Smart Grid (Energy Transmission & Distribution) Smart Grid is a transformed electricity transmission and distribution network or "grid" that uses robust two-way communications , advanced sensors/meters, and distributed computers to improve the efficiency , reliability and safety of power delivery and use. Think of a Smart Grid as an “internet routing network” for Electricity , instead of for Data. The Smart Grid is enabled by the convergence of technologies from several industries 5/8/2011 Prepared by Dr. William Kao 4
