Framework for energy market communications - Part 451-8: HVDC processes, contextual and assembly models for European style market

This part of IEC 62325 specifies a UML package for the HVDC Link scheduling business
process and its associated document contextual models, assembly models and XML schemas
for use within the European style electricity markets.
This part of IEC 62325 is based on the European style market contextual model
(IEC 62325-351). The business process covered by this part of IEC 62325 is described in
Subclause 5.3.
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 the European style market HVDC Link scheduling business process.

Kommunikation im Energiemarkt – Teil 451-8: Hochspannungsgleichstrom (HGÜ)- Prozesse, Kontextbezogene Modelle und Einbindungsmodelle für den europäischen Markt

Cadre pour les communications pour le marché de l'énergie - Partie 451-8: Processus de programmation de liaisons HVDC, modèles contextuels et modèles d'assemblage pour le marché de style européen

IEC 62325-451-8:2022 spécifie un paquetage UML (Unified Modelling Language) pour le processus métier de programmation de liaisons HVDC ainsi que les modèles contextuels de document, les modèles d'assemblage et les schémas XML associés à appliquer au sein des marchés de l'électricité de style européen. La présente partie de l'IEC 62325 s'appuie sur le modèle contextuel pour les marchés de style européen (IEC 62325-351). Le processus métier couvert par la présente partie de l'IEC 62325 est décrit en 5.3. Les composants de base agrégés (ACC, Aggregate Core Component) pertinents définis dans l'IEC 62325-351 ont été contextualisés sous la forme d'entités d'information métier agrégées (ABIE, Aggregated Business Information Entity) afin de satisfaire aux exigences du processus métier de programmation de liaisons HVDC sur les marchés de style européen.

Part 451-8: HVDC Scheduling process, contextual and assembly
models for European style 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.

IEC 62325-451-8 has been prepared by IEC technical committee 57: Power systems

INTRODUCTION

This document is one part of the IEC 62325 series for deregulated energy market data

exchanges based on the European style market profile. This part of IEC 62325 defines the

document contextual models, the message assembly models as well as the XML schemas to

be used for the HVDC Link Scheduling process.

The principal objective of the IEC 62325 series is to produce standards which facilitate the

integration of market application software developed independently by different vendors into a

market management system, between market management systems and market participant

systems. This is accomplished by defining message exchanges to allow these applications or

systems access to public data and
