Smart metering and communications via smart grid networks will in principle allow consumers to monitor and change their patterns of consumption to their best advantage. Utilities will also be able to introduce real time pricing measures in which charges can be adjusted continually to take account of considerations of total demand and the integrity of distribution grids. It will also be possible, in principle, to regulate the demand from particular classes of high usage domestic appliances and industrial equipment. The overall objective is that these interactive smart grid networks can be monitored and controlled to enhance the efficiency, reliability, and security of the distribution networks for electricity, gas and water supplies, while assuring consumers of the continuity of supply. Annex 1 Examples of existing standards related to power grid management systems A1.1 IEEE Standards IEEE 802 has a variety of wireless standards that are applicable to first mile applications for power grid management systems. A summary of the technical and operating features of the relevant IEEE 802 wireless standards are given in the tables below.
