CIM Standards: Status, Testing, and Collaboration
Randy RhodesCIMug Utility Co-Chair
EMS Users ConferenceSeptember 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 real-
world 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– UML, XML
• Permits software tool usage for:– Defining and maintaining data models
• Single point of maintenance for changes– Documenting data models– Automatic generation of information payloads

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– 61970-3xx: Common Information Model
• 301: Paper copy of the model– Published yearly by IEC – Latest version: CIM13, v19 – Electronic copy on CIMug web site
– 61970-4xx: 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
– 61970-5xx: 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

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
• 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• DigSilent• 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

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
