Summary In order to solve the problem of low utilization efficiency and high operating cost of a single energy system among various types of energy, a comprehensive energy system was constructed, which considering P2G equipment, CCHP co‐generation equipment, electric refrigerators, and other multi‐source systems. Based on the design of the multi‐source collaborative optimization operation structure of the integrated energy system, multiple objective functions are set, including the maximization of investment return rate, the maximization of carbon emission reduction rate, and the minimization of energy abandonment rate. The calculation example analysis shows that when multi‐energy energy conversion equipment participates in the system for coordinated operation, it will cause the depreciation cost of the unit to increase continuously, resulting in a certain increase in the net benefit of the integrated energy system. In addition, electrical conversion equipment can effectively reduce waste energy and improve the effective utilization of clean energy, thereby increasing the carbon emission reduction rate. The results of the calculation examples effectively verify that optimizing energy conversion efficiency has a positive effect on alleviating clean energy consumption.
