Gas power plant optimization control method and system

The embodiment of the invention provides a gas power plant optimization control method and system, and belongs to the technical field of gas power plants. The method comprises the steps that real-time operation parameters of a target gas power plant are collected, and a unit heat balance calculation model is built based on the real-time operation parameters; correcting the heat balance calculation model based on a pre-constructed combustion auxiliary component doping scheme contrast library to obtain a combustion auxiliary component doping scheme; the combustion auxiliary component doping scheme is executed, and unit operation information in the execution process is monitored; and correcting the combustion auxiliary component doping scheme in real time based on the unit operation information until the combustion auxiliary component doping is completed. According to the scheme, the energy consumption of the unit under all working conditions is reduced, and the operation economy of the unit is improved. 本发明实施例提
