  1. WG1-N1605 Facility Smart Grid Information Model • Steven T. Bushby • Engineering Laboratory

  2. ASHRAE/ NEMA Partnership The proposed FSGIM is based on industry needs identified at part of the SGIP PAP 17 Being developed jointly by ASHRAE and NEMA under ASHRAE ‘s ANSI approved procedures Parallel international standardization in ISO/TC 205 Building Environment Design

  3. P PURPOSE: The purpose of this standard is to define an abstract, object-oriented information model to enable appliances and control systems in homes, buildings, and industrial facilities to manage electrical loads and generation sources in response to communication with a “smart” electrical grid and to communicate information about those electrical loads to utility and other electrical service providers. 3

  4. The model will support a wide range of energy management applications and electrical service provider interactions including: (a) on-site generation, (b) demand response, (c) electrical storage, (d) peak demand management, (e) forward power usage estimation, (f) load shedding capability estimation, (g) end load monitoring (sub metering), (h) power quality of service monitoring, (i) utilization of historical energy consumption data, and (j) direct load control. 4

  5. Participants in the Process • Commercial/Institutional/Industrial Producers • Appliance, Residential Automation, and Consumer Electronics Producers • Consumers — Residential, Commercial, and Industrial • Utility • General 5

  8. Builds on Other Standards Significant portions of the FSGIM model are built from related industry standards including: • IEC 61850 • NAESB energy usage information standards (based on CIM) • OASIS EMIX • OASIS Energy Interoperation • OASIS WS-Calendar • WXXM

  9. Seed Standard for Protocol-Specific Standards The intended users of the FSGIM are other standards bodies developing or maintaining control protocol standards in various types of facilities. The model is being developed in a normative UML representation to facilitate the use of electronic tools. The text version of the standard is generated in a (mostly) automated way from the UML model.

  10. What Role Does the FSGIM Model Play?

  11. Overview of FSGIM Structure • Clause 1-3 – Purpose, Scope, Definitions • Clause 4 FSGIM Structure and Usage – background information to guide reader • Clause 5 Model components • Meter Component – and abstract representation of any device that measures electricity or emissions; • Load Component -- an abstract representation of any device that consumes electricity; • Generator Component -- an abstract representation of any device that produces electricity; • Energy Manager Component -- an abstract representation of any device that makes control decisions about energy generation or consumption; and • Weather Component -- an abstract representation of weather measurement and forecast information.

  12. Overview of FSGIM Structure Clause 6 Primitive Types, Classes and Enumerations Clause 7 Conformance Requirements Clause 8 References Annex A – UML Model (Normative) Annex B – UML Basics (Informative) Example Use Cases

  13. Conformance

  14. Conformance • Conformance to the FSGIM ensures that a facility communications protocol conforms to one or more conformance blocks derived from the FSGIM abstract model. • A conformance block is a collection of classes and attributes and behaviors derived from the components within the FSGIM abstract model. • Conformance blocks are intended to contain a concrete set of related functionality within a model component. • A complete set of conformance blocks contains the entire set of attributes and behaviors of a FSGIM model component.

  15. Conformance • In order to be conformant to the FSGIM, an SSO shall be required demonstrate the following requirements: • The SSO shall document any restrictions on the range or resolution of the FSGIM data types that are used. • The SSO shall document the conformance blocks for which they conform. • The SSO shall identify how required and optional attributes in each conformance block is represented in their standard. • The SSO shall document how their standard satisfies the behaviors for the conformance blocks. • The SSO shall document how its conformance procedures will ensure that a device implementation can specify conformance to the FSGIM and how the SSO’s conformance testing will ensure compliance.

  16. SPC 201P Development Timeline • SPC formed July 2010 • 1st meeting August 2010 • Advisory public review December 2012 • Publication public review expected in summer 2013 • The SPC 201P committee meets monthly Goal: Published Standard in 2013 16
