Description

Technical Field

[0001] The present invention relates to the field of energy storage technology, and in particular to a matrix-type large-scale compressed gas storage system. Background Art

[0002] Due to the intermittent and random fluctuations in renewable energy generation, large-scale grid integration of wind and photovoltaic power can significantly impact the safe and stable operation of the power grid. Consequently, the phenomenon of wind and solar power curtailment has intensified with the rapid growth of renewable energy generation, resulting in significant resource waste. The efficient and stable utilization of renewable energy generation has become a hot topic of research. Storing excess electricity using the compression potential of readily available, inexpensive compressible gases like air and carbon dioxide has become a promising energy storage technology due to its large scale, low cost, environmental friendliness, and limited location restrictions.

[0003] The basic principle of compressed gas energy storage is to use excess electricity that the grid cannot absorb to drive a compressor, compressing and boosting the gas's pressure before transferring it to a storage system for storage, converting electrical energy into the gas's compression potential energy. When the grid has the capacity to absorb the energy, the compressed gas in the storage system is released and transferred to a turbine, which drives electricity generation, converting the gas's compression potential energy into electricity. Leveraging the bidirectional regulation of this process not only improves the safety and stability of grid operations but also increases the utilization and economic efficiency of renewable energy generators such as photovoltaic and wind power. This will significantly contribute to further optimizing my country's energy structure and alleviating the pressure to save energy and reduce emissions.

[0004] As the core system in these processes, the cost and technical reliability of compressed gas storage systems will have a decisive impact on the development of energy storage technologies using compressed gas as a storage medium. According to general industrial principles, larger installations have lower unit construction costs and greater competitiveness. Therefore, developing large-scale compressed gas storage systems to reduce unit costs and improve competitiveness is imperative to adapt to the trend of large-scale development of new energy technologies.

[0087] The present invention relates to the field of energy storage technology, specifically to a matrix-type large-scale compressed gas storage system. The goal is to utilize limited construction space to achieve large-scale compressed gas storage (>1,000 cubic meters (water volume)), thereby absorbing excess electricity, smoothing grid fluctuations, and improving the economic efficiency of renewable energy power generation. Multiple base frames are arranged in parallel, and gas storage vessels are laid out in multiple layers along the height of the frames, forming a gas storage vessel matrix. Each layer consists of multiple parallel gas storage vessels.
