DIN EN 62325-450:2014-05

The common information model (CIM) is an abstract model that represents the entire major objects in an electric utility enterprise. The CIM IEC 62325 part 301 caters for the introduction of the objects required for the operation of electricity markets. It is important to note that the definition of a complete and detailed energy market model is beyond the scope of the series of standards IEC 62325 since energy markets do not necessarily have the same approaches to market operations. However, in relation to information interchange, an extensible and adaptable core set of information model definitions in UML can be defined. The information model definitions can be used as a controllable vocabulary to enable suppliers to interface with the market along with the use of standardized XML schema design rules to ensure consistent mapping between the UML model and the XML implementation schema as well as a uniform identification scheme. By providing a standard way of representing all these components as object classes and attributes, along with their relationships, the CIM facilitates the integration of market management system (MMS) applications developed independently by different vendors, between entire MMS systems, or between an MMS system and other systems concerned with different aspects of energy market operations. In particular, CIM enables the efficient integration of information interchanges between electricity market actors participating in various market business processes irrespective of the MMS system suppliers for each independent business process. The responsible body is DKE/K 952 "Netzleittechnik" ("Network control technology") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
