Smart cable in order to better match the intelligent cable, and smart grid technology in the world is still in its infancy, there is no common definition. In the Chinese Academy of Sciences opinion, the smart grid is a strong grid of UHV power grid as the backbone, the voltage level of the coordinated development of the grid, based on modern advanced sensor measurement technology, communications technology, information technology, computer technology and control technology and a highly integrated physical grid to form a new grid.
Smart grid construction process is very complex, but the market is huge. According to the latest report Pike investigative agencies, smart grid technology market will grow from $ 33 billion in 2012 to grow to $ 73 billion in 2020, eight years, the cumulative market reached $ 494 billion.
Chinese authorities have formulated a series of policies to support the development of the smart grid, clear the strong and smart grid technology standard roadmap. State Grid Corporation of planning is 2015 basically completed with information technology, automation, interactive features strong smart grid, to form a north, central, east to the receiving end, to the northwest, northeast grid for the sending end of three synchronous network, resource allocation grid capacity, economic efficiency, safety level, technological level and the level of intelligence overall.
