Abstract: In comprehensive energy utilization, combined cooling, heat and power (CCHP) as an advanced distributed energy supply system has strong energy supply flexibility, so it is widely used in various energy supply occasions. The popularity of CCHP system brings information sharing and integration problems in multi-energy systems. To solve these problems, this paper develops a research of CCHP information model. Through an in-depth analysis of the composition, function and characteristics of CCHP system, by using the object oriented modeling method and following the common information model (CIM) extension rules, this paper establishes the information model of the CCHP system, presents the classes and their relationships, and illustrates its application and verifies its practicality by an example of CCHP.
