摘要
随着我国碳中和及碳达峰的目标逐步推进,新能源发电量占我国能源总体比例不断提升,作为火电主力的燃煤机组在我国能源结构中的地位由主要电力来源转变为调峰电源。因此,燃煤机组开展灵活性改造成为行业趋势。就目前机组灵活性改造的主流技术路线进行对比研究,分别就火电机组+储能系统的技术路线及机组低负荷稳定运行下技术改造的适用范围及优缺点进行介绍,最后提出了在灵活性改造中应需遵循的原则。
With the gradual advancement of carbon neutrality and carbon peaking in China,the proportion of new energy power generation in Chinese total energy continues to increase.As the main coal-fired power generation unit,its position in China's energy structure has changed from primary power source to peak-shaving power source.Therefore,flexible transformation of coal-fired units has become an industry trend.It conducts a comparative study on the mainstream technical routes of the current unit flexibility transformation.The technical route of thermal power unit plus energy storage system and the equipment transformation under low load and stable operation of the unit are introduced respectively.The scope of application,advantages and disadvantages are introduced.Finally,the principles that should be followed in the flexibility transformation are put forward.
