State Grid Wind Power Integration has invested 48.5 billion lines and has a length of 25,000 kilometers

The reporter learned from the China Power and Energy Symposium organized by the State Grid Energy Research Institute recently that in order to fully ensure the timely integration of wind power, the State Grid Corporation has invested a total of 45.8 billion yuan to build 25,000 kilometers of wind power grid-connected lines and substations. 420 seats.

The data shows that since 2006, the nation’s newly installed wind power capacity has reached 54 million kilowatts, which has grown from 1.27 million kilowatts in 2005 to the current 55.07 million kilowatts, a cumulative increase of 42 times, and the newly installed capacity accounts for about 35% of the global same period. World number one. Established a world-class wind power base of over 5 million kilowatts, such as Mengdong, Mengxi and Jiuquan of Gansu Province. The main indicators such as the installed capacity of wind power and the daily wind power generation output are equivalent to the countries with the highest level of wind power operation, such as Spain and Denmark, reaching world advanced levels. .

Wang Min, deputy general manager of the State Grid Corporation of China, member of the Party Committee, and chairman of the labor union, said that the achievements made in wind power development in China have not come by easily. The State Grid Corporation of China has carried out a lot of fruitful work: intensifying efforts to promote the construction of wind power grid connection lines; Optimize the scope of allocation, focus on solving key issues such as difficulties in the dismantling of wind power in China; strive to promote sustained and healthy wind power development, compile 22 corporate standards, fill domestic gaps, and compile 8 million kilowatt-class wind power base transmission plans; actively promote technological progress and Industrial upgrading will be completed with the completion of the world's advanced level national wind energy storage demonstration project, the national wind power technology and testing center, and the development of key technologies for new equipment such as large-scale battery energy storage.

Wang Min believes that the development of new energy power generation in China has two major constraints. First, safety issues, wind power, and solar photovoltaic power generation have significant randomness and intermittency, and large-scale grid-connected networks will pose challenges to grid security. The second is to eliminate the problem. China's wind power, solar energy resources and conventional energy resources are basically the same structure, and their local absorption capacity is weak. To adapt to the rapid development of new energy power generation, it is necessary to speed up the construction of a strong smart grid with a stronger safe carrying capacity and at the same time accelerate the construction of supporting power grids. In particular, the construction of a number of UHV projects for the delivery of wind power, relying on a strong smart grid, will be greater. The market consumes wind power.
