The need to reform the energy system is urgent. Choose new energy to supplement traditional energy according to local conditions, to build a comprehensive energy system will become more and more emerging development areas of the rigid demand. However, in the practical application of RIES, due to its high complexity and wide range of involvement, there are information islands between various equipment and systems, which cannot support its high efficiency and timeliness. Therefore, The common information model (CIM) modeling method can break the information interaction barriers between RIES.Taking a new area as an example, the CIM model expansion of photovoltaic generating electricity system, wind power system, EV charging equipment, substation class, thermoelectric conversion equipment and user load is established. The classes and class attributes required for the information interaction of RIES control center in the new area were designed, which laid the foundation for the interaction between different energy systems and the load and storage of the source network.
