美国智能电网建设概况

Preview for the Construction of Smart Grid in America

美国电力系统的现代化势在必行。智能电网将替代目前过时的电力系统并运用适时双向通讯技术，实现用户与供电方的直接联络。智能电网可望节省能源、降低成本、提高能效、降低美国对外国石油的依存度并促进可再生能源的利用。奥巴马政府已决定将建设智能电网作为降低能源成本、提高国家能源自主性和减少温室气体排放的关键措施之一。

It is necessary for America to modernize electric system. A Smart Grid would replace the current outdated system and employ real-time two-way communication technologies to allow users to connect directly with power suppliers. The Smart Grid is expected to save energy and consumers＇ money and reduce America＇s dependence on foreign oil by improving efficiency and spurring the use of renewable energy. The Obama Administration has made a smart electrical grid a key element of its plan to lower energy costs, achieve energy inde- pendence and reduce greenhouse gas emission.
