CIM Standards Status Testing and Collaboration Randy Rhodes

CIM Standards: Status, Testing, and Collaboration Randy Rhodes CIMug Utility Co-Chair EMS Users Conference September 15, 2009

CIM Standards • • • What is the CIM? Who is UCAIug and IEC? How is the CIM Used? How is the Model Developed? How Can Utilities Get Involved?

• • What is the CIM? A Unified Modeling Language (UML) based information model representing realworld objects and information entities exchanged within the value chain of the electric power industry – Maintained by IEC in the Sparx Enterprise Architect modeling tool Enable integration of applications/systems – Provides a common model behind all messages exchanged between systems – Basis for defining information exchange models Enable data access in a standard way – Common language to navigate and access complex data structures in any database • Provides a hierarchical view of data for browsing and access with no knowledge of actual logical schema – Inspiration for logical data schemas (e. g. , for an operational data store) Not tied to a particular application’s view of the world – But permits same model to be used by all applications to facilitate information sharing between applications

Benefits of Using CIM • • • Data model driven solutions leads to interoperability Provides common semantics for information exchange between heterogeneous systems Provides for automatic generation of message payloads in XML – Ensures common language for all messages defined – Avoids proprietary message formats from vendors – Eliminates work of creating XML tags for each message – Alternative to EDI or CSV file formats Uses industry standard modeling notation Click to Learn More – UML, XML about CIM Permits software tool usage for: • CIMug Site (www. cimug. org) – Defining and maintaining data models • Recent Presentations • Single point of maintenance for changes • Ask for Help – Documenting data models • FAQs – Automatic generation of information payloads Open a guest account!

CIM Documentation • CIM documentation is split into 5 major categories – 61970 -1: Guidelines and General Requirements • Describes the component based reference model • Includes general capabilities for integration infrastructure – 61970 -2: Glossary – 61970 -3 xx: Common Information Model • 301: Paper copy of the model – Published yearly by IEC – Latest version: CIM 13, v 19 – Electronic copy on CIMug web site – 61970 -4 xx: Component Interface Specifications (CIS) • Interfaces that a component should implement to be able to exchange information with other components • Information content (messages) that a component exchanges • 2 major divisions – 401 – 449: Generic service specifications – 450 – 499: Specific information exchange requirements – 61970 -5 xx: CIS Technology Mappings • RDF Schema, Web Services Profile, OWL Schema, XML format, Graphics Exchange

Who is IEC and UCAIug? • The International Electrotechnical Commission (www. iec. ch) is “the world's leading organization that prepares and publishes International Standards for all electrical, electronic and related technologies” • UCA International Users Group (www. ucaiug. org), a non-profit dedicated to promoting standards, has Liaison status with IEC – CIM Users Group (www. cimug. org) is one of several groups within UCAIug – UCAIug and CIMug members can review draft standards – Non-Members can not access draft standards

How is CIM Used? (2008 Survey Results)

CIM Use by Business Function

Total Number of Applications Affected by CIM = 127

How is the Model Developed? CIM for Dynamics CIM for Planning CIM Issues UCTE ERCOT Interoperability Tests CIM for Distribution UML Model and Profile Changes IEC Approval CIM Release 13

Industry Activity 2008 (Actual) UCTE Interoperability Test Dynamics Interoperability Test Finalize UML and Produce CIM 14 Release CPSM Interoperability Test Resolve Issues from Interoperability Tests Jan 2009 Feb Mar Apr May Jun Jul Aug Sep 2009 (Planned) Oct Nov Dec 2010

New Industry Activity • CIM for Planning Interop – Washington, D. C. - November 12 -13, 2008 – Participants: • Areva (source model only) • GE, Siemens-PTI • CIMSpy – results validation – Scope • Import & export planning model files • Solving power flows • Did not include dynamic models – Results: Passed all tests

New Industry Activity • UCTE Interop – UCTE represents operators in 24 European countries – Paris - March 23 -27, 2009 – Ten products from eight vendors • • Areva T&D CESI-BU Electric Power Systems Dig. Silent Electricity of France EPS Software RTE/Tractebel Siemens PTI SISCO – Scope • Three test models (10, 21, and 9200 nodes) • 40 participants including witnesses from 10 TSOs • Model import/export with CIM XML-RFD files • Solving power flows • Exchanging solved cases – A Significant Success

CIM Site Activity – Prior Year 14, 252 visits came from 1, 367 cities in 97 countries across 19 subcontinents

CIM Site Visitors – Top 25 Countries

Site Statistics • UCAIug Site – Size: 305 Mb – Site Accounts: 2, 662 (adding 3 -4 per day) – Bandwidth: 233 Mb/day (uploads/downloads) • CIMug Site – Size: 2. 923 Gb – Active Users: 1150 – Bandwidth: 282 Mb/day • IECTC 57 Site: – Size: 1. 837 Gb – Active Users: 410 – Bandwidth: 713 Mb/day

How Can Utilities Get Involved? • Promote CIM-based integration as your company standard, to reduce project costs • Attend a CIM Users Group meeting tutorial • Join UCA International Users Group • Participate in projects to extend the CIM • Participate in interoperability tests • Think long-term • Don’t settle for less than your company deserves

Sample UCAIug Members Currently 139 companies in 45 countries

CIM-Based Integration for the Smart Grid – Fact or Fantasy? Only one of these “environmentally conscious skyscrapers” is not under construction… http: //www. ecogeek. org/content/view/695/

We Don’t Allow This For Wires Why would we allow it for information?
