The First Scenery Storage and Transportation Demonstration Project Was Put into Production to Solve the Challenge of New Energy Integration

The National Scenery Storage and Demonstration Project was completed and put into operation in Zhangbei County, Hebei Province on the 25th. This is the first and the world’s largest new energy comprehensive utilization project integrating wind power generation, solar photovoltaic power generation, energy storage, and intelligent power transmission, and is expected to solve the problems faced by China’s large-scale development of new energy. Power generation internet problems.

“The wind turbines generate more electricity at night and the solar panels generate more electricity during the day. Through this demonstration project, the wind and solar power are complemented. In addition, the adjustment of energy storage batteries and the coordination of the smart grid can solve the problem of the randomness and volatility of new energy generation. The conventional coal-fired power generation is stable and controllable,” said Zhao Yuzhu, deputy general manager of the construction contractor and North China Power Grid Corporation, in an interview after the launch ceremony. He also said that through this kind of wind and solar energy storage combined power control, the wind power generation utilization will be increased by 5%-10%.

This National Wind Energy Storage and Demonstration Project is a national “Golden Sun” project, which is independently designed and constructed by the State Grid Corporation of China. The first phase of the project will invest 3.3 billion yuan, and a joint power station supporting 100,000 kilowatts of wind power, 40,000 kilowatts of photovoltaic power generation and 20,000 kilowatts of storage batteries will be completed.

“To realize the large-scale development and utilization of renewable energy such as wind power and solar power generation, we must make every effort to solve the technical difficulties in accepting new energy in the power system.” Xiu Binglin, deputy director of the Department of Science and Technology of the National Energy Administration, believes that promoting the demonstration of wind and solar energy storage and transmission projects Promoting the development and utilization of new energy in our country has a leading role in demonstration. He also stated that the recently released national energy science and technology "Twelfth Five-Year Plan" will focus on supporting the development of technology and industrialization in the fields of transmission and transmission, new energy, etc. in the next five years.

Compared with the more mature wind power industry, the development of photovoltaic power generation and energy storage battery industry is still in its infancy. Zhao Yuhai, Director of the Department of High-tech Development and Industrialization of the Ministry of Science and Technology, said that this demonstration project of wind-storage storage and transmission will be developed into a base for testing various new energy grid-connected technologies in China to promote the development of new energy technologies such as photovoltaic and energy storage batteries. He also disclosed that an industrial policy encouraging gas turbines and pumped storage power stations to participate in new energy peaking and power generation is being studied and introduced.
