Unit commitment accelerated optimization method, system and device based on constraint enhancement and medium

The invention discloses a unit commitment accelerated optimization method, system and device based on constraint enhancement and a medium, and relates to the technical field of unit commitment, and the method comprises the steps: building a unit commitment model based on the system cost, system constraint and decision variables of the unit commitment; the unit output upper limit constraint and the climbing constraint of any two adjacent time periods are reinforced, and a reinforced constraint inequality is obtained; and then adding the reinforced constraint inequality into the solving process of the original unit commitment model to realize accelerated optimization of the unit commitment. According to the method, the unit output upper limit constraint and the climbing constraint are enhanced, so that the unit commitment model is enhanced, the branching frequency is reduced, the unit commitment solving speed is increased, and the method has guiding significance in engineering practice. 本发明公开了一种基于约束加强的机组组合加速寻优方
