People’s Daily, Beijing, December 5 (Reporter Wang Hao) The reporter learned from China Three Gorges Group Co., Ltd.: Recently, one of the first batch of large-scale wind power photovoltaic base projects started construction during the 14 th Five-Year Plan period, the largest photovoltaic sand control project in China — — The 2 million kilowatts photovoltaic sand control project in Kubuqi, Mengxi base, was successfully connected to the grid.
The project is located in the hinterland of Kubuqi Desert in Hangjinqi, Erdos City, Inner Mongolia, with an installed capacity of 2 million kilowatts, covering an area of 100,000 mu, with an average annual power generation of about 4.1 billion kWh, saving about 1.23 million tons of standard coal and reducing carbon dioxide emissions by about 3.19 million tons each year. The project adopts advanced technologies such as minimally invasive airflow tree planting method, wind direction data method, aerial seeding by unmanned aerial vehicle and so on, and repairs an area of 100,000 mu in desert control.
This project is the first photovoltaic sand control project in China, in which flexible scaffold materials are widely used in desert areas. The project adopts the three-dimensional ecological photovoltaic sand control mode of "double-sided power generation on the board, double-layer ecology under the board and double-layer cultivation between the boards". Double-glass module can realize double-sided power generation on the board, which can increase the power generation by 5% to 10%; Planting high-quality herbage and medicinal materials under the board; The technology of "coupling livestock, poultry and grass" is used between boards to raise chickens first and then sheep. The successful grid connection of the project will help to improve the ecological environment of the Yellow River "Zigzag Bend" and Kubuqi Desert, and provide valuable experience for the popularization and application of photovoltaic sand control technology in desert areas.
