  1. The Common Information Model (CIM) accepted/implemented Globally- for operations, planning, markets, and throughout the Enterprise David Becker, EPRI Presented at the “ 2005 EMS Users Group Meeting” Providence, R.I. September 13, 2005

  2. History of the Common Information Model (CIM) • Late 1980’s-Early 90’s- Informal meetings of Industry focused on “How to achieve “open system design” • 1993-Formation of EPRI led CCAPI Task Force: “ One vendor did not have all solutions for a customer. Need for integration” • Initial Goals of CCAPI: • Provide common information model to facilitate information exchange • Enable use of plug in applications • Protect application investment • Framework for integration of legacy systems

  3. The Common Information Model Defines Power System Resources, Attributes and Relationships Company Generator Control Area Operates Controls Supplies Energy for Connects to Busbar Provides Transmission for Load Connects to Connects to AC Line Company Owns

  5. Important Milestones • 9/1996: CIM initially submitted to IEC; CIM 10 final version accepted for standard in 2001. First major CIM Installation 1998 • Component technology emerged in late 1990’s . CCAPI calls them Component Interface Specs (CIS). Key to facilitating integration in a distributed environment • Generic Interface Design (GID) initial design submitted to IEC 12/2001 after 2 yrs technical debate and design • SW developers create components w/o concern for underlying infrastructure • GID guides standard API for an application to exchange/access data

  13. Scope of Markets Project Inter-ISO/RTO Messaging Intra-ISO/RTO Messaging Generators RTO A MIS Settlement RTO A ISO B Marketers SCUC SCED ISO D RTO C Loads CIM extensions in scope for CME XML information exchange model and terms database – message standards to be developed as part of RTO/ISO Data Initiative Market, Load, Generation Participants CIM extension and information exchange model – Other Initiatives and/or Future Phase(s)

  14. CIM XML Interoperability Tests • EPRI has sponsored six interoperability tests based on the CIM XML standards: • Six interoperability tests successfully completed exchanging real-world large scale models (12,000 bus) and several sample models (40 to 100 bus) • December 2000: Orlando, Florida • April 2001: Las Vegas, Nevada • September 2001: Monterey, California • July 2002: San Francisco, California • November 2003: Cleveland, Ohio • July 2004: Folsom,California • Validated the use and acceptance of this standard by suppliers who provide products to the electric utility industry • Test reports available from EPRI

  15. INTEROPERABILITY TESTS Interoperability Tests very important IOP #7 Sept 27,28,29,30 2005 Vendors: ABB,Areva,EDF, Siemens PTI,Siemens,SISCO

  16. CIM Status and Access Information • Survey ( 2 years old) shows over 47 CIM installations in US and over 55 applications delivered. New survey to be done in 2005.( How do you count rabbits?) USA started 2+ years ahead of other countries • Globally accepted now. Known implementations in process or done in Belgium, Brazil, China, France, Ireland, Jordan, Russia, Slovenia, South Africa, Spain, others(?)
