The invention discloses a distributed DC microgrid control method. The distributed DC microgrid control method comprises the steps of: obtaining, according to a power state variable of each power source and all power sources communicating with the power source, the power distribution and regulation and correction amount of the power source through error correction; based on the correction amount,correcting a reference voltage to obtain a voltage expected value; based on a voltage expected value and an output voltage, performing error correction to obtain the average voltage regulation and correction amount of the power source; based on the correction amount, correcting the reference voltage to obtain a voltage instruction value; and based on the voltage instruction value of each power source, adopting the droop control to obtain the cut-off control signal of each switch tube in the DC microgrid. The power distribution regulation and correction amount and the average voltage regulationand correction amount are sneaked into the correction of the reference voltage one by one to eliminate the inherent voltage and power distribution deviation of the primary droop control to achieve the power and voltage control of the DC microgrid so as to reduce the communication amount required by the operation of the distributed controller while maintaining the control performance and reduce the communication burden.
