Study on Unit Optimal Scheduling Considering the joint constraint of “deep peak load regulation and coal consumption”

The peak load regulation ability of thermal power unit is closely related to the deep peak load regulation mode of thermal power unit and the peak load regulation strategy of power system. Meanwhile, the deep peak-load regulation ability is affected by many factors. In order to meet the increasing demand for peak load regulation, it is necessary to study the economy of deep peak load regulation of thermal power units under the condition of large-scale wind power grid connection from the perspective of thermal power enterprises, wind power enterprises and society. In this paper, taking full account of the current deep peak load regulation capacity and coal consumption cost control strategy of thermal power units, considering the economy of the deep peak load regulation stage of thermal power units, a unit combination optimization model with the joint constraint of "deep peak load regulation and coal consumption" is established, and the coordinated operation scheme of each thermal power unit after the wind power unit is connected to the system is arranged as a whole.
