This International Standard specifies the distribution extensions of the Common Information Model (CIM) specified in EN 61970-301. It defines a standard set of extensions of common information model (CIM), which support message definitions in Parts 3 to 9 of EN 61968, EN 61968-13 and EN 61968-14. The scope of this document is the information model that extends the base CIM for the needs of distribution networks, as well as for integration with enterprise-wide information systems typically used within electrical utilities. The information model is defined in UML which is platform-independent and electronically processable language that is then used to create message payload definitions in different required formats. In this way, this standard will not be impacted by the specification, development and/or deployment of next generation infrastructures, either through the use of standards or proprietary means.
