Distribution network reconstruction method, device and apparatus based on high-dimensional multi-objective evolution algorithm

Abstract

The invention discloses a distribution network reconstruction method based on a high-dimensional multi-objective evolution algorithm. The method comprises firstly determining a distribution network multi-objective reconstruction model corresponding to a distribution network; then solving the distribution network multi-objective reconstruction model by using the high-dimensional multi-objective evolution algorithm to obtain multiple high-quality solutions; and finally, selecting the optimal solution from the high-quality solutions by a predefined rule. Therefore, the method can obtain multiplehigh-quality solutions that satisfy the distribution network multi-objective reconstruction model in one optimization, and finally selects the optimal solution from multiple high-quality solutions. Thus, the method obtains the multiple high-quality solutions in a single optimization so as to provide a decision maker with multiple preselected schemes, in order that the decision maker can further determine the optimal reconstruction scheme that can satisfy the distribution network reconstruction model from the multiple high-quality solutions, thereby improving the reconstruction efficiency of the entire distribution network. In addition, the present invention also discloses a distribution network reconstruction device and apparatus based on a high-dimensional multi-objective evolution algorithm and having the above effect.

Description

technical field [0001] The invention relates to the technical field of power grids, in particular to a distribution network reconfiguration method, device and equipment based on a high-dimensional multi-objective evolution algorithm. Background technique [0002] With the further planning and development of "Smart Grid". The distribution network reconfiguration increasingly needs to comprehensively consider the optimization of multiple distribution network indicators. For the distribution network involving more and more connected devices and more and more complex lines, the reconfiguration model of the distribution network is also It's getting more and more complicated. [0003] Therefore, to solve such a complex distribution network reconfiguration model, if the traditional method is used to solve the distribution network reconfiguration model, only one high-quality solution can be obtained for each optimization. In this way, if the high-quality solution corresponds to the...

[0003] Therefore, to solve such a complex distribution network reconfiguration model, if the traditional method is used to solve the distribution network reconfiguration model, only one high-quality solution can be obtained for each optimization. In this way, if the high-quality solution corresponds to the distribution network When the reconstruction scheme cannot meet the requirements of decision makers, the distribution network reconfiguration model needs to be optimized again until the high-quality solution obtained can meet the requirements of decision makers. Institutional efficiency can waste decision makers' time
