The invention discloses a method for evaluating the importance of a power system element based on restoring force. The method comprises the following steps: 1) determining the type and occurrence property of a disaster; 2) obtaining vulnerable element types and related fault probabilities under disasters; 3) acquiring fault configuration conditions of elements in the system after disasters occur by utilizing non-sequential Monte Carlo simulation; 4) establishing a post-disaster optimal recovery strategy model, and proposing an objective function and constraint conditions; and 5) simulating thepost-disaster recovery process for multiple times to obtain the repair time of each element, and performing sorting by using a Koplan sorting method to obtain the importance sorting of the elements.By utilizing the method, the element importance of the power system under various natural disasters and man-made disasters can be solved, and the disaster type and characteristics are considered in the solving process. The element importance result obtained by the method can provide reference for making a post-disaster recovery strategy and determining a pre-disaster element reinforcement scheme.
