中文摘要:

      发展综合能源系统是实现经济发展和节能减排的关键举措。首先，为提高机组的调峰能力、减少CO2的排放，将碳捕集技术引入综合能源系统，研究其对综合能源系统灵活、经济、低碳运行的作用。然后，为减轻负荷和风电峰谷波动给系统带来的压力，考虑电、热负荷的需求响应作用，实现综合能源系统的健康、可持续运行。最后，考虑能源协调与耦合作用，以最小化综合成本为目标，构建电-热综合能源系统低碳经济调度模型。算例分析的结果表明，碳捕集和需求响应的共同作用减少了系统的总运行成本和碳排放成本，从源荷双侧促进了风电的消纳，促进了电-热综合能源系统的灵活调度和低碳运行。

英文摘要:

      The development of an integrated energy system is a key initiative to economic development, energy conservation and emission reduction. Firstly, to improve the peaking capacity of the units and reduce CO2 emissions, carbon capture technology is introduced into the integrated energy system, and its role in the flexibility, economic, and low-carbon operation of the integrated energy system is studied.Then, to reduce the pressure on the system caused by fluctuations in load and wind power peaks and valleys, the role of demand response of electric and thermal loads is considered to achieve healthy and sustainable operation of the integrated energy system. Finally, the role of energy coordination and coupling is considered, and a low-carbon economic dispatch model for the integrated electricity-thermal energy system is constructed to minimize the comprehensive cost. The results of the analysis show that the combined effect of carbon capture and demand response reduces the total operating cost and carbon emission cost of the system, promotes the consumption of wind power from both the source and load sides, and facilitates the flexible dispatch and low carbon operation of the integrated electricity-thermal energy system.
