Energy management system application program interface (EMS-API) - Part 600-1: Common Grid Model Exchange Specification (CGMES) - Structure and rules

This part of IEC 61970, which covers the definition of Common Grid Model Exchange Standard
(CGMES), defines the main rules and application’s requirements to meet business requirements
for assembled and merged model to fit relevant business services. This document does not
define the business requirements, business processes nor how applications are implemented.
This document defines how relevant Common Information Model (CIM) standards work together
so that specific business requirements can be resolved.
It also includes extensions to the Common Information Model (CIM). The current extensions are
defined in IEC 61970-301:2020 and will be covered in its future Amendment 1, but additional
extensions can be defined in other standards in the IEC 61970-600-series. The extensions can
be used to define additional profiles or to expand IEC 61970-450-series or IEC 61968-13
profiles. However, primary CGMES includes additional constraints on existing profiles and
validation of assembled and merged models that is based on existing profiles. This can be done
by making optional attributes and associations mandatory (required).
In addition, this document includes the specification of the serialisation that must be supported
by referring to an existing standard defined in IEC 61970-550-series, e.g., IEC 61970-552, and
making relevant constraints related to it.
The goal is to achieve interoperability between applications using CGMES in a highperformance
environment with combined minimum effort so that relevant business processes
are satisfied.
An overview of IEC 61970-600 series is provided in the following table, which also presents
identified needs that are not yet addressed.

Schnittstelle der Anwendungsprotokolle von Energieverwaltungssystemen (EMS-API) - Teil 600-1: Spezifikation für den Austausch von Elektrizitätsversorgungssystemmodellen (CGMES) - Strukturen und Regeln

Interface de programmation d'application pour système de gestion d'énergie (EMS-API) – Partie 600-1: Spécification pour l'échange de modèle de réseau commun (CGMES) – Structure et règles

IEC 61970-600-1:2021 couvre la définition de la norme pour l'échange de modèle de réseau commun (CGMES), définit les principales règles et exigences d'application qui visent à satisfaire aux exigences métier destinées à adapter le modèle assemblé et fusionné aux services métier correspondants. Le présent document ne définit pas les exigences métier, les processus métier ni la façon dont les applications sont mises en œuvre. Le présent document définit la façon dont les normes applicables du modèle d'information commun (CIM) fonctionnent ensemble pour pouvoir répondre aux exigences métier spécifiques.
Il comprend également des extensions du modèle d'information commun (CIM). Les extensions actuelles sont définies dans l'IEC 61970-301:2020 et seront traitées dans son futur Amendement 1, mais des extensions supplémentaires peuvent être définies dans d'autres normes de la série IEC 61970-600. Les extensions peuvent être utilisées pour définir des profils supplémentaires ou pour étendre les profils de la série IEC 61970-450 ou de l'IEC 61968-13. Toutefois, la CGMES primaire inclut des contraintes supplémentaires pour les profils existants et la validation des modèles assemblés et fusionnés qui repose sur les profils existants. Pour cela, les attributs et les associations facultatifs peuvent être rendus obligatoires.
En outre, le présent document comprend la spécification de la sérialisation qu'il importe d'étayer par une référence à une norme existante définie dans la série IEC 61970-550, par exemple l'IEC 61970-552, et par l'établissement de contraintes pertinentes associées.
L'objectif est d'assurer l'interopérabilité entre les applications qui utilisent la CGMES dans un environnement à haute performance en combinant un effort minimal pour satisfaire aux processus métier correspondants.
Cette première édition annule et remplace l'IEC TS 61970-600-1 parue en 2017. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'IEC TS 61970 600-1:2017:
• les termes et définitions ont été mis à jour;
• la colonne "Type" a été supprimée de tous les tableaux pour améliorer la lisibilité du document. Toutes les règles sont en effet réputées nécessaires, ce qui rend inutile leur catégorisation;
• l'exigence HGEN4 a été ajoutée afin de définir des règles supplémentaires dans l'en-tête de fichier par rapport à l'IEC 61970-552:2016;
• l'Annexe B qui récapitule les règles spécifiques pour les conventions de nommage a été supprimée, car les informations étaient soit intégrées au modèle UML, soit jugées obsolètes;
• l'Annexe D qui traite de la modélisation des transformateurs déphaseurs (PST) a été supprimée, car elle sera entièrement intégrée à l'IEC 61970 301:2020+AMD1 ;
• l'Annexe E qui fournit un guide de mise en œuvre a été supprimée, car toutes les règles et recommandations de mise en œuvre sont ou seront intégrées à l'Article 5 du présent document ou dans l'IEC 61970-301:2020 (et son futur Amendement 1), l'IEC 61970-452 ou l'IEC 61970-456, comme cela est indiqué dans le présent document. Noter que l'ancien E.11.2 qui traite des attributs ConformLoadGroup et NonConformLoadGroup a été organisé d'une manière différente en raison d'un autre problème. Pour plus d'informations, se référer à l'IEC 61970-600-2:2020;
• les règles GENC17, GENC18, GENC19, EQ__4, EQ__5, SV__4, BPPL12, BPPL13, MVAL5, EXCH9, TP__4 et MARP12 ont été

Part 600-1: Common Grid Model Exchange Standard (CGMES) –
Structure and rules

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.
International Standard IEC 61970-600-1 has been prepared by IEC technical committee 57:
Power systems management and associated information exchange.
This first edition cancels and replaces IEC TS 61970-600-1 published in 2017. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to
IEC TS 61970-600-1:2017:
• Terms and definitions were updated.
• The “Type” column in all tables was deleted to increase readability of the document as all
the rules are considered required, hence categorisation is not necessary.
• Requirement HGEN4 was added to define additional rules to the file header compared to
IEC 61970-552:2016.

