Considering thermal unit commitment mill Generation Scheduling Method

The present invention discloses a thermal unit commitment considering grinding power plan optimization methods, including (1) to obtain optimal scheduling for operational data model, maintaining thermal unit commitment grind Interval; (2) to obtain the latest physical models and real-time grid data mode, starts calculating sensitivity, the sensitivity obtained result information; optimization model basic data reading system (3) power generation plan, generation Unit Operation grind interval result information and sensitivity; (4) read according to step (3) all the input data, on the basis of optimal scheduling model, the introduction of thermal unit commitment constraints grinding, grinding of thermal unit commitment constraints modeling, optimization model considers the thermal unit commitment grinding form, the output information. Start and stop of the invention by introducing a mathematical model of grinding thermal power constraints, to avoid the continuous thermal power output fluctuations caused by frequent start and stop the mill, making the unit planning a more economical, more reliable, reducing the cost of electricity.
