摘　　要：高比例可再生能源增加了电力系统的负荷波动性和不确定性,需要热电联产系统具备更强的灵活性,熔盐储热设备的应用能够提升热电联产系统的此性能。针对某耦合熔盐储热设备的“4炉2机”母管制热电联产系统,基于EBSILON仿真软件建立供电、供热的机理模型,分析熔盐储热设备对热电联产系统性能的影响,研究耦合系统的优化调度方式。研究结果表明:热电联产系统耦合熔盐储热设备可以增加系统调峰容量,扩大系统运行范围,拓宽机组运行区域;经过估算,一天内煤量可节省约4.16 t,碳排放量下降约8.25 t,污染物排放量下降约1.76 kg,熔盐储热设备提高了系统的经济性和环保性。The growing share of renewable energy leads to increased load volatility and uncertainty in power system,necessitating greater flexibility in cogeneration systems.The utilization of molten salt thermal storage equipment can enhance the performance of cogeneration systems.Against the main-pipeline cogeneration system consisting of four boilers and two steam turbines which is integrated with a coupled molten salt thermal storage equipment,the EBSILON simulation software is used to establish mechanism model for power supply and heating.The influence of molten salt heat storage equipment on combined heat and power system performance is analyzed,and the optimization scheduling methods for coupled systems are also investigated.The results show that,the coupling of molten salt thermal storage equipment in cogeneration systems can increase the system’s peak shaving capacity,expand the system’s operating range,and broaden the unit’s operating area.After estimation,the amount of coal saved in one day can be about 4.16 tons,the carbon emissions can be reduced by about 8.25 tons,and the pollutant emissions can be decreased by about 1.76 kg.The molten salt thermal storage equipment has improved the system’s economy and environmental friendliness.
