Abstract
Abcd...In ing decades, electricity’s share of total global energy is expected to continue to grow,
and more intelligent processes will be introduced into the electric power delivery (transmission and
distribution) networks. It is envisioned that the electric power grid will move from an electrome-
chanically controlled system to an electronically work in the next two decades. A key
challenge is how to redesign, retrofit, and upgrade the existing electromechanically controlled sys-
tem into a smart self-healing grid that is driven by a well-designed market approach. Revolutionary
developments in both information technology and materials science and engineering promise sig-
nificant improvements in the security, reliability, efficiency, and cost effectiveness of electric power
delivery systems. Focus areas in materials and devices include sensors, smart materials and struc-
tures, microfabrication, nanotechnology, advanced materials, and smart devices.
Introduction
Electric power systems constitute the fundamental infra- light, the pressure of wind, or the energy stored at the core of
structure of modern society. Often continental in scale, electric uranium atoms, into electricity, which is no more than a tempo-
power grids and works reach virtually every rary, flexible, and portable form of energy. It is important to
home, office, factory, and institution in developed countries and remember that electricity is not a fuel: it is an energy carrier. At
