ENTSO-ECommon Grid Model Exchange Standard (CGMES) Library
The CGMES Library contains all the documents approved by ENTSO-E or IEC for the harmonisation and implementation of standards related to CGMES in both system operation and system development areas. Therefore provided documentation enables exchanges for the data necessary for regional or pan-European grid development studies, and for system operation processes required from the network codes. For any maintenance request on ENTSO-E documents, please use the maintenance request form and send it to cim@entsoe.eu

Dynamics: IEC 61970-302 and IEC 61970-457
In 2024, the International Electrotechnical Commission (IEC) published new versions of the documents supporting the information exchange of models between software applications that perform analysis of the steady-state stability (small-signal stability) or transient stability of a power system.
Both the Dynamics profile and the specification document were updated in the IEC 61970-457:2024 and IEC 61970-302:2024 respectively.
Such update is not yet included as part of the CGMES series of standards.
