Revenue optimization method and device for cogeneration unit

Abstract

The invention is suitable for the technical field of electric energy, and provides a revenue optimization method and device for a cogeneration unit. The method comprises: obtaining parameter data which at least comprises frequency modulation auxiliary service data, power generation data, heat supply data, fuel application data and unit maintenance application data; obtaining a revenue function of the cogeneration unit according to the parameter data; and optimizing the revenue function to obtain target data of the cogeneration unit. The revenue function of the cogeneration unit is established according to the acquired parameter data, and the influence of the frequency modulation auxiliary service data, the power generation data, the heat supply data, the fuel application data book and the unit maintenance application data on the revenue of the cogeneration unit is fully considered, so that the revenue of the cogeneration unit can be optimized, the earnings of the cogeneration unit can be improved and adjusted, and the supply-demand relation with customers is adjusted accordingly.

Description

technical field [0001] The invention belongs to the technical field of electric energy, and in particular relates to a method and device for optimizing the revenue of a cogeneration unit. Background technique [0002] Since electric power cannot be stored on a large scale at present, the real-time balance between power generation and power consumption must be realized in the power system, otherwise it will cause fluctuations in the frequency of the power grid, so frequency modulation auxiliary services are produced. Here it mainly means that the generating set adjusts its output through Automatic Generation Control (AGC) and Automatic Corresponding Area Control Deviation (ACE), so as to balance with the power consumption, so as to realize the adjustment of the frequency of the power system. The effect of tuning is measured in FM mileage. With the continuous deepening of my country's power system reform, the scope and scale of power market transactions have grown rapidly. F...
