Standard Will Integrate Control Technologies into the Grid

June 05, 2016 by Jeff Shepard

The Smart Grid Interoperability Panel (SGIP) announced today the publication of the new ANSI/ASHRAE/NEMA Standard 201P, Facility Smart Grid Information Model (FSGIM), which will open the door for electrical energy consumers to participate in smart grid networks. The standard is packaged with a User's Manual.

The Facility Smart Grid Information Model (FSGIM) was developed in a collaboration by SGIP, the National Electrical Manufacturers Association (NEMA) and ASHRAE (a society advancing the arts and sciences of heating, ventilation, air-conditioning and refrigeration). The 201P FSGIM standard provides a way to model real building systems as a combination of four abstract components: loads, generators, meters and energy managers.

The kinds of functionality that will be enabled by the model include: On-site generation management; Demand response; Electrical storage management; Peak demand management; Forward power usage estimation; Load shedding capability estimation; End load monitoring (sub-metering); Power quality of service monitoring; Use of historical energy consumption data; and Direct load control.

A "facility" in the context of this standard can be a single-family house, a commercial or institutional building, a manufacturing or industrial building or multiple buildings such as a college campus. There is a range of control technology used in these facilities, with standards to support them. The 201P Facility Smart Grid Information Model (FSGIM) provides a common framework to guide the development of these control technologies so that they can meet the control needs of a smart grid environment.

The development of the standard began in 2010, led by Steve Bushby, chair of the Standard 201P committee, and it became SGIP’s Priority Action Plan 17. The American National Standards Institute (ANSI) approved the standard in early May 2016.

"SGIP’s Priority Action Plan (PAP) process is designed to identify standard gaps or needs and to facilitate the development, discussion, and recommendations for Smart Grid-related standards to advance grid modernization," said Aaron Smallwood, director of technology operations for SGIP. "We’re pleased that the Facility Smart Grid Information Model PAP17 resulted in the development and approval of ASHRAE/NEMA Standard 201, and that we now have the opportunity to review Standard 201 for inclusion in SGIP’s Catalog of Standards."

Standard 201P builds on and makes use of several other related standards applicable to the smart grid including: IEEE 61850 (generators); OASIS WS-Calendar; OASIS Energy Market Information Exchange; NAESB REQ Business Practices and Information Models to Support Priority Action Plan 10 — Standardized Energy Usage Information (Green Button); OpenADR; and Weather Exchange Model (WXXM).

In addition, a ballot has been initiated to approve Standard 201P Facility Smart Grid Information Model (FSGIM) as an International Organization for Standardization (ISO) standard, via ISO/Technical Committee 205 Building Environment Design. If approved, the ballot, which is expected to take several months to complete, would move the standard to publication as an ISO standard.
