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 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 Click to Learn More about CIM CIMug Site ( CIMug Site ( Recent Presentations Ask for Help FAQs Open a guest account!

CIM Documentation CIM documentation is split into 5 major categories – : Guidelines and General Requirements Describes the component based reference model Includes general capabilities for integration infrastructure – : Glossary – xx: Common Information Model 301: Paper copy of the model – Published yearly by IEC – Latest version: CIM13, v19 – Electronic copy on CIMug web site – 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 – xx: CIS Technology Mappings RDF Schema, Web Services Profile, OWL Schema, XML format, Graphics Exchange

Who is IEC and UCAIug? The International Electrotechnical Commission ( is “the world's leading organization that prepares and publishes International Standards for all electrical, electronic and related technologies” UCA International Users Group ( a non-profit dedicated to promoting standards, has Liaison status with IECwww.ucaiug.org – CIM Users Group ( is one of several groups within UCAIugwww.cimug.org – 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 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…

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

Questions? For further discussion, contact: A new Utility Co-Chair will be appointed at the fall CIMug meeting. – To be held at EPRI offices in Charlotte, NC – Date: November 10-13, 2009 – Official meeting announcement will go out soon…stay tuned to
