Load transfer method based on optimal flow method and Mayeda spanning tree method

InactiveCN111682525AAvoid the disadvantage of slow evolutionAvoid the disadvantage of generating too many bad treesForecastingResourcesLoad SheddingAlgorithm
The invention discloses a load transfer method based on an optimal flow method and a Mayeda spanning tree method. The load transfer method comprises the steps: simplifying a power distribution network, reading faulty distribution network topology, employing a method of combining an optimal flow method and a Mayeda spanning tree method to reconstruct a fault power distribution network. The reconstruction method comprises the following steps: establishing a load transfer target function and constraint conditions; opening a section switch, selecting an available interconnection switch, closing toform a looped network; determining an optimal flow mode at the moment; finding out the section switch branch with the minimum load shedding capacity of the corresponding looped network as the optimalsolution of the corresponding branch; checking whether constraint conditions are met or not: if not, adding the constraint conditions to the target function in a penalty function form, then selectinga new available interconnection switch to replace the previously selected interconnection switch, and repeating the method until the absolute value of the increment of the target function meets preset iteration precision, so as to obtain the optimal topological structure of the load transfer power distribution network. According to the invention, the optimal load transfer scheme can be obtained in a relatively short time.
