DEVICE POWER SUPPLY METHOD, SYSTEM, AND RELATED DEVICE

The present invention relates to the field of energy technology. Provided are a device power supply method, a system, and a related device. The method comprises: predicting a power load of a device in an electricity price range, the electricity price range being a continuous time period having a consistent electricity price; selecting a power supply policy for the device according to the power load of the device in the electricity price range, a level of power stored by a power storage device at a first time point, and an electricity price at the first time point; and supplying power to the device according to the selected power supply policy. The method takes into consideration electricity prices to enable flexible selection of a power supply scheme for a device, thereby reducing power supply costs for the device. La présente invention se rapporte au domaine de la technologie énergétique. L'invention concerne un procédé d'alimentation électrique de dispositif, un système et un dispositif associé. Le procédé
