Geneva, Switzerland — (METERING.COM) — January 27, 2010 – The ITU-T group working on the G.hn home networking specifications has agreed on requirements for smart grid products, the organization has announced.
G.hn is a next generation wired home networking standard being developed by the International Telecommunication Union’s standardization sector, ITU-T, which supports high speed communication over power lines, phone lines and coaxial cable.
The agreement includes a “low complexity” profile targeted at smart grid applications, including home control and plug-in electric vehicles. The profile identifies a minimum set of G.hn parameters and specifications that define a specific system to meet a targeted set of applications. This will allow manufacturers to develop products that deliver the low power consumption, low cost, performance, reliability, and security that is required for these and other smart grid applications.
Additionally, the profile specifies minimum requirements for features including signal bandwidth, data modulation methods, transmitter linearity requirements, and forward error correction (FEC), while maintaining interoperability with fully featured G.hn products.
Some of the smart grid products that will benefit from the G.hn specification include smart meters, in-home displays and smart thermostats, plug-in electric vehicles, smart household appliances such as washing machines, dryers, dishwashers, heating, ventilating, and air-conditioning systems, and energy system interface devices.
Smart grid applications that will benefit from G.hn include utility-based demand response programs via broadband internet connections or advanced metering infrastructure (AMI), remote troubleshooting, and flexible control of appliances to reduce power consumption during peak periods.
Also agreed was an Appendix to the G.hn standard that provides guidelines for using G.hn in smart grid applications and on how they work with other G.hn connected consumer devices in the home.
The G.hn standard is promoted by the HomeGrid Forum, which has established a smart grid initiative group to help bring a range of G.hn-based devices to the smart grid market and home energy management applications.
