Abstract

The invention discloses a two-stage power distribution network post-disaster first-aid repair scheduling and load recovery collaborative optimization method and system. The method comprises the following steps: evaluating element damage conditions of a power distribution system; partitioning the fault points; carrying out preliminary recovery by using the distributed power supply, establishing a nonlinear programming model of the preliminary recovery, obtaining a linearized network reconstruction model, and solving to obtain a load recovery result of a first stage without considering a maintenance process as an initial recovery result; solving a collaborative optimization model of first-aid repair personnel allocation and load recovery by taking the maximum load recovery amount and the minimum recovery time as targets to obtain a network reconstruction time sequence change process, a first-aid repair personnel advancing line and a load recovery sequence result of a second stage considering maintenance scheduling; and as a final result for guiding the operation personnel to carry out post-disaster recovery, carrying out collaborative optimization. The post-disaster recovery capability of the power distribution network is improved, the downtime and the economic loss are reduced, and the recovery capability of the power distribution system is enhanced.

Description

Technical field[0001]The present invention belongs to the field of distribution system recovery force, which specifically involves a two-stage distribution network disaster repair scheduling and load recovery co-optimization method and system.Background technique[0002]Natural disasters and artificial attacks such as natural disasters in the world have brought serious impact on the safety operation of the power system, and the disaster has caused great losses to the national economy for a long time. With the frequent development of natural disasters, and the potential threat of human malicious attacks in the international situation is increasing, the power system is increasingly highly highlighted as the country's important infrastructure, and the significance of strategic facilities is increasing. Research on the improvement of electricity system recovery force in the face of extreme events is of great significance.[0003]The power system is directly related to the user load, while t...
