Method and system for supplying power to device, and related device

A power supply control apparatus, comprising:

• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to:
• predict power load of a device in a first electricity price interval, wherein the first electricity price interval is a continuous time period in which electricity prices are the same;
• select a power supply policy for the device based on the power load of the device in the first electricity price interval, a quantity of stored electric charges of a power storage device at a first moment, and an electricity price of a second electricity price interval within which the first moment falls;
• and
• send a power supply command to a power supply or the power storage device, to enable the power supply or the power storage device to supply power to the device.

A computing device, wherein the computing device comprises:

• at least one processor;
• and
• one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least one processor to perform operations comprising:
• predicting power load of a device in a first electricity price interval, wherein the first electricity price interval is a continuous time period in which electricity prices are the same;
• selecting a power supply policy for the device based on the power load of the device in the first electricity price interval, a quantity of stored electric charges of a power storage device at a first moment, and an electricity price of a second electricity price interval within which the first moment falls;
• and
• supplying power to the device based on the selected power supply policy.
