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

Abstract

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 upcoming meteorological disasters are predicted, emergency maintenance personnel are deployed in the key links of the power grid, so that the emergency response capabilityof the power grid after the disasters is improved, the repair of fault elements is accelerated, and reasonable suggestions are provided for the formulation of power grid emergency plans.

Description

technical field [0001] The invention belongs to the field of power system safety planning and operation, and in particular relates to a pre-disaster repair personnel pre-deployment method for improving the recovery speed of a power grid. Background technique [0002] Frequent extreme weather disasters in recent years have caused large-scale power outages. However, after the typhoon, due to heavy rain, water and other reasons, repair personnel could not quickly reach the repair site, which delayed the restoration of power. [0003] In the face of existing disasters, there is no power grid emergency response capability, and emergency repair personnel cannot be deployed well, which will inevitably cause large-scale post-disaster power outage losses. Contents of the invention [0004] In order to solve the problems existing in the prior art, the purpose of the present invention is to provide a pre-disaster repair personnel pre-deployment method that improves the recovery spee...

AI Technical Summary

Problems solved by technology

However, after the typhoon, due to heavy rain, water accumulation and other reasons, repair personnel could not reach the repair site quickly, which delayed the restoration of power.

[0003] Before the existing disaster occurs, there is no emergency response capability of the power grid, and it is impossible to pre-deploy emergency repair personnel, which will inevitably cause large-scale post-disaster power outage losses
