[0003] Most of the microgrids of industrial enterprises are complex energy systems based on industrial loads, including a variety of production capacity and energy-consuming equipment, and require high power supply and thermal reliability, but there are generally unreasonable industrial production structures, low energy utilization rates, and environmental pollution It is of great significance to optimize the energy consumption management of industrial enterprise microgrids, reduce operating costs and improve energy utilization.
[0004] At present, a variety of multi-energy collaborative optimization models for integrated energy systems have been proposed. Although these models can improve energy utilization efficiency more or less, they do not fully consider the cascade utilization of energy. Most of the industrial enterprise microgrid steam loads have demand Large and diverse characteristics, if the grade of steam heat energy is not fully considered, it will not be possible to recycle the remaining steam heat energy in the production process of industrial enterprises, and the energy utilization efficiency cannot be maximized, resulting in waste of energy in industrial enterprise microgrids
