IEC 61970-301:2013 ED4

Energy management system application program interface (EMS-API) - Part 301: Common information model (CIM) base

Scope

IEC 61970-301:2013 deals with the common information model (CIM), an abstract model that represents all the major objects in an electric utility enterprise typically involved in utility operations. The object classes represented in the CIM are abstract in nature and may be used in a wide variety of applications. The use of the CIM goes far beyond its application in an EMS. This standard is to be understood as a tool to enable integration in any domain where a common power system model is needed to facilitate interoperability and plug compatibility between applications and systems independent of any particular implementation. Major changes from the third edition include the following:
- extensions have been added to support UCTE exchange;
- the transformer regulation model has been expanded to support phase shifting transformer models needed by ENTSO-E;
- zero and negative sequence impedance terms have been added;
- new StateVariables package has been added;
- additional classes have been added.
