CIM Conformity and Interoperability

CGMES Conformity

The interoperability of the applications used by TSOs for operational and system development exchanges is crucial and ENTSO-E has the objective to ensure the interoperability via compliance of those applications with the Common Grid Model Exchange Specification (CGMES) requirements (now IEC Technical Specifications 61970-600-1: 2017 and 61970-600-2: 2017). Thus ENTSO-E approved the CGMES Conformity Assessment Framework which establishes services:

• to facilitate the elaboration of the IEC specifications TS 61970-600-1 and 61970-600-2,

• the implementation of the European network codes, and

• the elaboration of the system development studies, specific power system analysis software and IT systems (both hereafter referred to as Applications) that are used to ensure smooth data exchanges between TSOs.

The current design of the CGMES Conformity Assessment Scheme v2.0 allows assessment of the applications only on certain CGMES functionalities that are supported by the assessed Application, i.e. a theoretical approach is used when initially defining the conformity scheme. Hence declarations of conformity and attestations of conformity shall not be used as a confirmation that an application is fully covering requirements on a specific business process.

It is planned to further develop the CGMES Conformity Scheme to cover relevant procedures and test use cases, so as to be able to test and declare the applications used by TSOs as conform to the requirements of the business processes such as DACF and other operational planning exchanges as well as long term planning data exchanges.

Conformity Assessment Scheme

Conformity assessment scheme v2.0 defines the complete set of documentation (related version of the IEC specifications TS 61970-600-1 and 61970-600-2, test configurations, test procedures, etc.) valid for this version.

Suppliers of Applications supporting IEC specifications TS 61970-600-1 and 61970-600-2 are requested to use the available documentation and test configuration, and submit their Declaration of Conformity at earliest convenience.

Every stakeholder/supplier is asked to report any further version of their application for which an Attestation has been already released. In case they want to have the new application version conform without running again the procedure they can declare with supporting document that the new version still supports previous conformity level achieved.

Disclaimer:

The test configurations (models), documents and application profiles are owned by ENTSO-E and are provided by ENTSO-E “as it is”. To the fullest extent permitted by law, ENTSO-E shall not be liable for any damages of any kind arising out of the use of the test configurations (models), documents and application profiles (including any of their subsequent modifications).

ENTSO-E neither warrants, nor represents that the use of the test configurations (models), documents and application profiles will not infringe the rights of third parties. Any use of the test configurations (models), documents and application profiles shall include a reference to ENTSO-E. ENTSO-E web site is the only official source of information related to these test configurations (models), documents and application profiles.

Conformity Registry

The current design of the CGMES Conformity Assessment Scheme allows assessment of the applications only on certain CGMES functionalities that are supported by the assessed application, i.e. a theoretical approach is used when initially defining the conformity scheme. Hence declarations of conformity and attestations of conformity shall not be used as a confirmation that an application is fully covering requirements on a specific business process.

It is planned to further develop the CGMES Conformity Scheme to cover relevant procedures and test use cases, so as to be able to test and declare the applications used by TSOs as conform to the requirements of the business processes such as DACF and other operational planning exchanges as well as long term planning data exchanges.

​​​The Conformity Assessment Framework and related operational procedures require that the Conformity Registry is publicly available​. The table below contains information on:

• Supplier’s Name: The name of the Supplier.

• Contact Info: The Supplier’s contact person.

• Application’s Name and Version: The name and version of the Application. The objective is to be able to identify an exact version of a Supplier’s application.

• CGMES Conformity Version: The reference to the version of the CGMES against which the Application was assessed.

• Scheme Version: The version of the Conformity Assessment Scheme that has been used when assessing the Application.

• Declaration of Conformity: The pdf file provided by the Supplier declaring its conformity – with an indication of the date by when the Supplier declares its Application to be conformed to the CGMES and the date by when the Supplier declares its Application ceases to be conformed to the CGMES.

• Attestation of Conformity: The pdf file provided by the Assessment Body declaring its attestation – with an indication of the date by when the Assessment Body declares the application is conform to the CGMES and the date by when the application is no longer CGMES conform.

CIM Interoperability tests (IOP)

Interoperability tests, in general, are tests to support efforts to have interoperability among applications. Interoperability tests are done at various stages: when developing the specification using draft specification and prototype tools; during conformity assessment so called Factory Acceptance Test (FAT) testing using final specification and applications exchanging test data; and during Site Acceptance Test (SAT) testing where the tools are challenged with real datasets.

ENTSO-E is improving the CGMES continuously based on feedback from system operation and system development business processes and to ensure that additional requirements defined in the network codes are well covered. This page covers interoperability tests that are regularly organized to validate draft standards/technical specifications before they become published and ensure that the vendors can develop support before the ‘ultimate’ standard is published.

Issues recorded during this testing and proposed resolutions are included in the IOP report, along with some guidelines on how to implement the CIM standards within the TSO/utility enterprise. Details on the test procedures and discussed topics are included in the report appendices. All this information is an input for further development and finalization of CGMES version in ENTSO-E, finalization of standards in IEC, finalization of a version of CGMES conformity assessment scheme.

ESMP Interoperability tests (IOP)

Since July 2012, ENTSO-E has been conducting interoperability tests on the IEC CIM 62325 series of standards for the electricity market, where European Transmission System Operators (TSOs), Transmission Capacity Allocators (TCAs), Transmission Capacity Auction Offices and Market Management System (MMS) software providers are invited to participate.

The IOP tests aim to demonstrate that the IEC 62325-451-‘X’ series of standards, each satisfies the information requirements for the corresponding business processes in the European style market profile, and that the IEC 62325-301 (CIM) and IEC 62325-351 (European style market profile) are consistent.

The results of all the IOP tests conducted have been in line with expectations and are summarised in the corresponding final IOP reports, which have been approved by ENTSO-E’s Market Committee, and conclude that:

• The work carried out on the IEC 62325-301, “CIM extensions for market”, IEC 62325-351, “CIM European market model exchange profile” and IEC 62325-451-1, 2 and 3 standards, “Acknowledgement business process and contextual model for CIM European market”, “Scheduling business process and contextual model for European market”, and “Transmission capacity allocation business process (explicit or implicit auction) and contextual models for European market”, is in line with the business requirements;
• There are no major deficiencies in the standards;
• The standards include all the capabilities needed to support the exchanges already implemented within ENTSO-E.

To facilitate the migration to IEC CIM 62325 series, and the transformation of ENTSO-E’s xml files into IEC CIM 62325 ones and vice-versa.
