Abstract

This application discloses a method, apparatus, and medium for phased power restoration of a rural AC / DC hybrid microgrid. The method includes: detecting whether at least one distribution section has a fault, and isolating the faulty distribution section when a fault occurs; designating the distribution sections whose power supply was cut off due to isolation as the distribution sections to be restored; collecting first operating status information of the local power supply equipment and isolation information of the faulty distribution section, and determining whether the local power supply equipment meets preset islanding power supply conditions based on the first operating status information and isolation information; if the preset islanding power supply conditions are met, then using the local power supply equipment to supply power to the distribution section to be restored, and restoring power in stages according to the importance level of the load to be restored, thereby realizing the fault restoration of the distribution section to be restored. This application can improve the critical load guarantee capability, power supply continuity, and operational resilience.
