scope:

This part of IEC 61968 specifies profiles that can be used to exchange Network Models in a Utility or between a Utility and external applications to the utility. This document provides a list of profiles which allow to model balanced and unbalanced distribution networks in order to conduct network analysis (Power flow calculation). Therefore, it leverages already existing profiles (IEC 61970-45x based on IEC 61970-301 (CIM base) or profiles based on IEC 6196811 CIM extension for Distribution). This document reuses some profiles without any change, or eventually extends them or restricts them. Moreover, it proposes other profiles to reflect Distribution needs.

Use of CIM in Distribution is not a new topic. Several documents can be of interest [13][17][18][19][20]. This document includes informative parts, as CIM model extensions, which could be integrated in future versions of the IEC CIM Model. These extensions have been used by some utilities for utility internal information exchange use cases and to support information exchanges between different market participants like Transmisstion System Operators (TSO), Distributed System Operators (DSO), Distributed Network Operators (DNO) and Significant Grid Users (SGU) including generators and industry (see Annex J for example).
