Specifically, according to the power utilization priority of the power utilization equipment, the power utilization equipment with the lowest priority is powered off, the endurance of the energy storage battery is determined after the power utilization equipment with the lowest priority is disconnected, and whether the endurance after power off is smaller than the duration of a storm is judged. And under the condition that the endurance time after power failure is still less than the storm endurance time, sequentially disconnecting the power utilization equipment with the previous priority according to the power utilization priority sequence until the endurance time after power failure is not less than the storm endurance time. The cruising ability of the energy storage battery can meet the power demand of the power-driven equipment which is not powered off. And the computer equipment supplies power to the uninterrupted power utilization equipment through the energy storage battery in the energy storage unit to be detected until the storm early warning information indicates that the storm level does not exceed the early warning storm level. The power supply control method can ensure that the energy storage battery can meet the power consumption requirement of the power consumption equipment with higher priority under the storm scene, and improves the power supply control efficiency.

And S506, under the condition that the duration is not less than the duration of the storm, supplying power to the electric equipment through the energy storage battery in the energy storage unit to be tested until the storm early warning information indicates that the storm level does not exceed the early warning storm level.

When the endurance time is shorter than the duration time of the storm, the power is cut off step by step according to the power utilization priority, and the energy storage battery is ensured to supply power to the power utilization equipment with higher priority. When endurance is not less than duration of storm, the energy storage battery is adopted to supply power to the electric equipment, so that the power failure is avoided, the commercial power cannot be adopted, the power utilization difficulty caused by the sudden state that the solar cell panel cannot be used for supplying power in rainy days is avoided, and the power supply control efficiency is improved.
