IEC 62325-451-3:2014

Framework for energy market communications - Part 451-3: Transmission capacity allocation business process (explicit or implicit auction) and contextual models for European market

IEC 62325-451-3:2014 specifies a package for the transmission capacity allocation business process through explicit or implicit auctions and the associated document contextual models, assembly models and XML schema for use within European style markets. This International standard is based on the European style market contextual model (IEC 62325-351). 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 these business processes. The contextualised ABIEs have been assembled into the relevant document contextual models.

Cadre pour les communications pour le marché de l'énergie - Partie 451-3: Processus métier d'attribution de la capacité de transport (vente aux enchères explicite ou implicite) et modèles contextuels pour le marché européen

L'IEC 62325-451-3:2014 spécifie un paquetage pour le processus métier d'attribution de la capacité de transport par ventes aux enchères explicites ou implicites et les modèles contextuels de document, modèles d'assemblage et schéma XML associés à utiliser sur les marchés de style européen. La présente Norme internationale est basée sur le modèle contextuel de marché de style européen (IEC 62325-351). 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 ces processus métier. Les ABIE contextualisées ont été assemblées dans les modèles contextuels de document pertinents.
