摘　　要：电、热系统协调运行能够提高电力系统的灵活性,缓解我国“三北”地区供暖期间的弃风问题。提出一种综合能源系统低碳经济调度模型,并建立极限消纳风电的储热放热速率与电锅炉电功率的综合协调模型。针对电、热系统信息的隐私性问题,采用Benders分解算法对模型进行求解。算例仿真分析5种情景下系统储热和电锅炉对风电消纳的促进作用,比较电锅炉加装在热网始端、中间及末端对热网热损失的影响,最后,通过对比不同储热放热速率与电锅炉电功率协调供热的系统弃风情况,验证所提极限消纳风电的储热与电锅炉综合协调模型的正确性。The integration of electricity and heating systems has great potential to enhance the flexibility of power system to accommodate more wind power during the heating period in ＂Three North＂ region of China. This paper proposed a low-carbon economic dispatch optimization model. The minimum coordinated heating relationship of the ultimate wind power accommodated the heat release rate of thermal storage and the electric power of electric boiler was presented. Considering of the information privacy of electricity system and heating system, Benders decomposition algorithm was proposed to solve this model. The results show the wind power accommodation in five scenarios, the low-carbon economic performance and the best node to join with the heating networks by considering of the energy transmission loss. Finally, the effectiveness of the coordinated heating relationship of the thermal storage and the electric boiler was verified.
