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
