Embodiment 1

[0062] A design method of distribution network planning and construction scheme based on non-dominated sorting genetic algorithm, including the following specific steps:

[0063] S1: generation of planning items;

[0064] With the substation as the core, sort out the status quo and the target network respectively, compare the two to get the difference between the target grid and the current grid, and then analyze the difference according to the grid structure comparison, and automatically generate according to a certain project division principle Library of planning projects from current grid to target grid;

[0065] The basic comparison unit of the comparative analysis of the two power grids is each equipment element in the network. For each device included in the current grid, it is first searched in the device list of the target grid, and further parameter comparisons are performed on the searched components. If the device component is an AC line, the parameters to be comp...

Abstract

The present invention discloses a design method of the distribution network planning and construction scheme based on the non-dominated sorting genetic algorithm. The method comprises: generating a planning project and carrying out automatic optimization design of the project construction timing; with the new computer technology, sorting out the current situation and the target grid, comparing the current situation with the target grid to obtain the difference between the target grid and the current grid, and based on the difference obtained by comparing and analyzing the grid, automatically generating a planning project library from the current grid to the target grid according to a certain project division principle; using the distribution network construction timing scheme based on the non-dominated sorting genetic algorithm to carry out optimization, and finishing adaptive search of the optimal solution to the problem by imitating the selection, crossover and mutation mechanism in the process of biological evolution, so that parallelism of robustness and implicity are ensured, and the method is more unique and superior than other traditional optimization algorithms. The method disclosed by the present invention satisfies the technical requirements such as safety, reliability, and the like, and ensures the rationality of the intermediate grid and the economy of construction and operation.

Description

technical field [0001] The invention relates to the field of distribution network planning, and more specifically, relates to a method for designing a distribution network planning and construction scheme based on a non-dominated sorting genetic algorithm. Background technique [0002] The urban power grid is an important part of the power system, the main load center of the power system, and an important infrastructure for urban modernization. Urban grid planning is not only an important part of power system planning, but also an important part of urban planning. Reasonable urban grid planning is a prerequisite for realizing the economy and security of future urban grids, and can obtain great economic and social benefits. [0003] When planning urban power grids, for areas with more mature development, the focus of planning is to solve the problems in the current power grid based on the analysis of the current power grid. Therefore, it should be based on the severity of the...
