CEI EN 62325-450

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.
