摘　　要：核供热具有清洁低碳、高效可靠等优点,特别是一体化小型堆供热-发电综合能源系统具有热电逆向耦合特性,合理利用这一特性有助于提高系统经济性,促进风电消纳。考虑需求响应是实现综合能源系统经济高效运行的重要途径。基于SMR控制回路阐述其运行过程中存在的热电逆向耦合特性,根据电力负荷价格弹性响应模型推导建立需求响应模型。以系统运行成本最小为目标,建立SMR热电综合能源系统日前优化调度模型,实现能源供给侧和需求侧的协调优化。最后划分不同供能场景进行仿真,计算结果表明,需求响应模型可以准确描述电价对多能用户的影响,为系统运营商提供更为合理的调度方案,考虑需求响应的SMR热电综合能源系统日前调度模型在提高系统的经济效益和综合能效方面优势显著。Nuclear heating has the advantages of clean,low carbon,high efficiency and reliability,and especially the all-in-one small modular reactor(SMR)heating and power generation integrated energy system has thermoelectric reverse coupling characteristics.Rational use of this characteristic will help improve system economy and promote wind power consumption.Considering demand response is an important way to achieve cost-effective operation of an integrated energy system.Based on the SMR control loop,the thermoelectric reverse coupling characteristics in the operation process were described,and the demand response model was established according to the power load price elastic response model.With the goal of minimizing the operating cost of the system,a day-ahead optimal scheduling model of SMR thermoelectric integrated energy system was established to realize the coordination and optimization of energy supply side and demand side.Finally,different energy supply scenarios were divided for simulation.The calculation results show that the demand response model can accurately describe the impact of electricity prices on multi-energy users,and provide a more reasonable scheduling scheme for system operators.The day-ahead scheduling model of the SMR thermoelectric integrated energy system considering demand response has significant advantages in improving the economic benefits and comprehensive energy efficiency of the system.
