New ITU standards for smart grid have achieved final approval and are now available for download. Recommendations ITU-T G.9955and G.9956 define three international next generation narrowband powerline communications (NB-PLC) standards. The approved family of standards will enable cost-effective smart grid applications such as distribution automation, diagnostic and fault location, smart metering, demand response, energy management, smart appliances, grid-to-home communications and advanced recharging systems for electric vehicles.
The next-generation NB-PLC transceivers defined in the ITU standards family are optimized for the various topologies and characteristics of power grids around the world. Standardized transceivers will provide a ‘smart’ link between electricity and communications networks through their support of the use of power lines as a communications medium. PLC exploits electricity networks’ existing wired infrastructure, greatly reducing the cost of deploying a dedicated communications channel.
Dr Hamadoun Touré, Secretary General, ITU: “The approved ITU NB-PLC family of international standards will be a fundamental building block for realizing a robust smart grid anywhere in the world, and will allow utilities to start immediate deployment of NB-PLC on a worldwide basis.”
