Aiming at the problem of optimal distribution of dust removal, desulfurization and denitrification load in thermal power plants, considering the cost of environmental protection, from the perspective of improving the comprehensive economic benefits of the whole plant, the relationship between coal consumption and power generation of the unit is described by using quadratic polynomial. Based on this model, it can be obtained. The unit corresponds to the fuel cost of different power. Considering the cost of environmental protection, the cubic polynomial is used to model the relationship between the pollutant concentration of the unit and the power generation of the unit. The total cost of peak shaving of the unit is calculated by the unit price of pollutant emissions in different periods. In addition, considering the efficiency of desulfurization and denitrification when the unit is operated under low load conditions, the concentration of pollutants in the exhaust gas is increased, which causes additional environmental costs of government fines, and a model of additional cost is proposed. Based on the actual operating data of the unit, a model for optimal comprehensive economic benefit was established and the constraints were established. And verify the correctness of the model.
