Abstract

The invention provides a cell apoptosis algorithm-based dynamic recovery system and method of a power distribution network. The cell apoptosis algorithm-based dynamic recovery system comprises an information acquisition agent module, a load agent module, a repair team agent module, a data processing agent module, a restorability estimation agent module, a candidate restoring tree agent module, a synergic agent module and a control center agent module. According to the cell physiological property, the network reconstitution and repair problem is decomposed to a plurality of continuous steps, the optimization difficulty of each step is reduced, and the problem of optimization of a traditional method for many times to easily cause dimension difficulty is solved; according to a restorability estimation value, a recovery mode of a candidate restoring tree at each time frame is determined, a recovery target which is the more important to the stage is determined according to each mode, and the problems of optimizing complexity of the recovery process and long recovery time caused by multi-target optimizing are simplified during the recovery process; and fault recovery and repair are coordinated to consider a recovery scheme, the recovery efficiency is improved, the economic loss is reduced, and the cell apoptosis algorithm-based dynamic recovery system is applicable to the problem oflarge-area power failure of a multi-fault large-power grid system.

Description

technical field [0001] The invention belongs to the field of power grid evaluation, and in particular relates to a distribution network dynamic recovery system and method based on an apoptosis algorithm. Background technique [0002] The fault recovery process of distribution network is a multi-objective optimization problem involving many factors. From the perspective of mathematical optimization, its scale is large and difficult. As the scale of the power grid becomes larger and larger, the scale of power outages caused by natural disasters or other accidents is also increasing. In this case, the power sector requires not only fault recovery but also The emergency repair of faults requires not only the optimal recovery strategy, but also the optimal emergency repair strategy. However, there are still relatively few experts and scholars who study the two issues of failure and emergency repair together. Considering the two issues together is conducive to finding the optimal...
