Model Exchange TF Vasteras, June 12, 2008 Jay Britton jay.britton@areva-td.com

Agenda Primary Topic: UCTE Model Exchange Project Chavdar Ivanov, Erik Wolfs Review requirements Develop action plan for working with CIM Make sure that UCTE extensions are consistent with requirements for other interconnections Nordel, for example

UCTE TSO Upload/Download CIM Interface Proposal Initialization Files (1 per day or as changed) 452 CIM/XML model exchange – full model authority set Include physical connectivity, electrical characteristics Omit load, generation, regulation targets, etc. Case Specification Files (n cases per day) 452 Incremental model update Header specifies time of day and case sequence number Body of case is usually null because configuration often doesn’t change 45x CIM/XML Topology result Buses Equipment status (in or out of service) 45y CIM/XML scheduled value exchange Load at consumers Generation at generators Regulation targets 45z CIM/XML solution value exchange? Solved voltages Solved taps Solved generation X-node Files (exchanged when changed) One set for each pair of TSOs that have ties All files governed by 552.

Discussion Items New UCTE model Transformers Nodes Separates units and loads and shunts Separates equivalents Transformers Should we move to 2-w object separate from 3-w object? General review of model adequacy is needed. Nodes Retaining consistent bus names Nodes are TopologyNode in CIM – output of topology processing Load, gen, limits, etc. assembled for topologynodes.

Action Plan 16/6 – Discuss necessary new interfaces in WG13 and provide scope statements to guide UCTE development. 11/7 – UCTE will prepare requirements document. 18/9 – First draft of interface profiles (including CIM extensions) will be produced for each interface by the joint working group: Erik Wolfs (Elia) Chavdar Ivanov (UCTE) Jay Britton (AREVA) Lars-Ola Osterlund (ABB) Patrick Panciatici (RTE) Michael Barlow (Siemens-PTI) Eric Lambert (EDF R&D) Maurice Adriaensen (KEMA) Ernst Wierenga (Tennet) Discussion and iterations of documents. 3/10 – WG13 Seoul Meeting will review and comment on current draft profiles. Further revision… 1/11 – UCTE to CIM converter produced by EDF to produce test case. 31/12 – Target date for prototype of CIM exchange.
