Abstract
Disclosed are an on-grid/off-grid scheduling method and apparatus, and an energy storage power supply system. The method is applied to the system. The system includes an energy storage device; the energy storage device is connected to a direct current bus; one end of the direct current bus is connected to a power grid by means of an AC-DC module, and the other end is connected to a load. The method includes: after the energy storage device enters an off-grid operation mode, controlling an output voltage of the energy storage device to decrease once every first preset duration; and every time the output voltage of the energy storage device is controlled to decrease, obtaining an input voltage change situation of the load, and determining, according to the input voltage change situation of the load, whether to control the energy storage device to switch to an on-grid operation mode.
