With the continuous development of the integrated energy system, how to further improve the economic and environmental benefits of the integrated energy system is an important research content of the integrated energy system. In addition to the large amount of carbon emissions in each power generation unit, there are also large amounts of carbon emissions in the production, construction and transportation of new energy units and electric energy storage equipment, which should also be included in the total carbon emissions of the system. For this reason, this paper analyzes the carbon emissions of each unit of the system based on the integrated energy system with electric heating load demand, and uses the life cycle method to analyze the carbon generated during the production, construction and transportation of new energy units and electric energy storage equipment in the integrated energy system. Emissions are introduced into the economic decision-making indicators of the integrated energy system jointly with carbon rights trading, and the system model is solved through CPLEX. Finally, a comparative analysis of two calculation examples of the integrated energy system, whether the carbon emissions of wind power and electric energy storage equipment are taken into account, is compared and analyzed. The results show that the introduction of life cycle law and carbon rights trading into the integrated energy system can promote the low-carbon development of the integrated energy system.
