Problems solved by technology

[0013] The preset optimization model is a compromise model that considers various operating states of the power grid. This model can satisfy various optimization objectives to a certain extent, but it cannot fully achieve optimization for any single objective; multi-objective optimization The model is not to consider the more optimization objectives, the more constraints, and the more complex the model, the better. An overly complex model will not only reduce the correctness and credibility of the model, but also cause a decrease in solution accuracy, an increase in calculation time, and data loss. Reduced storage space and transmission efficiency
[0014] 2) The optimization model is static and cannot meet the needs of intelligent dispatching of the power grid
[0015] Power grid operation data is dynamically changing, and the importance of multiple optimization objectives is also changing in different power grid states. In the above process, the requirements for intelligent grid dispatching management continue to increase, and it is objectively necessary to achieve a specific one under different operating states. Or the optimization of several objectives, the optimization model is a preset, static model, which cannot meet the demand for dynamic adjustment of the model due to real-time changes in the power grid state, and the existing unit combination mode cannot meet the requirements of intelligent dispatching
