Energy Management System Application Program Interface (EMS-API) - Part 452: CIM static transmission network model profiles

This part of IEC 61970 is a member of the IEC 61970-450 to -499 series that, taken as a
whole, defines at an abstract level the content and exchange mechanisms used for data
transmitted between control centers and/or control center components.
The purpose of this document is to rigorously define the subset of classes, class attributes,
and roles from the CIM necessary to execute state estimation and power flow applications.
The North American Electric Reliability Council (NERC) Data Exchange Working Group
(DEWG) Common Power System Modeling group (CPSM) produced the original data
requirements, which are shown in Annex C. These requirements are based on prior industry
practices for exchanging power system model data for use primarily in planning studies.
However, the list of required data has been extended to facilitate a model exchange that
includes parameters common to breaker-oriented applications. Where necessary this
document establishes conventions, shown in Clause 5, with which an XML data file must
comply in order to be considered valid for exchange of models.
This document is intended for two distinct audiences, data producers and data recipients, and
may be read from two perspectives.
From the standpoint of model export software used by a data producer, the document
describes a minimum subset of CIM classes, attributes, and associations which must be
present in an XML formatted data file for model exchange. This standard does not dictate how
the network is modelled, however. It only dictates what classes, attributes, and associations
are to be used to describe the source model as it exists. All classes, attributes, and
associations not explicitly labeled as recommended or conditionally required should be
considered required with the following caveat. Consider, as an example, the situation in which
an exporter produces an XML data file describing a small section of the exporter’s network
that happens to contain no breakers. The resulting XML data file should, therefore, not
contain an instance of the Breaker class. On the other hand, if the section of the exporter’s
network does contain breakers, the resulting data file should contain instances of the Breaker
class that include, at a minimum, the attributes and roles described herein for Breakers.
Furthermore, it should be noted that an exporter may, at his or her discretion, produce an
XML data file containing additional class data described by the CIM RDF Schema but not
required by this document provided these data adhere to the conventions established in
Clause 5.
From the standpoint of the model import used by a data recipient, the document describes a
subset of the CIM that importing software must be able to interpret in order to import exported
models. As mentioned above, data providers are free to exceed the minimum requirements
described herein as long as their resulting data files are compliant with the CIM RDF Schema
and the conventions established in Clause 5. The document, therefore, describes additional
classes and class data that, although not required, exporters will, in all likelihood, choose to
include in their data files. The additional classes and data are labeled as recommended or as
not required to distinguish them from their required counterparts. Please note, however, that
data importers could potentially receive data containing instances of any and all classes
described by the CIM RDF Schema

Part 452: CIM model exchange specification

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 f
