Smart Grid Task Force Coordination and CIM Adoption Recommendations

1. IEC TC57 Smart Grid Task Force Ed Dobrowolski for Scott Neumann 16 June 2010

2. Introduction • IEC TC57 WG19 has created a Smart Grid Task Force, with a focus to coordinate TC57 efforts as related to the Smart Grid • Formed in July 2009 in reaction to National Institute of Standards and Technology (NIST) efforts in the US with Scott Neumann and Jay Britton as co-leaders • NIST is facilitating many Smart Grid efforts, which have had significant international involvement • Purpose of this presentation is to: • Provide background • Identify key issues for IEC TC57

3. NIST Roadmap • Efforts in the US are driven by the Energy Independence and Security Act of 2007 • NIST has “primary responsibility to coordinate development of a framework that includes protocols and model standards for information managementto achieveinteroperability of smart grid devices and systems…” • In 2009, a roadmap was developed by NIST • Identification of the importance of CIM and 61850 standards • Recognition of service providers as important entities within the Smart Grid • Principles of Shallow Integration and Loose Coupling

4. NIST Priority Action Plans (PAPs) • NIST initially identified 14 (now 17) areas where prioritized action is needed • Each of these areas has many different stakeholders, including standards development organizations (SDOs) • The IEC is seen as a key SDO

7. IEC CIM • The IEC TC57 CIM is being targeted as ‘the’ IEC CIM • It certainly is the only viable solution for NIST PAPs 8 and 14, and benefits many other areas • Any notion of a ‘common semantic model’ for everything is flawed and unrealistic • There is a danger that high expectations may be set that can not be met by CIM extension efforts in reasonable timeframes • There is also a danger if we try to displace things that work well now for ‘futures’ that are dependent upon CIM extensions that don’t yet exist

8. What should IEC recommend regarding adoption of CIM by Smart Grid initiatives? • A tempting simple line of reasoning… • Smart Grid will clearly benefit from canonical data modeling. • Consistent semantics & Consistent methodology for encoding information exchange payloads. • CIM is the most advanced application of canonical data modeling in the industry. • Therefore, all Smart Grid standards use the CIM for semantic modeling. • Such a recommendation would be a mistake… • It’s too idealistic - CIM is already wrestling to find pragmatic ways to cope with having a broad scope. • We are learning how to manage expansion of CIM to more and more profiles, but we have not fully mastered the problem (other industries are having the same struggle) • There are limited numbers of experienced experts to help with CIM expansion. And many of these are currently volunteer labor, so that their availability is restricted and not predictable. • We need a recommendation that takes reality into account

9. Possible CIM Recommendation Summary recommendations: • Find a way to increase the availability of CIM experts. • Where there is significant overlap with existing CIM content - ‘participate’ in the existing CIM • Where interfaces do not have significant overlap with existing CIM - independently develop models using CIM methodology • Where there is an existing non-CIM semantic, make a judgment call as to how (and if) to harmonize with CIM. • Do not allow any non-CIM models to expand unless it is very clear: a) exactly what their scope is, and b) exactly why that modeling approach works better in that scope. Assumptions: • CIM is the best available example of how to achieve consistent interface semantics. • The all-inclusive CIM UML will continue to evolve with annual updates with the prime directive of maintaining semantic quality.
