Smart grid is the intelligence of power grid, also known as "Power Grid 2.0". It is based on an integrated high-speed two-way communication network. Through the application of advanced sensor measurement technology, advanced equipment technology, advanced control method and advanced decision support system technology, the goal of reliable, safe, economical, efficient, environmental protection and safe use of power grid is realized.

The main features of smart grid include self-healing, encouraging and containing users, resisting attacks, providing power quality to meet the needs of users in 2 1 century, allowing access to various forms of power generation, starting the power market, and optimizing and efficient operation of assets.

The trend of smart grid

During the "Twelfth Five-Year Plan" period, State Grid will invest 500 billion yuan to build a "three horizontal and three vertical" UHV backbone power grid and a 13 long-distance tributary transmission project connecting large energy bases with major load centers, with the core initially completed.
