A power system stabilizing system includes an accident detector, a power restriction target selector, a cutoff controller, and a reconnection controller. The accident detector is configured to detect a system accident of a power system. The power restriction target selector is configured to select power restriction targets which are required for stability maintenance of the power system out of a plurality of power supplies included in the power system or connected to the power system according to a type of the system accident detected by the accident detector. The cutoff controller is configured to cut off the power restriction targets selected by the power restriction target selector. A system restoration checker is configured to check that the power system has been restored from the system accident on the basis of system information of the power system. The reconnection controller is configured to reconnect some or all of the power restriction targets cut off by the cutoff controller when the system restoration checker checks that the power system has been restored from the system accident.
