Abstract：In the context of building a new type of power system,coal power units are accelerating their transformation towards being cleaner,more efficient,and flexible through flexibility retrofitting,heat supply retrofitting,and energy-saving and carbon reduction retrofitting.With the large-scale development of variable renewable energy and the continuous rise in energy demand,coal power continues to play a crucial role in ensuring the security of energy supply in China for a considerable period of time,fulfilling three roles:power supply,heat supply,and providing grid flexibility.This transformation brings numerous challenges to coal power.This paper,based on the new circumstances facing China's power transition,identifies the contradictions and challenges faced by coal power units in flexible peak regulation and stable heat supply.It analyzes the technical measures related to thermoelectric decoupling and draws from both domestic and international experience.The research suggests that through enhanced support for flexibility retrofitting,strengthening heat supply retrofitting and system optimization,further improvement of power market design,and intensified efforts in thermoelectric decoupling technology research,coal power can achieve flexible peak regulation and stable heat supply at the same time,contributing to the enhancement of China's energy security and promoting the integration of renewable energy.
