摘　　要：现有电–气互联综合能源系统规划研究中少见有负荷波动考虑,究其原因是量测数据不足,造成信息条件边界不明确,规划模型适用性低。基于此,提出一种基于信息间隙决策理论(information gap decision theory,IGDT)的电–气互联综合能源系统多目标扩展规划模型。首先,在搭建多目标扩展规划模型基础上,对电、气负荷各自最大波动范围的不确定集合进行描述;其次,采用IGDT对典型场景下不确定因素水平进行量化,并通过电力传输线重构扩大规划模型优化边际;最后,采用改进型ε–约束算法对多目标混合扩展模型进行求解,并利用模糊决策确定所得pareto解集下的最优规划方案。IEEE-RTS 24节点与比利时20节点系统仿真结果表明,所提模型能有效量化综合能源系统负荷多重耦合不确定因素影响,利用电力传输线重构能有效提升规划方案优化空间。Load fluctuation is rarely considered in the planning of integrated natural gas and electric power systems.The reason is that the boundary of information condition is not clear and the applicability of planning model is low for lack of measurement data.Based on this,a multi-objective expansion planning model for transmission level integrated energy system based on information gap decision theory(IGDT)is proposed.Firstly,based on the multi-objective expansion planning model,the uncertainty sets of the maximum fluctuation range of electric and natural gas loads are described.Secondly,the information gap decision theory is used to quantify the level of uncertain factors in typical scenarios,and the optimization margin of the planning model is expanded through transmission switching.Finally,the improved epsilon-constrained algorithm is adopted to solve the multi-objective expansion planning model,and the optimal planning scheme under the pareto solution set is determined by fuzzy decision-making.The simulation results of IEEE-RTS 24 node system and Belgium 20 node system show that the proposed model can effectively quantify the impact of multiple coupling uncertainties in the integrated energy system load,and transmission switching can effectively enhance the planning optimization space.
