[0002] An energy storage power station is an energy storage device that is integrated into the power grid. In the daily power supply of the power grid, electricity consumption has peaks and off-peaks. During peak times, there is insufficient electricity, and during off-peak times, the amount of power generated is large. An energy storage device is needed to store electricity during off-peak times and provide electricity during peak times.
