Full title and description

Application integration at electric utilities — System interfaces for distribution management — Part 11: Common information model (CIM) extensions for distribution (IEC 61968-11:2013). This part of IEC 61968 specifies the distribution extensions to the Common Information Model (CIM) defined in IEC 61970-301, providing a standardized information model for distribution network objects and for integration with enterprise systems used by electric utilities.

Abstract

IEC 61968-11:2013 defines a standard set of CIM extensions tailored to distribution networks to support message-based application integration across distribution management systems. The document provides UML-based information models that extend the base CIM, enabling consistent representations of distribution equipment, topology, single-line diagrams, naming and identification, and relationships needed to create interoperable message payloads for parts of the IEC 61968 series. Edition 2 updates and consolidates models for lines, transformers, switching devices, sensing equipment and other auxiliary components and introduces classes to improve object naming and diagram exchanges.

Scope

This standard specifies the distribution-specific extensions to the Common Information Model (CIM) defined in IEC 61970-301. Its scope covers the information model (expressed in UML) required to represent distribution network entities, their attributes and relationships, and to support the message definitions used across IEC 61968 parts that address distribution management interfaces. The document is intended to facilitate consistent data exchange between distribution management applications and enterprise systems by defining object classes, naming conventions, topology and diagram support, and payload structures that can be mapped into exchange formats.

Key topics and requirements

• Definition of CIM classes and attributes extending the IEC 61970 base model for distribution network elements (lines, transformers, switches, sensors, auxiliary equipment).
• Support for message definitions used in IEC 61968 parts (notably parts addressing application integration and message profiles) by providing a consistent information model.
• Introduction of classes to support flexible naming and identification of objects across systems.
• Classes and structures to support exchange of single-line diagrams and related diagrammatic topology information.
• Consolidation of transmission and distribution modelling where relevant, clarifying relationships and shared concepts.
• UML-based model definitions intended to be platform-neutral and processable for generating message payloads in required formats.
• Guidance on how the distribution extensions map to use cases for system interfaces and enterprise integration.

Typical use and users

IEC 61968-11 is used by utility architects, system integrators, software vendors, and implementers of Distribution Management Systems (DMS), Geographic Information Systems (GIS), outage and asset management systems, Advanced Distribution Management Systems (ADMS) and other enterprise applications that exchange distribution network data. It is used to design data models, generate message payloads, ensure interoperability between systems, and guide implementations that map local data structures to the CIM distribution extensions.

Related standards

This part is part of the IEC 61968 series and directly complements IEC 61970-301 (CIM base specification). It is intended to support message definitions used in IEC 61968 parts 3–9 and parts 13 and 14. Related and commonly referenced standards include other IEC 61968 parts (application integration/message profiles), IEC 61970 series (power system modelling and CIM), and standards for substation and device modelling such as IEC 61850 where cross-domain mappings are required.

FAQ

Q: What is this standard?

A: IEC 61968-11:2013 is the part of the IEC 61968 series that defines the Common Information Model (CIM) extensions required for electric distribution networks, enabling standardized information representation for application integration at utilities.

Q: What does it cover?

A: It covers the UML-based information model extensions to the CIM for distribution equipment, topology, single-line diagrams, identification and naming, and related constructs required to support IEC 61968 message definitions and enterprise integration scenarios.

Q: Who typically uses it?

A: Utility DMS/GIS architects, systems integrators, software vendors, implementers of ADMS/DMS/OMS/asset management systems, and consultants working on interoperability and data exchange solutions in the distribution domain.

Q: Is it current or superseded?

A: The 2013 document is Edition 2.0 and replaced the 2010 edition. It is published and intended for current use; users should check national adoption or newer amendments in their jurisdiction or from IEC for any updates beyond 2013 before implementation.

Q: Is it part of a series?

A: Yes — IEC 61968-11 is part of the IEC 61968 series (System interfaces for distribution management) and is aligned with the IEC 61970 CIM family (notably IEC 61970-301). It works together with other IEC 61968 parts that define message profiles and application interfaces.
