Framework for energy market communications - Part 451-4: Settlement and reconciliation business process, contextual and assembly models for European market

Based on the European style market profile (ESMP) (IEC 62325-351), this part of IEC 62325-
451 specifies a package for the settlement and reconciliation business process and the
associated document contextual model, assembly model and XML schema for use within
European style markets.
The relevant aggregate core components (ACCs) defined in IEC 62325-351 have been
contextualised into aggregated business information entities (ABIEs) to satisfy the
requirements of this business process. The contextualised ABIEs have been assembled into
the relevant document contextual models. Related assembly models and XML schema for the
exchange of information between market participants are automatically generated from the
assembled document contextual models.
This part of IEC 62325 provides a uniform layout for the transmission of aggregated data in
order to settle the electricity market. It is however not the purpose of this document to define
the formula to be taken into account to settle or reconcile a market. The purpose of this
document is only to enable the information exchange necessary to carry out the computation
of settlement and reconciliation.
The settlement process or reconciliation process is the way to compute the final position of
each market participant as well as its imbalance amounts.

Kommunikation im Energiemarkt - Teil 451-4: Abwicklungs- und Abstimmungsgeschäftsprozesse, kontextbezogene Modelle und Einbindungsmodelle für den europäischen Markt

Cadre pour les communications pour le marché de l'énergie – Partie 451-4: Processus métier de règlement des écarts et de réconciliation, modèles contextuels et modèles d’assemblage pour le marché européen

IEC 62325-451-4:2017 spécifie un paquetage pour les processus métier de règlement des écarts et de réconciliation et le modèle contextuel de document, modèle d'assemblage et schéma XML associés à utiliser sur les marchés de style européen. Les composants de base agrégés (ACC, Aggregate core components) pertinents définis dans l’IEC 62325-351 ont été contextualisés en entités d’information métier agrégées (ABIE – aggregated business information entities) afin de satisfaire aux exigences de ce processus métier. Les ABIE contextualisées ont été assemblées dans les modèles contextuels de document pertinents. Des modèles d'assemblage et un schéma XML associés pour l'échange d’informations entre les participants au marché sont générés automatiquement à partir des modèles contextuels de document assemblés. La présente partie de l’IEC 62325 fournit un format uniforme pour la transmission des données agrégées en vue de régler le marché de l’électricité. Le présent document n'a cependant pas pour objet de définir les formules à prendre en compte pour le règlement des écarts ou la réconciliation d’un marché. Il a seulement pour objet de permettre l’échange d’informations nécessaires au calcul relatif au règlement des écarts et de réconciliation. Le processus de règlement des écarts ou le processus de réconciliation permet de calculer la position finale de chaque participant au marché ainsi que ses montants de déséquilibre. Cette deuxième édition annule et remplace la première édition parue en 2014. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: - Retrait des attributs « quantity » et « secondary quantity » de la classe « Point »; - Introduction de la classe « Quantity » et « Reason » du paquetage UML de l’IEC 62351-351.

Okvir za komunikacije na trgu z električno energijo - 451- 4. del: Poslovni proces za dogovor in uskladitev, kontekstni in združevalni modeli evropskega trga

Na podlagi profila za evropski trg (ESMP) (IEC 62325-351) ta del standarda IEC 62325-451 določa paket poslovnih procesov za dogovor in uskladitev ter povezani kontekstualni model dokumentov, model sestavljanja in shemo XML za uporabo na evropskih trgih.
Ustrezne združene osrednje komponente (ACC), opredeljene v standardu IEC 62325-351, so bile kontekstualizirane v združene entitete poslovnih informacij (ABIE), da ustrezajo zahtevam za ta poslovni proces. Te kontekstualizirane entitete so bile zbrane v ustreznih kontekstualnih modelih dokumentov. Ustrezni modeli sestavljanja in shema XML za izmenjavo informacij med udeleženci na trgu se samodejno ustvarijo iz kontekstualnega modela zbranih dokumentov.
Ta del standarda IEC 62325 določa enotno razporeditev za prenos združenih podatkov za dogovor na trgu z električno energijo. Vendar pa namen tega dokumenta ni opredelitev formule, ki se upošteva pri dogovoru ali uskladitvi na trgu. Namen tega dokumenta je zgolj omogočanje izmenjave informacij, potrebnih za izračun dogovora in uskladitve.
Proces za dogovor ali uskladitev je način za izračun končnega položaja posameznega udeleženca na trgu in obsega neravnotežja.

FRAMEWORK FOR ENERGY MARKET COMMUNICATIONS –
Part 451-4: Settlement and reconciliation business process,
contextual and assembly models for European market
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 62325-451-4 has been prepared by IEC technical committee 57:

Power systems management and associated information exchange.

This second edition cancels and replaces the first edition published in 2014. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

a) Removal of the attributes “quantity” and “secondary quantity” of the class “Point”;

b) Introduction of the class “Quantity” from IEC 62351-351 UML package, with the following

attributes “quantity” as mandatory and “quality” as optional, and create two association

1..1 between the class “Quantity” and the class “Point” with the role “In_Quantity” and

“Out_Quantity”.

c) Introduction of the class “Reason” from IEC 62351-351 UML package, with the following

attributes “code” as mandatory and “text” as optional, and create an association 0..* from

the class “Reason” to the class “Point” with the role “Reason”.
