Problems solved by technology
[0004] The inventors of the present application found that for the optimal scheduling of the integrated energy system, most of the existing technologies are based on the principle of economical optimization, while the characteristics of the demand on the load side, that is, the coordination between the resources on the demand side of the integrated energy system and the energy-using system The matching relationship is less considered
Moreover, the existing technology does not consider the impact of the cooling and heating loads stored in the building itself, and there are certain deficiencies in optimal scheduling
