摘　　要：当前综合能源系统经济调度研究的重点是兼顾系统的经济效益与环境效益。在此基础上,考虑负荷侧影响,引入综合需求响应,建立以降低系统运行成本和减少碳排放为目标的低碳经济调度模型。首先,根据负荷响应特性建立了综合需求响应模型;其次,利用机会约束描述风电出力不确定性并运用通用分布处理;再次将模型线性化处理后,运用NSGA-Ⅱ算法求解模型中的多目标函数;最后,选取IEEE33节点与比利时天然气20节点系统展开分析。实验结果表明:所构建的低碳经济调度模型可以有效提升系统运行经济性,同时兼顾环境效益。The key issue of the current economic dispatch of the integrated energy system is to balance economic and environmental benefits. On the basis of current research, considering the impact of the load side, the integrated demand response is introduced to establish a low-carbon economic dispatch model with the goal of reducing system operating costs and carbon emissions. Firstly, according to the load response characteristics, an integrated demand response model is established;secondly, the uncertainty of wind power output is described by chance constraints and processed by versatile probability distribution;Thirdly, the model is linearized and NSGA-II algorithm is used to solve the multi-objective function;Finally, the IEEE 33 node and the Belgian natural gas 20 node system are selected for analysis. The simulation results show that the low-carbon economic dispatch model constructed in the article can effectively improve the economics of system operation while taking into account environmental goals.
