Technical committeeTypeAcronymIEC 62325-301CommitteePublished year2018Description
IEC 62325-301:2018 specifies the common information model (CIM) for energy market communications. The CIM facilitates integration by defining a common language (i.e. semantics) 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. The object classes represented in the CIM are abstract in nature and may be used in a wide variety of applications. The use of the CIM goes far beyond its application in a market management system. This new edition of IEC 62325-301 contains support for demand-side communication within a wholesale market. The IEC 62325-301 additions include support for demand-side resource registration and enrollment of a market participating resource as well as support for deployment and performance evaluation of demand side resources. A new package has been included in this edition of IEC 62325-301 to support environmental (weather) data.

IEC 61970-552:2016 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 new edition includes the following significant technical changes with respect to the previous edition:
- new clause that defines the versioning of CIMXML format;
- addition of a statement about mandatory header;
- introduction of the new urn:uuid form and discussion of the backwards compatibility. -
Technical committeeTypeAcronymIEC 61970-501CommitteePublished year2006Description
Specifies the format and rules for producing a machine readable form of the Common Information Model (CIM) as specified in the IEC 61970-301 standard. Describes a CIM vocabulary to support the data access facility and associated CIM semantics.
This publication is of core relevance for Smart Grid.

IEC 61970-456:2018 rigorously defines the subset of classes, class attributes, and roles from the CIM necessary to describe the result of state estimation, power flow and other similar applications that produce a steady-state solution of a power network, under a set of use cases which are included informatively in this standard. This document is intended for two distinct audiences, data producers and data recipients, and may be read from those two perspectives.
This new edition includes the following significant technical changes with respect to the previous edition:
- Addition of the Steady State Hypothesis (SSH) profile.
- Better description of the relation between different profiles and alignment with the current nomenclature used with profiles, e.g. "data set" and "network part".
- Extension of the description of the use cases. -

IEC 61970-453:2014+A1:2018 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 centre components. Included in this part of IEC 61970 are the general use cases for exchange of diagram layout data, and guidelines for linking the layout definitions with CIM data. Guidelines for management of schematic definitions through multiple revisions are also included. This new edition includes the following significant technical change with respect to the previous edition: The SVG elements and its data model have been replaced by the Diagram Layout Package, which is now an integral part of the IEC 61970-301 (CIM) model.
This consolidated version consists of the second edition (2014) and its amendment 1 (2018). Therefore, no need to order amendment in addition to this publication. -

IEC 61970-452 IEC 61970-452:2017 defines the subset of classes, class attributes, and roles from the CIM necessary to execute state estimation and power flow applications. This standard 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 new edition includes the following significant technical changes with respect to the previous edition: the Equipment profile has been split into three separate profiles, CoreEquipment, Operation and ShortCircuit; the HVDC model has been replaced with the new model defined in Edition 6 of 61970‑301. the specific profiles (or subsets) of the CIM for exchange of static power system data between utilities, security coordinators and other entities participating in a interconnected power system.

This standard specifies the interfacesSpecifies the framework for the specification of Component Interface Specifications (CIS) for Energy Management System Application Program Interfaces. A CIS specifies the interfaces that a component (or application) should implement to be able to exchange information with other components (or applications) and/or to access publicly available data in a standard way.
This publication is of core relevance for Smart Grid. that a component (or application) shall implement to be able to exchange information with other components (or applications) or (and) to access publicly available data in a standard way.

IEC 61970-301:2020 (E) lays down the common information model (CIM), which is an abstract model that represents all 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 network applications developed independently by different vendors, between entire systems running network applications developed independently, or between a system running network applications and other systems concerned with different aspects of power system operations, such as generation or distribution management. SCADA is modeled to the extent necessary to support power system simulation and inter-control centre communication. The CIM facilitates integration by defining a common language (i.e. semantics) 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.
This edition reflects the model content version ‘IEC61970CIM17v38’, dated ‘2020-01-21’, and includes the following significant technical changes with respect to the previous edition:
a) Added Feeder modelling;
b) Added ICCP configuration modelling;
c) Correction of issues found in interoperability testing or use of the standard;
d) Improved documentation;
e) Updated Annex A with custom extensions;
f) Added Annex B Examples of PST transformer modelling;
g) Added Annex C HVDC use cases.Technology -
