摘　　要：随着我国“双碳”目标的不断推进,新能源的发展日益增强,为构建新型电力体系,火电在未来相当长的时间内扮演着调峰电源的角色。分析了常规火电机组和储能系统耦合火电机组灵活性改造技术路线的适用性,分析得出在不改造原有主机设备条件下增加储热系统可以大幅度提升机组的调节灵活性。对于机组供暖期的灵活性调节方面,可增加电锅炉+储热水罐形式;对于纯凝期机组灵活性调节方面,可以增加熔盐储热系统。通过总结储热系统提升火电机组调峰能力的特点和发展趋势,为火电灵活性改造采用何种技术路线提供参考。With the continuous promotion of China's“double carbon”goal,the development of new energy is increasing,in order to build a new type of power system,thermal power in the future for a long time to play the role of the peak power supply.This paper analyses the applicability of the flexibility transformation technology route of conventional thermal power units and thermal power units coupled with energy storage systems,and concludes that the flexibility of unit regulation can be greatly improved by adding heat storage systems without transforming the original host equipment.For the flexibility regulation of heating period,electric boiler+hot water storage tank can be added;for the flexibility regulation of pure condensing period,molten salt heat storage system can be added.By summarising the characteristics and development trend of thermal storage system to enhance the peak shifting capability of thermal power units,the article provides a reference for what technical route to be adopted for thermal power flexibility transformation.
