For an integrated energy system (IES) with demand-side response capabilities, both the production of chilled water, hot water, electricity, and steam can be changed by adjusting the output of various energy conversion equipment, and various energy products can be adjusted through the demand-side management. The change of energy conversion equipment operation and demand response measures implementation are all need costs. Integrated optimization of the production side and demand side of energy products such as cold, heat, electricity, and steam have the potential to reduce the total energy cost of IES. To this end, this article combines cases to establish a mathematical model for the various types of energy production and demand response costs of cold and heat electricity, with the goal of minimizing the overall cost of energy supply and use as a comprehensive control and optimization of energy supply and demand in IES. The results show that compared with simply adjusting the output of energy stations, the coordinated regulation of energy production and demand side of the integrated energy system has the potential to further reduce the cost of integrated energy supply and utilization system.
