CEI EN 61968-11

This part of IEC 61968 specifies the distribution extensions of
the common information model (CIM) specified in IEC 61970-301. It
defines a standard set of extensions of common information model
(CIM), which support message definitions in IEC 61968-3 to IEC
61968-9, IEC 61968-13 and IEC 61968-142. The scope of this standard
is the information model that extends the base CIM for the needs of
distribution networks, as well as for integration with
enterprise-wide information systems typically used within
electrical utilities. The information model is defined in UML which
is platform-independent and electronically processable language
that is then used to create message payload definitions in
different required formats. In this way, this standard will not be
impacted by the specification, development and/or deployment of
next generation infrastructures, either through the use of
standards or proprietary means.

For the purposes of this part of IEC 61968, the distribution CIM
(DCIM) model refers to the IEC CIM model as defined by IEC
61970-301 and this part of IEC 61968.

The common information model (CIM) is an abstract model of the
major objects in an electric utility enterprise typically involved
in utility operations. By providing a standard way of representing
power system resources as object classes and attributes, along with
their relationships, the CIM facilitates the integration of
software applications developed independently by different vendors.
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 independent of how such information is represented
internally.

IEC 61970-301 defines a core CIM for energy management system
(EMS) applications, including many classes that would be useful in
a wider variety of applications. Due to its size, the CIM classes
are grouped into logical packages, and collections of these
packages are maintained as separate International Standards. This
document extends the core CIM with packages that focus on
distribution management systems (DMS) including assets, work,
customers, load control, metering, and others. IEC 62325-3013
extends the CIM with packages that focus on market operations and
market management applications. Other CIM extensions may be
published as International Standards, each maintained by a separate
group of domain experts. Depending on a project's needs, the
integration of applications may require classes and packages from
one or more of the CIM standards.
