Abstract
Disclosed herewith is a voltage coordinated control method for an AC/DC distribution system, including steps of: acquiring an actual voltage and an actual current at a DC-side of a converter of the system to obtain a first DC voltage and a first DC current; generating a present reference current signal for the converter according to a voltage-current droop control model, and generating a first control signal to control an output state of the converter; and acquiring an actual voltage at a DC-side of an energy storage adapter in the system to obtain a second DC voltage, generating a present reference power signal for the adapter according to a voltage-power droop control model, and generating a second control signal to control an output state of the adapter.
