So, what kind of grid energy storage system is lithium battery used in?

　　The first is the application at the power generation end. Its main function is to smooth the power fluctuation of the new energy power generation end, improve the quality of new energy power, enhance the quality of wind power and photovoltaic power generation, and improve the economic benefits of new energy power generation.

　　The second is the online grid regulation function. Lithium batteries participate in the frequency and voltage regulation or peak regulation of the power grid. As a backup regulation method that can be started quickly, its regulation is fast and flexible.

　　The third is the application on the load side. There is a big difference between the current price of electricity in the peak usage and the low usage valley. It is possible to store low-priced electricity at night through lithium batteries and release it during the peak electricity usage during the day to earn the intermediate difference.

　　The fourth is the application in the microcirculation grid. The two-way regulation of micro-grid operation and the indispensable part of compensation in micro-grid island operation is the energy storage system.

　　The application prospects of lithium batteries in grid energy storage are very promising.

　　Lithium-ion battery (LIB) has become the main energy storage solution in modern social life. Among them, lithium iron phosphate batteries are a perfect replacement for lead-acid batteries, and are the first choice for grid-connected peak shaving, off-grid energy storage, photovoltaic energy storage, UPS, data centers and other industries.
