Energy Management System Application Program Interface (EMS-API) - Part 552: CIMXML Model Exchange Format

IEC 61970-552:2013 specifies a Component Interface Specification (CIS) for Energy Management Systems Application Program Interfaces. This part specifies the format and rules for exchanging modelling information based upon the CIM. It uses the CIM RDF Schema presented in IEC 61970-501 as the meta-model framework for constructing XML documents of power system modelling information. The style of these documents is called CIMXML format. This standard supports a mechanism for software from independent suppliers to produce and consume CIM described modelling information based on a common format.

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.

International Standard IEC 61970-552 has been prepared by IEC technical committee 57,

Power systems management and associated information exchange.

This second edition cancels and replaces the first edition published in 2013. This edition

constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous

edition:

a) New Clause 4 that defines the versioning of CIMXML format described in this document.

b) Subclause 5.1, the statement on work flow support is removed.

INTRODUCTION

This part of IEC 61970 is part of the series of standards that define an Application Program

Interface (API) for an Energy Management System (EMS).

IEC 61970-301 specifies a Common Information Model (CIM): a logical view of the physical

aspects of an electric utility operations. The CIM is described using the Unified Modelling

Language (UML), a language used to specify, visualize, and document systems in an object-

oriented manner. UML is an analysis and design language; it is not a programming language.

In order for software programs to use the CIM, it must be transformed into a schema form that

supports a programmable interface.

IEC 61970-501 describes the translation of the CIM in UML form into a machine readable

format as expressed in the Extensible Markup Language (XML) representation of that schema

using the Resource Description Framework (RDF) Schema specification language.

This part of IEC 61970 specifies how the CIM RDF schema specified in IEC 61970-501 is

used to exchange power system models using XML (referred to as CIMXML) defined in the

61970-45x series of profile standards, such as the CIM Transmission Network Model

Exchange Profile described in IEC 61970-452.

ENERGY MANAGEMENT SYSTEM APPLICATION
PROGRAM INTERFACE (EMS-API) –
Part 552: CIMXML Model exchange format
1 Scope

This part of IEC 61970 specifies the format and rules for exchanging modelling information

based upon the CIM. It uses the CIM RDF Schema presented in IEC 61970-501 as the meta-

model framework for constructing XML documents of power system modelling information.

The style of these documents is called CIMXML format.

Model exchange by file transfer serves many useful purposes. Profile documents such as

IEC 61970-452 and other profiles in the 61970-45x series of standards explain the

requirements and use cases that set the context for this work. Though the format can be used

for general CIM-based information exchange, specific profiles (or subsets) of the CIM are

identified in order to address particular exchange requirements. The initial requirement driving

the solidification of this specification is the exchange of transmission network modelling

information for power system security coordination.

This part of IEC 61970 supports a mechanism for software from independent suppliers to

produce and consume CIM described modelling information based on a common format. The

proposed solution:
• is both machine readable and human readable, although primarily intended for
programmatic access,

• can be accessed using any tool that supports the Document Object Model (DOM) and

other standard XML application program interfaces,
• is self-describing,
• takes advantage of current World Wide Web Consortium (W3C) recommendations.

Real-World Object

objects that belong to the real world problem domain as distinguished from interface objects

and controller objects within the implementation

Note 1 to entry: The real-world objects for the EMS domain are defined as classes in IEC 61970-301 Common

Information Model.

Note 2 to entry: Classes and objects model what is in a power system that needs to be represented in a common

way to EMS applications. A class is a description of an object found in the real world, such as a PowerTransformer,

GeneratingUnit, or Load that needs to be represented as part of the overall power system model in an EMS. Other

types of objects include things such as schedules and measurements that EMS applications also need to process,

analyze, and store. Such objects need a common representation to achieve the purposes of the EMS-API standard

for plug-compatibility and interoperability. A particular object in a power system with a unique identity is modeled

as an instance of the class to which it belongs.

5 Model exchange
5.1 General

Model exchange typically involves the exchange of a collection of documents, each of which

contains instance data, referred to as a model, and a header. The structure and semantics of

each model as well as the header are described by a profile, which is not included in the

exchanged data. The overall exchange is governed by a collection of profiles in a Profile

Document.
A CIMXML document shall consists of a header and a model section.

A header section describes the content of the model section contained in a document e.g. the

date the model was created, description etc. The header may also identify other models and

their relationship to the present model. Such information is important when the models are

part of a work flow where, for example, the models have relations to each other, e.g. a model

succeeds and/or depends on another.
5.2 Rules for CIMXML documents and headers
A CIMXML document is described by a single header. Multiple headers in a CIMXML
document are not allowed.
