Gaithersburg, MD, U.S.A. --- (METERING.COM) --- August 18, 2009 - On the basis of stakeholder input received at three public workshops, as well as reviews of research reports and other relevant literature, the U.S. National Institute of Standards and Technology (NIST) has identified an initial set of priorities for developing standards necessary to build an interoperable smart grid.

Among the criteria for inclusion on this initial list were immediacy of need, relevance to the high priority smart grid functionalities (wide-area situational awareness, demand response, electric storage, electric transportation, advanced metering infrastructure, and distribution grid management), availability of existing standards to respond to the need, state of the deployment of affected technologies, and estimated time frame to achieve an effective solution.

The priorities are:

  • Guidelines for the use of IP protocol suites for smart grid
  • Guidelines for the use of wireless communications
  • Develop common specification for price and product definition
  • Develop common scheduling mechanism for energy transactions
  • Standard meter data profiles
  • Demonstrate common semantic model translations for end device data
  • Energy storage interconnection guidelines
  • CIM for distribution grid management
  • Standard DR signals
  • Standard energy usage information
  • Develop and standardize common object models for electric transportation
  • IEC 61850 objects/DNP3 mapping
  • Time synchronization, IEC 61850 objects/IEEE C37.118 harmonization
  • Transmission and distribution power systems model mapping
  • Smart grid cyber security requirements.

At the most recent of the workshops, held August 3-4, 2009, in Chantilly, VA, more than 20 standards development organizations and other smart grid stakeholders engaged in addressing these priorities. Many individual and collaborative responsibilities for addressing standards issues and gaps were identified. Further, tasks were defined and timelines set for accomplishing many of them.

Finalized versions will be included in the Release 1.0 of the NIST Smart Grid Interoperability Standards Framework, which is expected in September.

An initial list of standards identified for inclusion in the Standards Framework was released by the NIST in May, following the first public workshop (see Standards and other U.S. smart grid developments announced).

The following month, following the second public workshop, a draft smart grid interoperability standards roadmap, identifying issues and proposing priorities for developing technical standards and an architecture for a smart grid, was released by the NIST (see Draft U.S. smart grid interoperability standards roadmap released). Subsequently this document, which will be used in drafting the Standards Framework, has been revised, incorporating comments from more than 80 individuals, companies and organizations.
