Operation scheduling optimization method and system of power system, medium and terminal

The invention discloses an operation scheduling optimization method and system of a power system, a medium and a terminal, and the method comprises the steps: traversing each scene, solving a new energy scene security constraint unit combination model based on the predicted output value of each new energy unit in the power system in the current traversal scene and the related data of the power system, the method comprises the steps of obtaining a current first unit combination sequence, updating the start-stop state of each unit to be dispatched in the current first unit combination sequence according to a solving result, and then inputting the current first unit combination sequence into a security constraint economic dispatching model for solving after traversing all scenes, so as to obtain the output power of each unit to be dispatched. And scheduling optimization is carried out on the power system according to the first unit combination sequence and the output power of each to-be-scheduled unit. According
