Problems solved by technology

On the other hand, the candidate solutions of the final optimization results of many literatures come from the initial optimization results of static reconstruction of each time period, so the optimization results are not the global optimal, which may easily lead to unreasonable selection of reconstruction methods

Abstract

The invention provides a typical scene recognition based dynamic reconstruction method of a power distribution network. The dynamic reconstruction method comprises the steps of determining a weight of an optimal target under each typical scene; performing time division on a daily load curve of the power distribution network to obtain a reconstruction daily load forecast curve; identifying a type of the typical scene to which each time belongs on the reconstruction daily load forecast curve; building a multi-target reconstruction model of each time on the reconstruction daily load forecast curve to obtain an optical switch state of each time on the reconstruction daily load forecast curve; and adjusting the optimal switch state to obtain an optimal dynamic reconstruction scheme of the power distribution network. The reconstruction method proposed by the invention is high in reliability and fast in solution speed, and load change can be dealt with to acquire a targeted reconstruction scheme according to different typical scenes; the reconstruction scheme is optimal and is more reasonable; and the reconstruction stability and reliability of the power distribution network is ensured, the power distribution network after dynamic adjustment conforms more to the demand of actual running of the power distribution network, and the running stability of the power distribution network is improved.

Description

technical field [0001] The invention relates to the field of distribution system automation, in particular to a dynamic reconfiguration method of a distribution network based on typical scene recognition. Background technique [0002] Distribution network reconfiguration is to change the network topology by closing / breaking the segmented tie switches in the network under the conditions of satisfying the constraints of the system (such as topology constraints, electrical constraints, and power supply index constraints, etc.), so as to realize the system Changes in the operating mode, so as to achieve the purpose of optimizing one or more indicators. Depending on whether load changes are considered over a period of time, reconfiguration can be divided into static reconfiguration and dynamic reconfiguration. Since the load of the distribution network is always changing with time, the dynamic adjustment of the network structure according to the change of load is more in line wi...
