Liu Mingzhi: “Three-horizontal and Three-longitudinal” UHV power grids solve the problem of uneven energy distribution

When Liu Mingzhi, Director of Development Planning Department of Tianjin Electric Power Company, took an exclusive interview with Tianjin Net, a guest of the People's Republic of China, he introduced the construction of UHV power grid during the “Twelfth Five-Year Plan” period in China. He said that China's energy distribution is extremely uneven, coal resources are concentrated in the northwest, hydropower resources are mainly distributed in the southwest, wind power, photovoltaic power generation and other renewable energy bases are mostly located in the northwest and northeast regions, and the energy consumption area is east coast city. In response to the adverse distribution of China's energy demand and resource supply, the State Grid proposed the construction of a UHV backbone grid, linking large energy bases and major load centers.

Liu Mingzhi stated that in the next five years, the State Grid Corporation of China will invest 500 billion yuan to build a “three horizontal and three vertical” backbone grid, achieving UHV AC synchronous power grids covering three regions in North China, Central China, and East China, and 13 long-distance distances. Tributary transmission project. "After the completion of the UHV network, it can truly realize large-scale transmission of electric power from the west to the east, and the transmission of electric power from the south to the north. It will play a supporting role in optimizing the allocation of electric power resources."
