摘　　要：针对传统的实体储能设备因建设成本较高而难以大规模应用的问题,提出了考虑电-热等效虚拟储能的综合能源系统低碳经济调度模型。首先,通过采用住宅用户热舒适度这一指标调节热负荷并与热电联产(combined heat and power, CHP)机组相结合,形成热力等效虚拟储能。其次,将碳捕集设备视为可调节负荷并与需求侧响应一起作为电力等效虚拟储能参与削峰填谷。此外,在负荷低谷时碳捕集设备以最大功率运行可以有效降低CHP机组的CO_(2)排放量。最后,以购能成本、弃风成本、CO_(2)封存成本、碳交易成本、需求响应补偿成本之和最小为目标建立模型。算例仿真结果表明同时考虑热力等效虚拟储能、需求响应与碳捕集设备协同作用,提高了综合能源系统整体的风能渗透率与经济性,同时降低了CO_(2)的排放量。As broad application of traditional physical energy storage equipment is difficult due to high construction costs,the low-carbon economic dispatch model of an integrated energy system considering electric-thermal equivalent virtual energy storage is proposed in this paper.First,the heat load is adjusted using the thermal comfort index of residential users and combined with combined heat and power(CHP)units to form a thermally equivalent virtual energy storage.Second,the carbon capture equipment is regarded as an adjustable load,and participates in peak shaving and valley filling as an equivalent virtual energy storage with a demand-side response.In addition,the carbon capture equipment operates at the maximum power during periods of low load,which can effectively reduce the CO2 emissions of the CHP units.Finally,a model is established with the goal of minimizing the sum of energy purchase costs,wind curtailment costs,CO2 sequestration costs,carbon transaction costs,and demand response compensation costs.The simulation results of the example show that,considering the synergy of thermal equivalent virtual energy storage,demand response,and carbon capture equipment simultaneously;the overall wind energy penetration rate of the system is improved,carbon emissions are reduced,and the economy of integrated energy system is improved.
