Abstract
A micro-grid dynamic stability control system includes: a micro-grid dynamic stability control device, configured to calculate a power factor based on a real-time voltage and current of a bus; a central control device, configured to transmit a reactive power control instruction if the power factor is lower than a predefined threshold; and at least one local control device, configured to transmit a control signal to the micro-grid dynamic stability control device and at least one distributed power supply controlled by the at least one local control device. In response to the control signal, the micro-grid dynamic stability control device compensates the voltage of the bus with droop control, and the at least one distributed power supply outputs a reactive power to the bus to increase the power factor of the bus.
