NIST (from section 1305 (a) of EISA)

INTEROPERABILITY FRAMEWORK—The Director of the National Institute of Standards and Technology (NIST) shall have primary responsibility to coordinate the development of a framework that includes protocols and model standards for information management to achieve interoperability of Smart Grid devices and systems. Such protocols and standards shall further align policy, business, and technology approaches in a manner that would enable all electric resources, including demand-side resources, to contribute to an efficient, reliable electricity network.

FERC (from section 1305(d) of EISA)

STANDARDS FOR INTEROPERABILITY IN FEDERAL JURISDICTION—At any time after the [NIST’s] work has led to sufficient consensus in the Commission’s judgment, the Commission shall institute a rulemaking proceeding to adopt such standards and protocols as may be necessary to insure smart-grid functionality and interoperability in interstate transmission of electric power, and regional and wholesale electricity markets.

Mandate

NIST established the SGIP in 2009 to help fulfill its

EISA 2007 obligations

SGIP has produced and maintains a “catalog of standards” Compendium of standards and practices for the

development and deployment of an interoperable Smart Grid

Key source of information for NIST to identify standards for the Smart Grid as a part of its EISA 2007 responsibilities

standards, practices and guides in the catalog Procedures to approve the addition of an entry to the

catalog, maintain and update catalog entries, and deprecate and/or remove an entry from the catalog

SGIP V2G Working Group: PEV Roadmap Framework

Roadmap Framework: Four Stages

Define stages of evolution to communicate requirements for moving from one stage to the next.

Stages of PEV evolution

Stage 1 PEV Introduction and Impact Assessment

Stage 2 Faster and Smarter Charging

Stage 3 Bi-directional Power Flow

State 4 PEV as a fully integrated DER

Roadmap: Goals and Key Process Areas

Set goals to be attained at each stage.

Goals Stage 1

Groundwork for PEV adoption completed

Stage 2 A demand side balanced with supply

Widespread adoption of PEVs

Stage 3 PEVs utilized as power source

Integrated with renewables

Stage 4 Secure and sustainable environment

Roadmap: Goals and Key Process Areas

Define the process areas that are key to the successful completion of each stage.

Key Process Areas

Stage 1 End-to-end acquisition; EVSE standards

Stage 2 Submetering; back-office integration

Stage 3 Physical interoperability; bi-directional

Stage 4 End-to-end integration

RoadMap: Gating factors

We have grouped adoption factors into three broad categories: Technology, Standards, and Market Structures.

Areas of focus

Technology Communications, Measurement, Controls

Standards Reliability, Security, Privacy

Market Structures Billing, zoning, business practices
