To improve the operating flexibility of coal fired units is an effective and necessary way for our country and even the world to solve the problem of large-scale renewable energy integration in grid. Five key strategies including the condensate throttling, cold source throttling, extraction steam adjustment of heating units, optimal load dispatch in power plants, and wide-range load operation of circulating fluidized bed (CFB) units, were given and introduced exquisitely. The static and dynamic models for the condensate throttling and cold source throttling were set up, which had enough accuracy to be directly used for the design of control system and strategy. The combination coordinated control with condensate throttling or cold source throttling was designed, which can greatly reduce the stepping out time from the load change dead zone, and accelerate the load change speed.
