The application of energy storage battery in power system is increasingly extensive, but it also faces some challenges. As the "stabilizer" of the power system, the energy storage battery can provide power support when the grid load fluctuates, and smooth the contradiction between power supply and demand. However, the large-scale application of energy storage batteries is still restricted by cost, life, safety and other aspects.

In order to overcome these challenges, it is necessary to increase the research and development of energy storage battery technology, improve energy density and reduce costs; At the same time, strengthen the safety management of the energy storage battery system to ensure its stability and safety during operation. In addition, it is also necessary to improve the relevant policies, regulations and standards system to create a good environment for the wide application of energy storage batteries in the power system.
