Progress of flexible operational control technology for coal-fired units

Speeding up the construction of a new power system is the key to promoting the realization of the "dual carbon" target. The connection of a large proportion of intermittent wind and solar renewable energy has brought new challenges to the safe and stable operation of the power system, and has also put forward higher requirements for the fast, deep and flexible operation capabilities of coal-fired units. In this paper, the modeling methodology and flexible operational control technology for coal-fired units were described and analyzed based on the the development history of intelligent and flexible peak-shaving control technology. The analysis results show that the hybrid modeling method supplemented by machine learning and other intelligent system identification methods, as well as the integration of predictive control, adaptive control, multi-objective intelligent optimization, etc. are more suitable for the needs of flexible and intelligent control of future coal-fired units, and are the main direction for the development of flexible and intelligent control technology for coal-fired units.
