Energy management system application program interface (EMS-API) - Part 456: Solved power system state profiles
IEC 61970-456:2013 defines the subset of classes, class attributes, and roles from the CIM necessary to describe the result of state estimation, power flow and other similar applications that produce a steady-state solution of a power network, under a set of use cases which are included informatively in this standard. This standard is intended for two distinct audiences, data producers and data recipients, and may be read from those two perspectives. From the standpoint of model export software used by a data producer, the standard describes how a producer may describe an instance of a network case in order to make it available to some other program. From the standpoint of a consumer, the standard describes what that importing software must be able to interpret in order to consume solution cases.
Interface de programmation d'application pour système de gestion d'énergie (EMS-API) - Partie 456: Profils d'état de réseaux électriques résolus
La CEI 61970-456:2013 définit le sous-ensemble de classes, les attributs de classe et les rôles du CIM, nécessaires pour décrire le résultat de l'estimation d'état, du calcul de répartition et d'autres applications similaires produisant une solution en régime établi d'un réseau électrique dans un ensemble de cas d'utilisation inclus à titre informatif dans la présente norme. La présente norme vise deux publics différents, les producteurs de données et les utilisateurs de données. Elle peut être lue de ces deux points de vue. Du point de vue du logiciel d'exportation de modèles utilisé par un producteur de données, la présente norme présente la façon dont un producteur peut décrire une instance d'un cas de réseau pour le rendre accessible à un autre programme. Du point de vue du client, la présente norme décrit ce que ce logiciel d'importation doit être capable d'interpréter afin de pouvoir absorber les cas de solution du client.

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 effort
