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

IEC 61970-600-1:2021 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.
This first edition cancels and replaces IEC TS 61970-600-1 published in 2017. This edition constitutes a technical revision.

Interface de programmation d'application pour système de gestion d'énergie (EMS-API) - Partie 600-1: Norme 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 ajoutées;
• les règles GENC3, GENC6, PROF2, PROF4, PROF5, PROF8, PROF9, EXCH5, EXCH6, EXCH7, MAS_4, MAS_6, MAS_9, MAS_10, MAS_11, MAS_13, EQ__1, HREF2, HREF3, HREF5, MVAL3, TPBD1, TPBD2, BPPL10, NAMC12 et NAMC13 ont été supprimées, car elles ne sont pas pertinentes du fait d'autres modifications;
• les règles suivantes ont été modifiées: GENC1, GENC2, GENC4, GENC5, GENC7, GENC8, GENC9, GENC10, GENC16, EQBD2, BPPL11, EXCH2, EXCH3, EXCH8, FBOD3, FBOD5, PROF10, PROF11, MAS_1, MAS_8, HGEN3, HREF1,EEXT1, EQ__2, TP__1, TP__2, TP__3, MARP10, MARP1

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.
---------------------- Page: 6 ----------------------
IEC 61970-600-1:2021 © IEC 2021 – 5 –

• Annex B on “Summary of specific rules for naming conventions” is deleted as the information

was either integrated in the UML or considered outdated.

• Annex D referring to the PST modelling is deleted as it will be fully integrated in

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,
EXCH9, TP__4 and MARP12 were added.
• Rules GENC3, GENC6, PROF2, PROF4, PROF5, PROF8, PROF9, EXCH5, EXCH6,
EXCH7, MAS_4, MAS_6, MAS_9, MAS_10, MAS_11, MAS_13, EQ__1, HREF2, HREF3,
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,
PROF10, PROF11, MAS_1, MAS_8, HGEN3, HREF1,EEXT1, EQ__2, TP__1, TP__2,
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.
The text of this International Standard is based on the following documents:
FDIS Report on voting
57/2366/FDIS 57/2382/RVD

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

identified needs that are not yet addressed.

instance file which is serialised according to IEC 61970-552
3.1.5
distribution

specific representation of a dataset. A dataset might be available in multiple serializations that

may differ in various ways, including natural language, media-type or format, schematic

organization, temporal and spatial resolution. The level of detail in the distribution is defined by

one or more profiles that the dataset conforms to
3.1.6
Common Grid Model Exchange Standard
CGMES

collection of standards defined in IEC 61970-600 series that support the exchange of power

system models (e.g. individual grid model or common grid model) between model authorities

(TSOs, DSOs, etc.) for the purpose of coordinated set of services to be performed on the same

model according to legislation or general data exchanges in the frame of system operation,

system development or utilities’ projects
3.1.7
European extensions

collection of classes, attributes and associations, which either extend or are defined in the

standard IEC CIM model (IEC 61970-300 series, IEC 91968-11 and IEC 62325-300 series). The

European extensions aim at satisfying requirements by the European legislation hence not

necessarily applicable to other continents. The worldwide adoption of these extensions may not

be exactly the same as the defined extension

3.1.8
external references resolved
no dangling references are present across the models of Model Authority Sets
3.1.9
header references resolved
references defined in model header are resolved
3.1.10
internal references resolved
no dangling references are present within the model of a Model Authority Set
3.1.11
merged model

model that is a union of different assembled models with external and header references

resolved
3.1.12
profile

data model to describe instance file for exchange of CIM data. A profile is a subset of classes,

associations and attributes needed to accomplish a specific type of interface and based upon

a CIM data model. Profiles may impose stricter rules on original classes and associations. A

profile is usually converted to schema (XSD, RDF, OWL, etc.) that can be used to create, read

and validate instance files for data exchange

Note 1 to entry: This term may be used to define either the semantic model for an instance data payload or the

syntactic schema for an instance data payload. A profile may be expressed in XSD, RDF, and/or OWL files. An

instance data conforming to a profile can be tested in exchanges between applications. A profile is necessary in

order to “use” the canonical model.
