The Overview of Smart Grid

Abstract

Smart Grid is the newest direction of electric power development, and is regarded as the significant technology innovation and development trend of the electric power system in 21st century. It is also regarded as the inevitable result of the development of economic and technology. It has flexible, clean, safe, economical, and friendly functions. Smart grid is a new "second generation" network, which is built on an integrated basis of two-way high-speed communication networks, through the application of advanced sensing and measurement techniques, equipment technology, control technology and decision support system technology in order to achieve reliable, safe, high-quality, economical, efficient, environmentally friendly and safe using target. Smart Grid’s background, significance key technologies, technical difficulties and prospects are introduced in this paper.
