Under the current situation that the growth of the power demand is slowing down and renewable energy is developing rapidly

the flexibility reform of thermal power units becomes an effective way to reform the current power supply-side. Referring to the characteristics of China energy structure and the deep peak load regulation status at home and abroad

the feasibility and necessity of flexibility reform of China's thermal power units are discussed in this study. According to the actual transformation results of a subcritical 330 MW heating unit flexibility reform demonstration project

the goal of flexibility transformation and effective technical means to improve the unit's deep peak load regulation capacity are analyzed. And it is also demonstrated that the early implementation of the flexibility reform is the necessary choice for thermal power units to respond to the peak load regulation policy of power grid

enhance market competitiveness

and improve the lifecycle of the enterprise. The flexibility reform should follow the "one plant

one program" policy

not only according to the characteristics of enterprises

reasonable transformation targets and technical solutions

but also taking into account that the future changes in the market

investment scale

and the actual demand.
