Energy storage power is widely used in the power system, and its unique function makes the power system better balance energy supply and demand and improve the stability of the system. In the power system, the energy storage power supply can be used as a backup power supply to provide timely power support when the power supply is insufficient to ensure the continuous and stable operation of the power system.

At the same time, the energy storage power supply can also be used to cut peaks and fill valleys to reduce the load pressure of the power grid. In the peak hours of power demand, the energy storage power can release the stored electric energy to meet the peak hours of power demand; During periods of low demand, excess power can be stored for emergency use. This flexible energy dispatching mode enables the power system to better cope with various complex situations and improve the quality and reliability of power supply.

In addition, energy storage power can also be combined with renewable energy power generation systems to achieve smooth access and efficient use of renewable energy. Through the storage and scheduling functions of the energy storage power supply, the renewable energy power generation system can operate more stably, reduce the occurrence of wind and light abandonment, and improve the utilization rate of renewable energy.
