As a new power to help the stable operation of the power grid, efficient energy storage batteries are gradually becoming an important part of the modern power system. Traditional power systems often face problems such as energy supply and demand imbalance, power load fluctuations, and efficient energy storage batteries can effectively solve these problems. It can store electrical energy when the power load is low and release electrical energy at the peak, so as to balance power supply and demand and maintain the stable operation of the grid. In addition, efficient energy storage batteries can also quickly respond to the dispatch needs of the grid, improving the flexibility and reliability of the power system. With the continuous progress of technology and the expansion of application scope, efficient energy storage batteries will play a more important role in the construction of future power grids.
