On October 22, according to CCTV News, China’s first self-developed 10 MW advanced compressed air energy storage system, after 4,000 hours of test operation, was officially connected to the grid for power generation in Bijie, Guizhou. Significant progress has been made in the field of energy technology.

It is reported that this set of advanced compressed air energy storage system technology and equipment are independently developed by China. It has the characteristics of large scale, low cost, long life, not restricted by geographical conditions, and environmentally friendly. It is an energy storage that can be promoted on a large scale. technology. The system compresses and stores the air when the electricity load is low at night, and then releases the high-pressure air to drive the generator to generate electricity at the peak of the day. A maximum of 40,000 kWh of electricity can be generated per day, which is equivalent to the electricity consumption of 3000 households a day. Played the role of power grid peak shaving.

According to Guo Wenbin, an engineer from the Institute of Engineering Thermophysics of the Chinese Academy of Sciences, the storage medium of this system is air only, and there is no risk of sudden explosion. The air pressure storage range belongs to the medium pressure range, and the risk is controllable.

The system is successfully connected to the grid for power generation, which can not only enhance the power grid's ability to regulate peak and valley power loads, but also store unstable wind power, photovoltaic power generation and other new energy sources, which is equivalent to the grid "stabilizer" and "battery".
