Power dispatching system

Abstract

This invention provides a power dispatching system. The power dispatching system includes sensors, functional devices, and a management device. The sensors sense the grid power of the regional power grid to provide sensing signals. The functional devices include a power compensation circuit, a functional circuit, a battery module, and a device controller. The battery module stores battery power and provides it to the functional circuit. The management device notifies the device controller based on the sensing signals, causing the device controller to control the power compensation circuit to use battery power to compensate for the grid power of the regional power grid.
