Smart grid distribution and smart meters - 4

Introduction Smart grids: a step forward in efficiency Governments and power companies across the world have recognized that the traditional grid, which has not significantly changed in 100 years, must be replaced by more efficient, flexible and intelligent energy-distribution networks, called smart grids. These are digitally monitored, self-healing energy systems that deliver electricity or gas from generation sources, including distributed renewable sources, to points of consumption. They optimize power delivery and facilitate two-way communication across the grid, enabling end-user...

Energy smart meters Smart electricity meters – Overview Smart metering essentially involves an electronic power meter supplemented by full remote control, diagnostics, power peak and consumption analysis, anti-tampering mechanisms, fault alert, time-variable tariffs, and many more possibilities. Using power-line communication (PLC) or other wired and wireless technologies to connect the meter to the service provider enables all of the above features to be feasible and compatible with future smart-grid protocols.

M24LR64-R Dual Interface EEPROM The Dual Interface EEPROM is an electrically-erasable memory which communicates with read and write attributes through both a wired I2C interface with MCU or chipset as well as an RF interface, using the industry-standard ISO 15693 which does not require any on-board power. It enables a wide range of use cases in the smart meter ecosystem. The first is in manufacturing and logistics where you can remotely set parameters at the last minute and update or customize settings when your meter is already in the box. You can also activate keys and trace the...
