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.
