Problems solved by technology

[0003] The energy prediction in the prior art, whether it is a linear model or a nonlinear model, cannot be fully adapted due to the irregularity of the basic data, and because the weights and thresholds of various neural networks may not necessarily be trained to the optimal value, resulting in a single load forecasting algorithm with poor forecasting accuracy and large forecast deviations, which is not conducive to later scheduling optimization
[0004] Aiming at the above problems existing in the prior art, no effective solution has been found yet
