| description | The invention relates to the technical field of direct-current micro-grids, in particular to a direct-current micro-grid control method and system and a ship power system. The DC micro-grid control method comprises a DC micro-grid construction step, a voltage compensation droop control step, a virtual DC motor control step and an output current P I control step. According to the method, the phenomenon that the voltage of the direct-current bus is increased or decreased in the steady-state process of the load can be effectively solved by introducing the voltage compensation droop control step, the voltage fluctuation in the transient state is reduced by introducing virtual direct-current motor control, and the voltage and power fluctuation can be well stabilized; load power fluctuation and abrupt change conditions under different working conditions are effectively handled, and the safety and stability of the DC micro-grid system are greatly improved.
