IEC 61968-11:2010

Application integration at electric utilities - System interfaces for distribution management - Part 11: Common information model (CIM) extensions for distribution

IEC 61968-11:2010(E) specifies the distribution extensions of the Common Information Model (CIM) specified in IEC 61970-301. It defines a standard set of extensions of common information model, which support message definitions in Parts 3 to 9 of IEC 61968, IEC 61968-13 and IEC 61968-14. The scope of this document is the information model that extends the base CIM for the needs of distribution networks, as well as for integration with enterprise-wide information systems typically used within electrical utilities. The information model is defined in UML which is platform-independent and electronically processable language that is then used to create message payload definitions in different required formats.

Intégration d'applications pour les services électriques - Interfaces système pour la gestion de la distribution - Partie 11: Extensions du modèle d'information commun (CIM) pour la distribution

La CEI 61968-11:2010(B) spécifie les extensions pour la distribution du modèle d'information commun (CIM - common information model) spécifié dans la CEI 61970-301. Elle définit un ensemble normalisé d'extensions du modèle d'information commun (CIM), qui prennent en charge les définitions de message données dans la CEI 61968-3 à la CEI 61968-9, la CEI 61968-13 et la CEI 61968-14. Le domaine d'application de la présente norme est le modèle d'information qui étend le CIM de base pour les besoins des réseaux de distribution, ainsi que pour l'intégration avec les systèmes d'information à l'échelle de l'entreprise qui sont typiquement utilisés dans les entreprises de distribution électrique. Le modèle d'information est défini en UML, langage indépendant de la plate-forme et pouvant être traité électroniquement, qui est alors utilisé pour créer les définitions de la charge utile de message dans différents formats requis.

Overview

IEC 61968-11:2010 - "Application integration at electric utilities - System interfaces for distribution - Part 11: Common information model (CIM) extensions for distribution" specifies the distribution-specific extensions to the IEC Common Information Model (CIM) defined in IEC 61970-301. The standard defines a platform‑independent, UML-based information model (often called DCIM) that supports message definitions used across IEC 61968 parts (Parts 3–9, 13 and 14). It is intended to produce electronically processable message payloads in different formats to enable consistent system interfaces for distribution management.

Key topics and technical requirements

• CIM extensions for distribution (DCIM): Defines classes and packages that extend the base CIM to represent distribution network objects and relationships.
• UML modeling: The information model is defined in UML to be platform‑independent and machine‑readable for generating message schemas.
• Package architecture: Normative package structure (top package IEC61968 with subpackages such as Common, WiresExt, Assets, AssetModels, Work, Customers, Metering, LoadControl, PaymentMetering).
• Electrical and physical modeling: Concepts separating electrical models (power system resources) from physical assets and locations to support accurate network representation.
• Distribution components modeled: Single‑phase and unbalanced loads, distribution line segments, conductors/cables, distribution transformers (including tap changers), and connectivity semantics.
• Metering and transacting: Models for metering, payment metering, transacting, receipting and tariff structures for integration with enterprise systems.
• Extensibility and message profile definitions: Guidance for extending the model and creating message profiles to meet utility-specific needs.
• Documentation artifacts: Detailed class, attribute and association tables and logical diagrams to support implementation.

Practical applications

• Distribution Management System (DMS) integration: Standardized data exchange between DMS and other systems (GIS, OMS, SCADA, ADMS).
• AMI / Metering and billing integration: Consistent representation of metering, payment metering and tariff information for billing and analytics.
• Asset and work management: Linking physical assets with power system resources for maintenance, outage and work-order workflows.
• Interoperability and data exchange: Enabling vendor-neutral interfaces and message payload generation for system-to-system communication in smart grid projects.
• Model-driven implementations: Use UML artifacts to generate XML/JSON/other schema payloads for APIs and middleware.

Who should use this standard

• Utility system architects and integrators
• Vendors of DMS, GIS, OMS, AMI and billing systems
• Software developers and data modelers implementing IEC 61968 interfaces
• Consultants and standards implementers working on smart grid interoperability

Related standards

• IEC 61970-301 - CIM (base standard)
• Other IEC 61968 parts - System interface message definitions (Parts 3–9, 13, 14)

Keywords: IEC 61968-11, CIM extensions for distribution, Common Information Model, DCIM, distribution management, UML, distribution network modeling, metering integration, system interfaces, smart grid interoperability.

Part 11: Common information model (CIM) extensions for distribution

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote

Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
