ENTSO-E and CIM Ø ENTSO-E needs and wants to have only one data exchange format Ø ENTSO-E organizes yearly Interoperability tests to ensure right and stable development Ø The Roadmap for the implementation of next updates of the ENTSO-E CIM Profile avoids frequent changes in the ENTSO-E CIM Profile ENTSO-E and CIM | Chavdar Ivanov | 11 May 20110 | Page 11 of 33

Current ENTSO-E CIM/XML Profile Ø Current ENTSO-E Profile is the profile tested in UCTE IOP in March 2009 in Paris. THIS IS THE PROFILE THAT MUST BE IMPLEMENTED BY ENTSO-E MEMBERS. Updates of this profile should follow the approved Roadmap Ø Proposals for changes are welcome and will be discussed within ENTSO-E, IEC and will be tested in the ENTSO-E IOP once agreed among IOP participants. Ø Current ENTSO-E CIM/XML profile is published on ENTSO-E web site (CIM part: http: //www. entsoe. eu/index. php? id=237) Ø ENTSO-E Boundary Set is available here: https: //www. entsoe. eu/resources/cim/profiles/ Ø A draft version of the 2 nd edition of the ENTSO-E CIM/XML profile was developed for the ENTSO-E interoperability test in July 2010. It is also available on the ENTSO-E web site (https: //www. entsoe. eu/fileadmin/user_upload/_library/resources/CIM/Interoperability_T ests/ENTSO-E_CIM_Model_Exchange_Profile_v 2_draft_7_IOPversion_12 July 2010. zip ) ENTSO-E and CIM | Chavdar Ivanov | 11 May 20110 | Page 12 of 33

Roadmap for future implementation of CIM Ø The aim: to structure the implementation effort. No yearly implementation. An exception could be only if a change is introduced which is critical for ENTSO-E processes Ø The implementation process is foreseen to last one year. Ø On regular basis the implementation effort is foreseen every three years, if necessary. Ø Next versions of the ENTSO-E Profile have to be approved by System Development Committee (SDC). In case of changes that affect operational data, System Operations Committee (SOC) decision is also required. Ø SDC or SDC&SOC decision ensures one year implementation period. Coming into force date is fixed and mandatory for TSOs EXAMPLE: if the updated version of the 2 nd ENTSO-E Profile for IOP 2011 is OK: - Approval by SDC and SOC - 2012 implementation year - Jan 2013 ENTSO-E switches to 2 nd edition of the profile for all exchanges.

ENTSO-E IOP Report 2010 Ø Finalized and published in mid August 2010 Ø Available on the ENTSO-E web site: https: //www. entsoe. eu/index. php? id=240 Ø Identified CIM issues were listed in the final report and submitted to IEC WG 13 for further discussion. CIM 15 resolves most of the issues ENTSO-E and CIM | Chavdar Ivanov | 11 May 20110 | Page 18 of 33

ENTSO-E exchanges in CIM – migration process to CIM Two main ENTSO-E processes are subject to CIM migration System development • Still in migration period. • First data exchanges in CIM started in February 2010. “Planning exchanges” – required for TYNDP, regional initiatives, i. e. EU 3 rd Energy Package DACF process • The goal is to complete migration stage by the end of 2011 • First test exchanges started on 8 June 2010 and finished in the end of August 2010 • Now the second stage of tests for DACF is running. TSOs are exchanging 6 files per day in CIM (one day in a week). The goal is to verify the procedures and test Communication channels. • TSOs are building their converters to CIM (operational systems to CIM) Day-Ahead Congestion Forecast process – stable exchange needed to support system operation ENTSO-E and CIM | Chavdar Ivanov | 11 May 20110 | Page 19 of 33

ENTSO-E exchanges in CIM – migration process to CIM Why after two successful IOPs (March 2009 and November 2009) the real interoperability with 1 st edition of the ENTSO-E CIM profile is still a very difficult task? ENTSO-E and CIM | Chavdar Ivanov | 11 May 20110 | Page 20 of 33

ENTSO-E exchanges in CIM – Lessons learned Ø Testing with real data is necessary. IOP test cases cannot fully represent all modelling approaches Ø More complex test models are needed. The role of CIMug and IEC in test models preparation is to be discussed Ø Some vendors introduced post IOP changes which made real interoperability not possible. Ø More strict rules on interoperability are needed to ensure that commercial products are really fully compliant with the Profile Ø Intensive communication between vendors and users is necessary to ensure right modelling and usage of right tools ØVendors should demonstrate their readiness to support ENTSO-E Profile ENTSO-E and CIM | Chavdar Ivanov | 11 May 20110 | Page 21 of 33

ENTSO-E exchanges in CIM – What ENTSO-E is doing. . . Ø To reach interoperability with 1 st edition of the ENTSO-E Profile: § TSOs are kept informed on the efforts to be done: ENTSO-E Committees meetings, various workshops § Actions have been taken to improve communication between TSO and vendors § ENTSO-E Secretariat is contacting involved vendors on daily basis Ø To ensure future interoperability and improve business process: § ENTSO-E IOP 2011 will test both 1 st and 2 nd edition of the profile § Strict validation of the naming convention will be done during IOP 2011 § Vendors will be asked to export test models that they already have and demonstrate interoperability § The 2 nd edition of the profile is fully based on the 452, 456, 453, 552, etc. standards. Exchange flexibilities are improved. Open issues are clarified § ENTSO-E will implement a Network Modelling Database ENTSO-E and CIM | Chavdar Ivanov | 11 May 20110 | Page 22 of 33

Overall concept of Power System Database Network Modelling Database (NMD) as a part of the Power System Database concept ENTSO-E and CIM | Chavdar Ivanov | 11 May 20110 | Page 23 of 33

Network Modelling Database – time schedule, objectives ü ü Preparation work and ENTSO-E decisions in 2010 EU tender started in Dec 2010; offers assessment is ongoing Contract expected in July 2011; NMD fully operational Jan 2012. Objectives: ü To adapt ENTSO-E business process to an automatic CIM based data exchange ü To have a system that supports the official ENTSO-E CIM profile and supports development of next editions of the profile. In Jan 2012 NMD should support 1 st and the 2 nd (July 2011) editions of the profile ü Provide automatic model assembling functionalities based on the ENTSO-E CIM profile, i. e. MAS, boundary sets. ü Allow users to maintain TSO, regional, pan-European models; store scenarios; import/export full, partial, differential files ü Allow specific queries, etc. ENTSO-E and CIM | Chavdar Ivanov | 11 May 20110 | Page 24 of 33

Common CIM Tools used by TSOs Ø CIMdesk Ø Validation, visualization and editing tool developed by Power.
