"cooperation and non-cooperation,as well as different transferable load ratios on the"load"side.The feasibility and effectiveness of"source-load"cooperation in taking into account the low-carbon and economy of the system are verified.The results show that the coordination and cooperation between"source-load"has a positive effect on improving the low-carbon economy of the system.
