UCTE Viewpoint towards CIM project report Chavdar Ivanov

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

Why discussions about a new common format? Needs (UCTE, regional, bilateral) Constraints of the current format Operational Even if sufficient for operational processes -DACF in many cases, the models are very often an -Reference cases input to system studies processes -Snapshots, etc System studies -Load flow: limitations in modelling of -Planning (TYNDS) detailed generation, three-winding -Various studies (system extension, wind transformers, shunts, etc. integration, 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 page 2

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. Ah. G UCTE format was established. May 2008: UCTE SC approved – the cooperation of Ah. G “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 TC 57. UCTE CIM TF is established during CIMug meeting in Vasteras (June 2008) page 3

Project timeline (1) Before 06/2008 Decisions on the CIM/XML - based format direction 25/Sep/2008 Ah. G UCTE format submitted a proposal for CIM extensions to IEC 20/Nov/2008 Common meeting Ah. G – UCTE CIM TF Transformers are so complex… Do we need them? page 4 11/Dec/2008 First teleconference for UCTE IOP will be in March 2009. Is it feasible? 23/Dec/2008 First version of the profile When we have the final profile?

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

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

Tools - Developed by Power. Info 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 pe rab Int ero T bu SOs sin es s Interoperability -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 page 7 ility b era TSOs TE s UC ide ov pr Migration converter UCTE DEF/CIM -Contacts with vendors to obtain CIM upgrade; - Development of CIM based modules, if necessary - etc. p ero Int ility UCTE provides Visualization and editing tool TSO’s tools

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) page 8

Thank you All UCTE TSOs that contributed to UCTE Profile development UCTE IOP participants (test directors, vendors and witnesses) IEC, EPRI, CIMug page 9
