1. UCTE Viewpoint towards CIM – project report Chavdar Ivanov, Ph.D. UCTE Secretariat, Convenor of AhG UCTE format CIM User Group meeting, 12-15th May 2009, Genval, Belgium

2. page 2 Why discussions about a new common format? Needs (UCTE, regional, bilateral)Constraints of the current format Operational -DACF -Reference cases -Snapshots, etc Even if sufficient for operational processes in many cases, the models are very often an input to system studies processes System studies -Planning (TYNDS) -Various studies (system extension, wind integration, etc) -Load flow: limitations in modelling of detailed generation, three-winding transformers, shunts, etc. -Dynamics: not included - A lot of software tools are being used among the UCTE TSOs - The idea about a mutual acceptance of another existing commercial format as a standard for data exchanges is not supported

3. page 3 Seite Aufzählung From ASCII to CIM..... (Important decisions) November 2007: UCTE agreed to launch an initiative for development of new UCTE XML based data exchange format that will considered as a standard for exchange of load flow and dynamic data and allows performing of all kind of analyses as follows: steady state, unbalanced short circuit and dynamic analyses. AhG UCTE format was established. May 2008: UCTE SC approved –the cooperation of AhG “UCTE format” with international organizations aiming at inclusion of UCTE needs into international standard –the UCTE participation in EPRI project (CIM for Dynamics) Summer 2008: UCTE joins the EPRI Project and creates a liaison with IEC TC57. UCTE CIM TF is established during CIMug meeting in Vasteras (June 2008)

IOP will be in March 2009. Is it feasible? When we have the final profile?

5. page 5 Project timeline (2) IOP preparation Jan-Mar/2009 UCTE IOP 23-27/03/2009 IOP Training. Decisions on UCTE Profile 20/01/2009 We will exchange 3 files instead of one and test the new IEC approach. Sounds good! Work, work, work. The profile is improving. I cannot hear any complains Congratulations! We did a good job. We have some issues to solve. UCTE wants fast implementation… UCTE Migration policy approved 22/Jan/2009

6. page 6 Project timeline (3) UCTE Visualization and editing tool 15/July/2009 End of maintenance of UCTE DEF/CIM converter usage Dec/2010 UCTE Profile submitted to IEC Start exchanges using CIM. Priority for Planning, System studies Sep/2009 May-Sep/2009 Internal UCTE tests using CIM. UCTE DEF/CIM converter IEC Standards 2010 Involvement in CIM for Dynamics project 13-16/July/2009 IOP CIM for Dynamics 11/May/2009 => 2008/2009 CIM for Dynamics Implementation stage – Migration policy

7. page 7 Tools Interoperability TSOs Visualization and editing tool Migration converter UCTE DEF/CIM TSO’s tools Interoperability UCTE provides UCTE provides TSOs business -Contacts with vendors to obtain CIM upgrade; - Development of CIM based modules, if necessary - etc. - Developed by PowerInfo LLC - to provide users with possibilities for direct editing of CIM data exchange format and graphical visualization - it is not related to the migration. It will be used and maintained as long as CIM /XML format is used -Developed by EDF R&D -to convert from UCTE CIM to UCTE DEF (current version: version 02) and vice versa - to be used during the migration stage

8. page 8 Seite Aufzählung UCTE view on CIM development and maintenance It is necessary to maintain a stable CIM version and clear roadmap for CIM development. –Establishment of clearly defined external consultation process before approval of next release by IEC. –A reference file for every version or implementation of version control system from CIM sharepoint or EA. Regular reports/announcements on ongoing projects (issued by CIMug or IEC)
