Post-disaster repair decision-making method and device for a power distribution network

Abstract

The invention discloses a post-disaster repair decision-making method and device for power distribution network. The method comprises the steps of collecting fault information distribution transformerlevel disaster damage information,first-aid repair teams and material transport vehicle information under disaster conditions; on the premise of meeting the distribution network operation constraintand the path planning constraint,using distribution network fault point selection and first-aid repair teams and material scheduling as decision variables,establishing a power distribution network frame reconstruction and material personnel allocation auxiliary decision-making model,wherein the model comprises a lower tie line action scheme determination model taking the maximum recovery load as atarget and an upper construction team and material scheduling scheme determination model taking the minimum total power loss in the rush-repair process as a target; and solving the dispatching auxiliary decision-making model by adopting an upper-lower layer iterative solving method,and finally determining a post-disaster repair decision-making scheme of the power distribution network. According to the method,the problem that the target of minimum economic loss cannot be achieved due to the cooperative action of a construction team and a material vehicle is fully considered,and decomposition codes of all parts are simplified.

Description

technical field [0001] The invention belongs to the field of emergency repair scheduling of electric power systems, and relates to a decision-making method and device for emergency repair of distribution networks after disasters. Background technique [0002] Due to the low design standard of the distribution network, a large number of physical failures of the distribution network will be caused during the occurrence of natural disasters (such as blizzards, typhoons, etc.). In the extreme ice and snow disaster in 2008, the power grids of 16 provinces (autonomous regions and municipalities directly under the central government) suffered serious damage, such as ice-covered lines, collapse of iron towers, tripping of substations, large-scale power outages, etc., and the direct and indirect economic losses caused by broken cables alone Just nearly one billion yuan. After a disaster occurs, the construction team needs to arrange the emergency repair order of the construction tea...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the traditional method of post-disaster emergency repair of the current distribution network is to consider the vehicle path or switch sequence alone, without considering the coordinated action of the construction team and the material vehicle, and often cannot achieve the goal of minimum economic loss.
