Pre-disaster first-aid repair personnel pre-deployment method for improving power grid recovery speed

The invention provides a pre-disaster first-aid repair personnel pre-deployment method for improving the power grid recovery speed, which comprises the following steps: 1) after predicting an imminentdisaster, obtaining the fault probability of each element according to a power grid element vulnerability curve in combination with meteorological prediction and the geographic information of a powergrid, and generating a fault scene under the disaster through sequential Monte Carlo simulation; 2) acquiring information of a power grid, a repair team and deployable positions, establishing a two-stage stochastic programming model, formulating a deployment scheme of first-aid repair personnel in the first stage, and performing repair and recovery collaborative optimization according to a faultscene in the second stage to minimize power failure loss; and 3) carrying out decoupling solution on the two-stage stochastic programming model through a Progressive Hedging (PH) algorithm. Accordingto the invention, before the
