What is the name of the project that uses clean energy such as wind energy and solar energy to help Beijing Winter Olympics venues?

It should be "Zhangbei Renewable Energy Flexible DC Network Test Demonstration Project".

"Green Olympics" is one of the important concepts of the Beijing Winter Olympics, and it will be a pioneering work in the history of the Olympic Games to use clean energy for power supply in all venues.

In order to ensure the green power supply for the Beijing Winter Olympics, China has made technological innovations in many aspects. After years of practice and exploration, all 26 venues in the three major competition areas of Beijing Winter Olympics have achieved green power supply, mainly provided by photovoltaic power generation and wind power generation in Zhangjiakou, Hebei. This is not only the first time in the history of the Olympic Games, but also an important breakthrough in the history of human energy.

To this end, China has innovatively developed and built Zhangbei renewable energy flexible DC power grid test and demonstration project, connecting scattered wind farms and photovoltaic power plants in Zhangbei area into an organic whole. This project adopts the new technology of flexible DC power grid originally created by China, and has created 12 as the first in the world. It has the characteristics of strong controllability, fast power regulation and flexible operation mode, which can effectively suppress AC voltage fluctuation and reduce the influence of power fluctuation on the receiving power grid, and become the "golden key" to solve the problem of large-scale grid-connected consumption of new energy.
