Focus Of SG-Systems NIST Conceptual Model [Source: NIST Interim Roadmap]

Business Drivers Interoperability requires many standards in a profile stack Work with relevant SDOs per layer of profile stack (e.g., information standards, security standards, transport standards, media standards, etc.) to ensure complete solutions for in- scope interfaces. Need formal industry standards, but the SDO process is relatively slow & needs more user input Work collaboratively with SDOs to ensure common user requirements are appropriately addressed Facilitate standards development by proposing potential solutions for addressing gaps in existing standards. The SDO ultimately determines when and how its standards are updated based on input. For Information Standards, resolve (don’t add to) semantic chaos Avoid having the same information defined with different names, varying definitions, etc. Ensure same information standards can be used across different communication profiles While mapping to other standards will be unavoidable, strive to use, correct and extend one information model standard: The IEC TC57 Common Information Model (CIM) is the default information model for this purpose. There is substantial information overlap among AMI, ADE, HAN and ADR While requirements and services vary significantly, they can be built using the same information model. To ensure consistency of information across all domains, SG-Systems WG is assigned the task of defining requirements and proposing solutions to gaps in existing standards.

SG-Systems WG Scope SG-Systems WG: The SG-Systems Working Group defines requirements, policies, and services, based on utility industry standards such as the Common Information Model (CIM), required for information exchange from and to utility enterprise back office systems and between these back office systems and data acquisition and control servers (e.g., MDMS, AMI Head Ends, SCADA, etc.). Task forces are established on an as needed basis to accomplish these goals for specific functional areas. In addition to work performed by their ‘vertical team,’ Task Force Chairs act as matrix managers to ensure their functional requirements are met through the ‘horizontal teams’ supporting them. ‘Horizontal Teams’ are ongoing, providing consistent artifacts for each increment of functionality that is requested of them by the functional (vertical) teams.

Key Collaboration Concept for the SG-Systems Working Group Standard building blocks are defined by CIMug and the affiliated IEC working groups along with other relevant industry groups e.g., Open Applications Group (OAG), MultiSpeak, OGC Requirements (use cases) are gathered from helpful sources Utilities Industry initiatives The SG-Systems WG articulates Industry Best Practices (see next slide) that satisfy requirements through the use of standard building blocks. Recommended extensions and changes to standard building blocks are provided back to appropriate standards bodies.

Our Focus: Finding/Developing Best Practices & Making Them into Vetted “Industry Best Practices” Local Utility Projects Consortiums & User Groups like OpenSG (business requirements) & CIMug (optimization & implementation support) Standards Development Organizations (SDOs) like IEC TC57 Working Group 14 for the IEC series of standards Utility’s Projects - Design & Implementations Utility’s Architecture Industry Best Practices Interoperability Testing Industry Best Practices Standards Conformance & Interoperability Testing Industry Standards

Remarks on Working Closely With SDO In recent NIST discussions, there is general agreement that formal standards are needed. While IEC is viewed as necessary, it suffers from two major criticisms: The IEC process is too slow There is not enough user participation in IEC standards development IEC TC57 helped form the UCAIug. OpenSG is a user-driven organization that functions as part of the UCAIug OpenSG is able to work with the IEC to resolve these two criticisms: OpenSG ballots its work products and make them publically available as an “Industry Best Practice” Please note that these are NOT standards as OpenSG is not a standards development organization (SDO). OpenSG work products are intended to become a common best practice based on applicable industry standards. Extensions to standards that were needed to meet OpenSG’s business requirements will be provided to the appropriate SDO (e.g., IEC TC57 WG14). The OpenSG hopes that the SDOs will accept its recommended extensions (and the extension will become part of the next release of the standard(s) In the meantime, the user community has something to leverage that is far better than custom extensions performed differently at each individual utility.
