Abstract

The present invention discloses a coordinated control method for power distribution system with DC bus electrification scheme and apparatus thereof. The method comprises: detecting what kind of disturbances occurs and at least one of following steps: restoring the voltages of the failed DC buses if power loss is detected on the DC buses due to temporary or permanent failures of upstream power supplies; controlling the voltage of the abnormal DC buses if overvoltage or under voltage is detected on the DC buses due to internal or external disturbances; and supporting the voltages of the abnormal AC buses if overvoltage or under voltage is detected on the AC buses due to internal or external disturbances. The methods and apparatus can further improve the fault ride through capability for power plant under external or internal disturbances and facilitate smooth automatic switching process between two DC buses etc.
