scope:

This part of IEC 61970, which is a technical specification on the CGMES, details the requirements of the exchange profiles belonging to the CGMES. The related technical information and documentation (i.e. RDFS, OCL, XMI and HTML) needed for the implementation of the CGMES, which is not copyrighted by either IEC or CENELEC, is available at the ENTSO-E web site (www.entsoe.eu).

The CGMES is defined using information on the Common Information Model (CIM) available in the public domain.

The CGMES is a superset of the former ENTSO-E CIM based data exchange standard (Profile 1) which was based on CIM14 (UML14v02) and has been used for certain network models exchanges since 2009. The CGMES reflects TSO requirements (as known by 2014) for accurate modelling of the ENTSO-E area for power flow, short circuit and dynamics applications whilst also allowing for the exchange of any diagram layouts including GIS data of a grid model.

Future editions of this technical specification will be released to describe following CGMES versions which reflect the additional requirements due to European network codes or guidelines.
