＂Planting green wires+new energy+energy storage＂ to ensure the stability of power supply to the grid.

　　CCTV News:On June 11th, China’s first UHV project to send electricity outside the wind power photovoltaic base in desert, Gobi and desert areas — — Construction of 800 kV HVDC transmission project from Ningxia to Hunan started.

　　The total investment scale of Ningdian’s project in Hunan is about 100 billion yuan, starting from Zhongwei in Ningxia and passing through Gansu, Shaanxi, Chongqing, Hubei, Hunan and other five provinces (regions) and one city, with a total length of 1,634 kilometers. The project mainly transports green electricity and clean electricity produced by using clean energy such as solar energy and wind energy in desert, Gobi and desert areas, and has become an innovative project in Ningxia to achieve the goal of "double carbon" and a demonstration project to build a new power system and realize the optimal allocation of new energy in a large scale.

　　It is understood that the total installed capacity of supporting power supply for Ningdian’s project in Hunan is 17.64 million kilowatts, which will promote the transmission capacity of Ningxia power grid from 14 million kilowatts to 22 million kilowatts, and the installed capacity of new energy will exceed 50 million kilowatts, which will greatly promote the local consumption of new energy in Ningxia and optimize the allocation of new energy on a large scale, and fundamentally solve the problem of grid-connected consumption of new energy in central and southern Ningxia. After the project is put into production, it will increase Hunan by 36 billion kwh every year — 40 billion kwh of electricity consumption.

　　Ecological management of "planting green and protecting wires" makes the electric tower stronger

　　Ningdian’s project into Hunan is the first large power channel in China, which mainly focuses on developing desert photovoltaics and transporting new energy. What difficulties did the owner encounter in the pre-planning and current construction process? How is it solved?

　　The total length of Ningdian project in Hunan is 1634 kilometers, and the Ningxia section is 261 kilometers. Among them, 68% of the lines pass through desert, Gobi and desert terrain, which means that some power towers need to be built in the "Shage Desert" area, and the sparse vegetation and complex terrain in the area, coupled with the invasion of sandstorms, will make the power towers fall down, threatening the safe and stable operation of transmission lines.

　　In order to solve this problem, the project owner used the previous experience of UHV operation and maintenance management for reference, and launched the "Green Line Protection" plan.

　　"New energy+energy storage" ensures the stability of power supply to the network.

　　In addition, the engineering construction team also explored the technology of "new energy+energy storage" to solve the technical problem of unstable new energy.

　　In order to master the law of new energy power generation, Ningxia electric power department has stepped up scientific and technological research, developed and established an early warning system, and used artificial intelligence to process and analyze massive data to monitor the operation of new energy power in real time.

　　At the same time, in order to ensure the stable transmission of new energy power, Ningxia electric power system continues to tackle key problems of "new energy+energy storage" technology, providing strong support for project construction.
