The invention discloses a multi-source coordination control method for a direct-current microgrid. The method is applied to the direct-current microgrid including N distributive power generating units and M energy storing units. The method comprises steps as follows: the M energy storing units perform droop control in accordance with the droop control relation; each of the N distributive power generating units adopts the local measured direct-current bus voltage and the average, shown in the specification, of output current per-unit values of the M energy storing units obtained from adjacent units directly connected with the distributive power generating unit as switching judging conditions for a control mode, so that multi-source coordination control over the N distributive power generating units and M energy storing units is realized; the average of the output current per-unit values of the M energy storing units obtained through a current observer on the basis of a consistency algorithm by the tth energy storing unit is shown in the specification. With the adoption of the method, on the premise that renewable energy sources are used to the greatest extent and energy balance in a direct-current microgrid system is maintained, large-range fluctuation of the voltage of a direct-current bus is effectively reduced, and the quality of system electric energy is improved.
