1 “ Future of Oasis Conference”
International Standards Common Information Model (CIM) CIM for Market Extensions (CME) and Oasis David Becker, EPRI Presented at the NERC/NAESB “ Future of Oasis Conference” Washington DC 3/29/2005

2 Outline for CIM/Oasis II
What is CIM? Why are Standards important? For Oasis? CIM Extensions for Market Operations (CME)

3 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

4 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 AC Line Connects to Company Owns

5 Changing Design of CCAPI in 90”s
Design focus changed from EMS control computer systems to Enterprise data exchange Expand to use new applications with “plug and play” USA technical team expanded with all world experts Standards Org (IEC) WG’s of control centers, substations, distribution ALL adopt CIM as base

6 Important Milestones 9/1996: CIM initially submitted to IEC; CIM 10 final version accepted for standard in 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

14 CIM today CIM 10 is ready for use. Has Widespread acceptance
CIM for Asset Mgmt also robust and ready for your use Deployment of CIM Projects now ongoing worldwide Integration of CCAPI into Substations Integration of CIM for Market Extensions

15 Why International Standards
Global world. Many vendors international Vendors willing to build products to STANDARDS Allows multiple designs to compete New applications can be installed Migration path more robust & flexible Lower vendor costs to produce and sell

17 Initiative of CIM for Market Extensions (CME) Project
FERC requested EPRI to extend the CIM architecture to support the SMD and facilitate markets EPRI initiated CIM for Market Extensions (CME) project with ISO’s/RTO’s ,vendors Made up of utility and industry organizations to support this initiative Managed by Xtensible Solutions for EPRI Focus on the Day-Ahead and Real-Time Market Processes to define extensions needed for the CIM data model to support these processes Goal of CME Standardize information format and application interfaces to make the North American wholesale electricity market run efficiently, reduce seams issues and save substantial costs in the development of applications for each RTO Will allow RTOs to buy best-of-breed applications and communicate with Independent Transmission Organizations (ITOs) or other ISOs and RTOs in a standard information format Will allow marketers, Load Serving Entities (LSE), and Generator Serving Entities (GSE) to access information and bid into the RTO’s preferred format

18 Scope of CME Project RTO A Inter-ISO/RTO Messaging
Intra-ISO/RTO Messaging Generators RTO A RTO A ISO B MIS Settlement Marketers ISO D RTO C SCUC SCED 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)

19 CME Phase 1 Deliverables
EPRI Technical Report: “CIM Extensions to Support Market Operations Phase 1: Day Ahead and Real Time Scheduling Applications” (TR ) CIM representation of data requirements in table format with mapping to existing applications Extended CIM UML model to support the SCUC/ED/LMP data requirements New Market Operations package Updates to existing CIM Packages Reuse of existing IEC and Packages Created XML Schema for the Input/Output data Basis for the message standards defined for the SCUC application by the ITC Standards Collaborative

20 Phase 1 CIM UML Extensions
New CIM Package created for Market Operations Bid Resource RTO Security Constraints Clearing Results Updates to existing CIM Packages Energy Scheduling Financial Reuse of existing IEC and Packages 61970 – Core, Generation/Production, Measurements, others Core2/Top Level and Activity Record

21 CME Phase 2 Deliverables
EPRI Technical Report: “CIM Extensions to Support Market Operations Phase 2: Day Ahead and Real Time Scheduling Applications” (TR ) Extended CIM UML model to support the SCUC/ED/LMP data requirements Network Analysis applications (e.g., State Estimator, Security Analysis, OPF, etc.) Ex-Post LMP Financial Transmission Rights (i.e., Congestion Reservation Rights) Facilitated Checkout (FCO) Updates to the CIM UML Rose model for Market Operations

22 Benefits Derived From CME Project
Basis for defining standard messages for exchange of market operations data in support of SMD Provides semantic layer for ensuring consistency in meaning and use of information exchanged to support market operations and reliability Facilitates implementation of market business processes Provides architectural layer to map business terms to data definitions used in message payloads Basis for new RTO/ISO SMD development efforts Ex: CAISO is using CME extensions on Market Redesign project as starting point for developing message payloads for information exchange between systems and applications Submitted to IEC for consideration as international standard Could lead to adoption by European Transmission Operators

23 CME Phase 3 Prioritized Activities
High Priority Standard message definitions SCED and Ex-Ante LMP message standards FCO – revisit other ISO/RTO requirements Network Analysis and Ex-Post LMP Financial Transmission Rights Market participant interaction - Upload electronic bids to RTO/ISO and download results. Market participant interaction - Settlement data exchange and True-Ups Plan and conduct a Workshop or Webinar on CME results for interested users (after Phase 2 message definition complete) High to Medium Priority Control Area seams-related data exchange Applications include ramp data, Total Transmission Capacity (TTC), ATC, Available Flowgate Capacity (AFC), etc. that are exchanged among control areas

24 CME Phase 3 Prioritized Activities
Medium Priority Network model maintenance component (i.e., complete model transfers, incremental model updates, and partial model transfers) Intelligent Alarming Sharing relaxant relevant alarms with neighbors electronically Visualization Information exchange to enable display of Market and Reliability data in a graphical form that will assist in decision making Low Priority Market monitoring information Plan for and conduct an Interoperability test in 2006 for CME standard messages developed on the extended CIM Market participant interaction – Outage reporting Develop a User Guide on how to use the CIM for market operations messaging.

25 CIM XML Interoperability Tests
