A Review of Development and Demonstration Application of Large-scale Electrochemical Energy Storage
With the rapid development of energy storage technology, the large-scale energy storage system has gradually become a key method to ensure power system reliability and safety, of which electrochemical energy storage has been one of the directions of preferential development due to its unique performance. In order to promote the development of energy storage technology and speed up the efficient use of large-scale energy storage system, several large-scale electrochemical energy storage demonstration projects have been successively started and completed in the world. The classification and working principle of electrochemical energy storage technologies are introduced, the main demonstration plants of large-scale energy storage system in China and abroad are summarized, as well as the installation site, scale and function in grid of electrochemical energy storage are pointed out. Then, the characteristics of main electrochemical energy storage, such as lead-acid battery, redox flow battery, sodium-sulfur battery, lithium-ion battery and so on, are comprehensively expounded. Finally, the existing problems, technical direction and future development trend of large-scale energy storage system are discussed and prospected.
