ITU-T G.hn Workgroup Agrees on Guidelines for Smart Grid Applications

TMCnet Contributor


HomeGrid Forum, a global, non-profit trade group promoting the United Nations’ International Telecommunication Union’s, or “ITU-T,” G.hn networking standard, announced that the ITU-T G.hn workgroup has agreed upon a number of key specifications for smart for G.hn Smart Grid products.

The workgroup also agreed on the addition of an Appendix to the G.hn standard that provides insight to the use of G.hn-based products in Smart Grid applications, HomeGrid Forum officials said. 

These agreements were announced at the ITU-T G.hn workgroup meeting held in Valencia, Spain from November 16-20. 

At the Valencia meeting, the G.hn workgroup completed its definition of a ‘low complexity’ profile targeted at Smart grid applications. A profile, according to the workgroup, is a minimum set of G.hn parameters and specifications that define a specific system to meet a targeted range of applications. 

The profile allows multiple manufacturers to develop products that deliver the low power consumption, low cost, performance, reliability, and security that is required for Smart Grid and other lower bit rate applications. 

Additionally, the low complexity profile also specifies minimum requirements for features such as signal bandwidth, data modulation methods, transmitter linearity requirements, and Forward Error Correction, or “FEC,” while maintaining interoperability with fully-featured G.hn products, HomeGrid Forum officials said.

G.hn technology, the next generation wired networking standard developed by the United Nation’s ITU-I, supports high-speed communication over power lines, phone lines and coaxial cable. 

G.hn’s connectivity over power lines, coaxial cabling, and telephone wires provides greater coverage, performance, and reliability throughout the home than technologies that operate over a single wire type. Because of this, the technology enables users to build integrated, whole-home networks. The technology supports virtually all devices that consume energy or share information, say officials at the Forum.

Beyond Smart Grid, G.hn provides a single, unified home networking technology for multimedia voice, video and data communications that is fully interoperable with its Smart Grid derivatives. 

Some of the Smart Grid products that will benefit from G.hn specification include:

  •  Smart Meters
  • In-Home Displays and smart thermostats
  • Plug-in Electrical Vehicles and Electrical Vehicle Supply Equipment
  • Smart household appliances such as washing machines, dryers, dishwashers, heating, ventilating, and air-conditioning systems
  • Energy System Interface devices
Smart Grid applications that will benefit from G.hn include utility-based Demand Response programs via broadband Internet connections or AMI systems, remote troubleshooting systems, in-home device support of automatic Demand Response programs using real-time pricing information, and flexible control of appliances to reduce power consumption during peak periods.

At the Valencia meeting the G.hn work group also agreed on an Appendix to the G.hn standard that provides guidelines for using G.hn in Smart Grid applications and for how they work with other G.hn-connected consumer devices in the home, said officials at HomeGrid Forum. 

The Appendix provides guidance to G.hn product developers and users and describes how G.hn devices can be used as part of application layer Energy Management System software that resides above the G.hn physical layer and data link layer. 

Additionally, the appendix also shows how G.hn Smart Grid devices interface to a service provider’s Smart Grid access network via the Energy Service interface to support secure end-to-end smart grid services between the service provider and home, they said.

“We are happy to see the G.hn workgroup working together to address the needs of the Smart Grid industry with this level of speed and collaboration,” Vladimir Oksman, technical marketing director at Lantiq, and chairperson of HomeGrid Forum’s Smart Grid Workgroup, said in a statement. “G.hn continues to fulfill its promise of complete home networking from the Smart Meter to the HDTV.”

Officials at HomeGrid Forum announced that as a complement to the ITU-T’s work, HomeGrid Forum will provide Smart Grid-related certification testing for G.hn products and this work is underway in HomeGrid’s Compliance and Interoperability Workgroup. 

In October, HomeGrid Forum had announced its G.hn technology has received approval from the National Institute Standards Technologies for use in various smart grid applications. 

After this approval, HomeGrid Forum formed a smart grid initiative group within the organizations to focus on this specific smart grid application, which will help to bring a range of G.hn-based devices to the smart grid market and home energy management applications.
