IEC 62325-451-4:2017

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

IEC 62325-451-4:2017 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.
This new edition includes the following significant technical changes with respect to the previous edition:
- removal of the attributes “quantity” and “secondary quantity” of the class “Point”;
- introduction of the classes “Quantity” and "Reason" from IEC 62351-351 UML package.

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.
