Salim Beg Journal on Electrical Engineering 2230 – 7176 4 1 1 7 Smart Grid, Intelligent Grid, Smart Sensors, Intelligent Sensors, Power Grid, Wide Area Measurement The implementation of a smart power grid is at present, an active area of research for different utilities and countries. Functionally, a smart grid should be able to provide new capabilities such as self-healing, high reliability, energy management, and real-time pricing. A smart grid is expected to respond to threats, material failures, and other destabilizing influences by preventing or containing the spread of disturbances. In addition Smart grid can have major impacts on improving energy distribution and optimising energy usage which will result in reduction of CO2 emission. The Smart Grid will rely on smart sensors deployed across the grid to monitor the system and provide data to enable applications. These sensors must be reliable, have low installed cost and leverage existing communications infrastructure that may include automatic metering infrastructure or even the public cellular networks. This article describes the basic features of smart grid and the role of smart sensors and the accompanying technology in the implementation of a smart grid.
