Framework for energy market communications - Part 450: Profile and context modelling rules

This part of IEC 62325 defines how to create a profile from the common information model and the context modelling rules related to this task. This standard is to be applied to IEC 62325 series. An harmonised standard, IEC 62361-101, is presently under development, which will supersede this current standard. The common information model (CIM) is an abstract model that represents all the major objects in an electric utility enterprise. The CIM IEC 62325-301 caters for the introduction of the objects required for the operation of electricity markets. It is important to note that the definition of a complete and detailed energy market model is beyond the scope of the IEC 62325 series standards since energy markets do not necessarily have the same approach to market operations. However, in relation to information interchange, an extensible and adaptable core set of information model definitions in UML can be defined. The information model definitions can be used as a controlled vocabulary to enable utilities to interface with the market along with the use of standardised XML schema design rules to ensure consistent mapping between the UML model and the XML implementation schema as well as a uniform identification scheme. By providing a standard way of representing all these components as object classes and attributes, along with their relationships, the CIM facilitates the integration of market management system (MMS2) applications developed independently by different vendors, between entire MMS systems, or between an MMS system and other systems concerned with different aspects of energy market operations. In particular, CIM enables the efficient integration of information interchanges between electricity market actors participating in various market business processes irrespective of the MMS system supplier for each independent business process. The CIM facilitates integration by defining a common language (i.e. semantics and syntax) based on the CIM to enable these applications or systems to access public data and exchange information without depending on the internal representation of the information. This document provides the modelling rules necessary to ensure that contextual models derived from the CIM are in conformity with the CIM model. It ensures modelling consistency and avoids ambiguity between objects by providing a clear understanding on what they are based within the CIM.

Kommunikation im Energiemarkt - Teil 450: Profil- und Kontext-Modellierungsregeln

Cadre pour les communications pour le marché de l'énergie - Partie 450: Règles de modélisation de profils et de contextes

La CEI 62325-450:2013 définit comment créer un profil à partir du modèle d'information commun et des règles de modélisation de contexte relatives à cette tâche. La présente norme est à appliquer à la série de normes CEI 62325. Le modèle d'information commun (CIM) est un modèle abstrait qui représente tous les objets principaux d'une entreprise de service public de distribution d'électricité. La partie 301 de la CEI 62325 (CIM) traite de l'introduction des objets exigés pour l'exploitation des marchés de l'électricité.

Ogrodje za komunikacije na trgu z električno energijo - 450. del: Pravila za oblikovanje profila in konteksta (IEC 62325-450:2013)

Ta del standarda IEC 62325 opredeljuje način oblikovanja profila na podlagi skupnega informacijskega modela in pravil za oblikovanje konteksta, povezanih s to nalogo. Ta standard se uporablja za skupino standardov IEC 62325. Trenutno se pripravlja harmonizirani standard IEC 62361-101, ki bo nadomestil veljavni standard. Skupni informacijski model (CIM) je abstraktni model, ki predstavlja vse glavne objekte v javnem elektro podjetju. CIM IEC 62325-301 zagotavlja uvedbo objektov, potrebnih za delovanje trgov z električno energijo. Opozoriti je treba, da opredelitev popolnega in podrobnega modela trga z električno energijo presega področje uporabe skupine standardov IEC 62325, ker trgi z električno energijo nimajo nujno enakega pristopa k delovanju trga. Vendar je v zvezi z izmenjavo informacij mogoče opredeliti razširljiv in prilagodljiv temeljni sklop definicij informacijskega modela v UML. Definicije informacijskega modela je mogoče uporabiti kot nadzorovan slovar, da se elektropodjetjem omogoči povezovanje s trgom poleg uporabe standardiziranih pravil za zasnovo sheme XML, da se zagotovi skladno mapiranje med modelom UML in implementacijsko shemo XML ter tudi enotna identifikacijska shema. Z zagotavljanjem standardnega načina predstavitve vseh teh sestavnih delov kot objektnih razredov in atributov, skupaj z njihovimi povezavami, CIM pospešuje integracijo aplikacij sistema za upravljanje trga (MMS2), ki so jih neodvisno razvili različni prodajalci, med celotnimi sistemi MMS ali med sistemom MMS in drugimi sistemi, ki se osredotočajo na različne vidike delovanja trga z električno energijo. CIM omogoča zlasti učinkovito integracijo izmenjav informacij med udeleženci na trgu z električno energijo, ki sodelujejo v različnih tržnih poslovnih procesih ne glede na dobavitelja sistema MMS za vsak neodvisen poslovni proces. CIM pospešuje integracijo z opredelitvijo skupnega jezika (tj. semantike in sintakse), osnovanega na CIM, ki omogoča, da imajo te aplikacije ali sistemi dostop do javnih podatkov in izmenjujejo informacije neodvisno od tega, kako so te informacije izražene interno. Ta dokument zagotavlja pravila za oblikovanje, potrebna za zagotavljanje, da so kontekstualni modeli, izvedeni iz CIM, v skladu z modelom CIM. Zagotavlja skladnost oblikovanja in preprečuje dvoumnost med objekti z zagotavljanjem jasnega razumevanja, na čem temeljijo v okviru CIM.