IEC 61970-301:2020+AMD1 .
• Annex E “Implementation guide” is deleted as all rules and implementation guidance is or
will be integrated in either Clause 5 of this document or IEC 61970-301:2020 (and its future
Amendment 1) or IEC 61970-452 or IEC 61970-456 as referenced by this document. Note
that former Subclause E.11.2 on ConformLoadGroup and NonConformLoadGroup was
implemented differently due to another issue, please refer to IEC 61970-600-2:2020.
• Rules GENC17, GENC18, GENC19, EQ__4, EQ__5, SV__4, BPPL12, BPPL13, MVAL5,

HREF5, MVAL3, TPBD1, TPBD2, BPPL10, NAMC12 and NAMC13 are deleted as they are
considered not relevant due to other changes.
• The following rules were modified: GENC1, GENC2, GENC4, GENC5, GENC7, GENC8,
GENC9, GENC10, GENC16, EQBD2, BPPL11, EXCH2, EXCH3, EXCH8, FBOD3, FBOD5,

TP__3, MARP10, MARP11, NAMC1, NAMC4, NAMC11, NAMC14, BPPL1, BPPL2 and
BPPL3.
• Explicit equipment boundary profile definition (EQBD) has been deprecated (refer to
Subclause 4.6.5 of IEC 61970-301:2020 and future Amendment 1 for details on
deprecations) in this edition in favour of using its full profile counterpart (EQ) for exchange
of boundary datasets. The topology boundary profile (TPBD) is not included in the CGMES
as TP is considered output and therefore it is no need to exchange Topology information
part of the boundary model authority set.
• Annex F has been deleted.

INTRODUCTION
The purpose of this document is to define the Common Grid Model Exchange Standard
(CGMES) based on Common Information Model (CIM) standards defined in IEC 61970-series,
IEC 61968-series and IEC 62325-series and to address requirements defined by the European
legislation. However, the document is not limited to the European legislation requirements and
business processes, it is created to support data exchange between applications that support
power system model management and analysis. The data exchange can be between internal
applications or between applications at System Operators (SO) and Reginal Coordination
Centre (RCC). This covers DSO-DSO, DSO-TSO, TSO-TSO, TSO-RCC/ISO/RTO and RCC-
RCC interfaces, but not limited to these.
The CGMES is created to address the information exchange requirements provided in Common
Grid Model methodologies (CGMm) in accordance with the legal requirements stated in various
European network codes guidelines. The CGMES applies to applications dealing with power
system data management, as well as applications supporting the following analyses:
• power flow and contingency analyses,
• short circuit calculations,
• market information and transparency,
• capacity calculation for capacity allocation and congestion management, and
• dynamic security assessment.
The conformity of applications used for system operation and system development data
exchanges with the CGMES is crucial for the needed interoperability of these applications. This
document provides the grouping of all principle requirements for the CGMES Conformity
Assessment Framework and the guiding principles for assessing applications’ CGMES
conformity. The description of the CGMES Conformity Assessment Process is currently not part
of the IEC 61970-600-series, but it is planned to be included as an international standard in
order to validate that the CGMES is correctly implemented by suppliers of the applications used
by system operators (ISO/TSO/DSO etc) and for Regional Coordination Centres (RCCs).

Part 600-1: Common Grid Model Exchange Standard (CGMES) –
Structure and rules



1 Scope
This part of IEC 61970, which covers the definition of Common Grid Model Exchange Standard
(CGMES), defines the main rules and application’s requirements to meet business requirements
for assembled and merged model to fit relevant business services. This document does not
define the business requirements, business processes nor how applications are implemented.
This document defines how relevant Common Information Model (CIM) standards work together
so that specific business requirements can be resolved.
It also includes extensions to the Common Information Model (CIM). The current extensions are
defined in IEC 61970-301:2020 and will be covered in its future Amendment 1, but additional
extensions can be defined in other standards in the IEC 61970-600-series. The extensions can
be used to define additional profiles or to expand IEC 61970-450-series or IEC 61968-13
profiles. However, primary CGMES includes additional constraints on existing profiles and
validation of assembled and merged models that is based on existing profiles. This can be done
by making optional attributes and associations mandatory (required).
In addition, this document includes the specification of the serialisation that must be supported
by referring to an existing standard defined in IEC 61970-550-series, e.g., IEC 61970-552, and
making relevant constraints related to it.
The goal is to achieve interoperability between applications using CGMES in a high-
performance environment with combined minimum effort so that relevant business processes
are satisfied.
An overview of IEC 61970-600 series is provided in the following table, which also presents
