The reporter learned from the Smart Grid Pavilion of the Xi'an World Horticultural Exposition that in order to solve the difficult problem of transmission difficulties in the energy grid in western China and in the eastern province of electricity, the State Grid Corporation of China is accelerating the construction of UHV power grids as the backbone grid, and coordinated development of power grids at all levels. , "Intelligent smart grid" featuring information, automation, and interaction.
UHV power grid refers to a transmission network that communicates 1000 kV and DC ±800 kV and above voltage levels. It has the advantages of large capacity, long-distance, low-loss, and small footprint, which can enhance the ability of large-scale energy optimization and configuration. Sustainable energy supply. It can realize the access and coordination of clean energy such as wind power and solar power generation, promote its rapid development, and promote energy conservation and emission reduction.
It is reported that China's UHV power grid construction has made new breakthroughs. Jindongnan-Nanyang-Hubei Jingmen 1000 kV AC, Sichuan Xiangjiaba-Shanghai ±800 kV DC transmission demonstration projects have been completed and put into operation. UHV transmission is clearly included in the national "Twelfth Five-Year Plan" outline. During the “Twelfth Five-Year Plan†period, the State Grid will plan to build “three vertical and three horizontal†UHV backbone grids and 13 DC transmission projects to form a large-scale energy distribution pattern of “West Power Transmission to the East†and “Northern Power Transmission to the Southâ€. . The combination of this grid and the smart grid makes China expected to take the lead in the smart grid field. By 2015, a strong smart grid will be basically completed, achieving a scale of 100 million kilowatts of wind power and 5 million kilowatts of photovoltaic power generation. (Reporter Tan Linmao)