Part 450: Profile and context modelling rules

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.

INTRODUCTION
This standard is one of the IEC 62325 series which define protocols for deregulated energy
market communications.
The principal objective of the IEC 62325 series of standards 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 enable
these applications or systems access to public data and exchange information independent of
how such information is represented internally.
1
The common information model (CIM ) specifies the basis for the semantics for this message
exchange.
The profile specifications specify the content of the messages exchanged. This document
provides the profile and context modelling rules for these message profile specifications that
support the design of all electricity markets.

FRAMEWORK FOR ENERGY MARKET COMMUNICATIONS –

Part 450: Profile and context modelling rules



1 Scope
This part of IEC 62325 defines how to create a profile from the common information model
and the context modelling rules related to this task.
This standard is to be applied to IEC 62325 series. An harmonised standard, IEC 62361-101,
is presently under development, which will supersede this current standard.
The common information model (CIM) is an abstract model that represents all the major
objects in an electric utility enterprise. The CIM IEC 62325-301 caters for the introduction of
the objects required for the operation of electricity markets.
It is important to note that the definition of a complete and detailed energy market model is
beyond the scope of the IEC 62325 series standards since energy markets do not necessarily
have the same approach to market operations.
However, in relation to information interchange, an extensible and adaptable core set of
information model definitions in UML can be defined. The information model definitions can be
used as a controlled vocabulary to enable utilities to interface with the market along with the
use of standardised XML schema design rules to ensure consistent mapping between the
UML model and the XML implementation schema as well as a uniform identification scheme.
By providing a standard way of representing all these components as object classes and
attributes, along with their relationships, the CIM facilitates the integration of market
2
management system (MMS ) applications developed independently by different vendors,
between entire MMS systems, or between an MMS system and other systems concerned with
different aspects of energy market operations. In particular, CIM enables the efficient
integration of information interchanges between electricity market actors participating in
various market business processes irrespective of the MMS system supplier for each
independent business process.
The CIM facilitates integration by defining a common language (i.e. semantics and syntax)
based on the CIM to enable these applications or systems to access public data and
exchange information without depending on the internal representation of the information.
This document provides the modelling rules necessary to ensure that contextual models
derived from the CIM are in conformity with the CIM model.
It ensures modelling consistency and avoids ambiguity between objects by providing a clear
understanding on what they are based within the CIM.

4.1 The two methods used to generate profiles
There are at least two methods currently used to generate contextual profiles and message
generation and assembly. Figure 1 presents the two methods.
IEC  790/13

Figure 1 – Differences between European and American approach
This document is primarily concerned with the profile and contextual modelling rules using the
European path; however, there is nothing in this document that would prohibit the use of the

---------------------- Page: 15 ----------------------

– 10 – 62325-450 © IEC:2013
American path. The rules defined within this document do not preclude the use of either path
shown in the figure above and any conflicts are unintentional. In the event a rule exists that
precludes the use of either path, that rule should be considered invalid and will be removed
from this document in future revisions.
From an UML or OWL profile, the transforming rules to generate a XSD schema shall comply
with IEC 62361-100.
4.2 Overview
IEC  791/13

Figure 2 – Modelling framework principles
The basic principle underlying the modelling of different regional contextual models and their
subsequent contextualized documents for information exchange is based on the scheme
outlined in Figure 2.
4
At the top of the figure the common information model (CIM ) provides the overall semantic
model for the electricity industry and covers both power system component and market
information interchange requirements. IEC 62325-301 extends the original CIM in order to
meet market needs for information interchange between actors participating in various market
business processes. The CIM is therefore, the basis on which all information interchange
requirements are built independently of the regional contextual model being used.

SIST EN 62325-450:2013
62325-450 © IEC:2013 – 11 –
From the CIM, regional contextual models are built to cover the market information
interchange requirements for a given Region (i.e. the Business Context).
A region may be a continent where common electricity market designs are used for the
exchange of information (Europe, North America, Asia, etc.). It may also be a specific country
or an organization that has particular needs and wishes to benefit from the CIM.
The regional contextual models are based on the CIM artefacts. However, a particular artefact
may be refined respecting a set of defined rules to cater for specific regional requirements.
The specific regional artefacts themselves cannot contradict the CIM artefacts on which they
are built.
From the regional contextual model, specific contextualised documents may be derived to
cater for specific information interchange functional requirements. The document contextual
models cannot contradict the regional contextual model on which they are built. They may
however introduce additional constraints to cater for the specific information requirements of
the context in which the documents are to be used.
The final modelling step applies standardised message assembly rules in order to provide an
optimised information structure for information interchange. All syntax specific electronic
documents are built from the message assembly models. This last level is not covered by this
standard.
The objective of this document is to provide the rules that ensure that each level of contextual
model refinement maintains coherence with the level on which it is based.
