ZigBee Smart Energy (SE) is a standard for interconnecting and interoperating devices, via radio frequency, directed towards monitoring, managing and automating energy, gas and water usage. It seeks to be a useful tool for creating “Green Homes”, and is aimed at coordinating energy usage, optimizing its generation and consumption.
The need for real-time communications in Smart Grid scenarios is becoming increasingly important. One of the most common solutions is to have industrial routers send information securely to the different utility control centers.
Telecommunication networks are one of the most important factors for assuring a successful advanced metering infrastructure. The choice of the appropriate technology is not an easy decision for electricity distribution companies. Several questions arise.
PRIME (PoweRline Intelligent Metering Evolution) is a PLC (Power line communication) technology based on the ITU G.9904 specification. It uses OFDM (Orthogonal Frequency Division Multiplexing) technology to provide an efficient physical connectivity to elements that make up a smart grid, employing medium and low voltage power distribution networks that already exist.
An amendment to Spanish law in 2006 requires all domestic electricity meters to include a means for accurate real-time meter readings, as well as remote manageability. These new electricity meters are called smart meters.
