摘　　要：针对热电联产机组在冬季供暖期间的“热电冲突”和弃风消纳问题,文中提出了计及碳交易成本和价格型需求响应的热电联合低碳经济调度模型,同时引入了电锅炉和储热装置解耦热电耦合限制,研究了不同运行方式对优化调度的影响。在系统中考虑碳交易成本,限制碳排放,并通过用户侧需求响应来增强电网调峰能力,对负荷曲线进行优化,有效削减了负荷的峰谷差,为风电上网提供了空间。最后,采用CPLEX求解器进行求解,并基于改进的IEEE-30节点系统进行仿真分析。结果表明,在文中调度方法下风电消纳量提高了83.72%,碳排放量减少了2211 t,验证了该调度模型的可靠性。In view of the problems of thermoelectric conflict and abandoned wind power during winter heating,a low-carbon economic dispatch model for combined heat and power that takes into account carbon trading costs and price-based demand response is proposed,while electric boilers and heat storage devices are introduced to decouple the coupling limits of thermoelectricity to study the impact of different operation modes on optimal dispatch.Carbon trading costs are considered in the system to limit carbon emissions,and the user-side demand response is used to enhance the peak regulation capability of the grid and optimize the load curve,effectively cutting the peak-to-valley difference in load and providing space for wind power to go online.Finally,the CPLEX solver is used for solving and simulation analysis is carried out based on the improved IEEE-30 node system.The results show that the wind power consumption is increased by 83.72%and carbon emissions are reduced by 2211 t under the scheduling method proposed in this study,which verifies the reliability of the scheduling model.
