Abstract
The power grid is evolving into the Smart Grid, by incorporating Information and Communication Technologies (ICT) and new functionalities. Some of the Smart Grid functionalities, such as Advanced Metering Infrastructure (AMI) and Demand Response (DR), require information about customers’ energy consumption and production. Power Line Communication (PLC) is a candidate technology for connecting the customers and utilities as it is easy to deploy and has extensive coverage. ITU-T G.hnem standard defines a narrowband PLC, which was specially designed for Smart Grid applications. This paper proposes a PLC network architecture following the G.hnem standard, which enables bi-directional communication among customers and utilities.
