Abstract
With the increasing penetration rate of renewable energy in China's power system in the future,the stability of the system will face more severe challenges.Long-term energy storage technology plays an important role in balancing grid demand,improving grid stability,promoting the consumption of renewable energy,and promoting green and low-carbon development in the power system.Long-term energy storage has a wide range of application scenarios on the power supply side,grid side,and load side of the system,which is of great significance for the development of China's new power system.Firstly,the characteristics and development trends of the current new power system are introduced,and the supporting role of long-term energy storage technology in the new power system is analyzed.Then,the technical principles and routes of five long-term energy storage technologies,such as the compressed air energy storage,lithium-ion battery energy storage,liquid flow battery energy storage,molten salt energy storage,and hydrogen energy storage,are summarized.The advantages and disadvantages of various long-term energy storage technologies are also analyzed.Finally,the future application prospects of long-term energy storage technology in the new power system are discussed.关键词
