新型电力系统下火电机组灵活性运行技术发展及挑战
Development and Challenge of Flexible Operation Technology of Thermal Power Units Under New Power System
摘要
Abstract
Under the background of"dual carbon",new energy has begun to be connected to the grid on a large scale.Still,the randomness and volatility of new energy generation have a specific impact on the power grid,and it is urgent to build a new power system.The need for flexibility is further deepened in the process of building new power systems.In this process,as the cornerstone of the power system,the traditional thermal power will transform to the basic security and system regulatory power supply that provides reliable capacity,peak regulation and frequency modulation and other auxiliary services,and the flexible transformation of thermal power units has become an inevitable choice.The phased objectives,difficulties and challenges of building a new power system were analyzed,and the problems encountered in the flexible transformation of thermal power units at the present stage were discussed.Combined with thermal power operation data,the technical ways of configuring energy storage equipment for thermal power units were analyzed.The research shows that there are some problems in the process of building a new power system,such as the power system stability,difficulties in the transformation of traditional thermal power,energy consumption,environmental protection and so on.The flexibility transformation of thermal power units is faced with some problems,such as the insufficient peak regulation capacity,high operation cost,load response,operation energy consumption and safety,etc.The operation mode of thermal power plus energy storage will bring better economic and environmental benefits.关键词
