(Winter Olympics asked "Ji") Where is the difficulty in supplying 100% green electricity to all venues of the Beijing Winter Olympics?
China News Service, Shijiazhuang, January 23. During the Beijing Winter Olympics, all venues in the three major competition areas will use green electricity, which means that for the first time in the history of the Olympic Games, all venues will be supplied with 100% green electricity.
Which of these problems need to be overcome?
Zhangjiakou, Hebei, as a national-level renewable energy demonstration zone approved by the State Council, has unique advantages in the new energy industry.
Zhangbei is very rich in wind power and solar power generation resources, and is the "hometown of wind and ocean of light".
It is only 200-350 kilometers away from the Beijing Load Center. The development conditions are very favorable. The developable wind energy resources can reach more than 40 million kilowatts and the solar power generation can reach more than 30 million kilowatts.
As a clean energy supporting project for the Beijing 2022 Winter Olympics, the Zhangbei Flexible DC Power Grid Project focuses on green Olympics, connecting Zhangbei New Energy Base, Fengning Energy Storage Power Supply and Beijing Load Center reliably to fully meet the power consumption of Beijing Winter Olympics venues Demand to help Beijing Winter Olympics venues achieve 100% green power supply for the first time in Olympic history.
It is understood that due to the inherent randomness and volatility of new energy, large-scale new energy grid connection is a worldwide problem.
The flexible DC grid technology is the "golden key" to solve the problem of large-scale grid connection and consumption of new energy, and it is one of the most critical technologies for effective energy control and efficient conversion.
The Zhangbei Flexible DC Power Grid Project adopts my country's original and world-leading flexible DC power grid technology. With the flexible DC power grid as the center, through multi-point aggregation, multi-energy complementarity, time-space complementation, and source-grid-load coordination, it can realize free fluctuations on the new energy side. Controllable and stable power supply on the power generation and load sides.
According to reports, the project is the world's first DC power grid project with network characteristics. The core technology and key equipment are the first in the world. The project applies the most advanced power production, transmission, storage, consumption and operation control technology, creating 12 It is the world's first, and has achieved three major breakthroughs: breakthrough in the construction of flexible DC power grids, breakthrough in the improvement of flexible DC capacity, and breakthrough in the improvement of flexible DC reliability.
The Zhangbei Flexible DC Grid Project not only has significant innovation leading and demonstration significance, but also has significant comprehensive benefits and strategic significance for promoting energy transformation and green development, serving green Olympics, leading scientific and technological innovation, and promoting the transformation and upgrading of electrical equipment manufacturing.
