The invention relates to an energy coordination control method of an off-grid direct-current microgrid. The direct-current microgrid is provided with a photovoltaic power generation unit, a wind powergeneration unit, an energy storage unit and a load unit. The direct-current microgrid is divided into a plurality of working modes according to the grade of the direct-current bus voltage, in each working mode, one or more units of the photovoltaic power generation unit, the wind power generation unit, the energy storage unit and the load unit are used for adjusting the voltage of a direct-current bus and keeping the power balance, when the direct-current microgrid is switched between the working modes, the photovoltaic power generation unit, the wind power generation unit, the energy storageunit and the load unit are switched to the corresponding working modes, and plug and play of the direct-current microgrid under the off-grid condition is achieved. Compared with the prior art, the method has the advantages that the method can still work normally without communication to achieve plug and play, the dynamic characteristics of the direct-current microgrid are improved, the system robustness is improved, and the stability of the direct-current voltage is maintained.
