Embodiment Construction

[0052] Embodiments of the present invention are described in further detail below in conjunction with the accompanying drawings:

[0053] A hierarchical and partitioned distribution network frame planning method, comprising the following steps:

[0054] Step 1: Divide the entire urban distribution grid structure into partitions; calculate the power supply capacity of the grid in the planned area according to the linear programming method; establish a joint optimized two-layer multi-objective joint planning model with the help of the idea of ​​hierarchical planning; Two-level multi-objective programming problems are transformed and analyzed.

[0055] From the perspective of mathematical modeling, urban distribution grid planning is a multi-objective combinatorial optimization problem, and the solution process is relatively cumbersome; Effective processing can make planning modeling closer to actual problems. In addition, the urban power grid planning needs to fully consider t...

Abstract

The invention relates to a layered and partitioned power distribution network frame programming method, which is characterized by comprising the steps of partitioning the whole urban power distribution network gird structure; calculating the power supply capacity of a power grid of a programmed area according to a linear programming method; establishing a two-level multi-objective joint programming model for joint optimization by the aid of an idea of layered programming; transforming and analyzing a two-level multi-objective programming problem; carrying out joint coding on the grid structure and the partitioning mode by adopting a joint coding mode; and processing codes by adopting a two-level multi-objective genetic algorithm according to joint coding so as to acquire a programming operation result. Provided by the invention is a joint programming optimization method based on combination of the two-level multi-objective optimization generic algorithm based grid structure and the partitioning mode, thereby being capable of improving the rationality of power grid programming optimization to a certain degree. Meanwhile, the existing grid frame is sufficiently utilized, thereby saving the construction cost, and enabling the new grid frame to not only meet power supply requirements but also have high economy.

Description

technical field [0001] The invention belongs to the technical field of power supply and distribution, and in particular relates to a hierarchical and partitioned distribution network frame planning method. Background technique [0002] With the continuous development of my country's economic level and the continuous improvement of technological innovation, a large number of industrial parks and innovation demonstration parks that stimulate the economic growth of their regions have been established and developed rapidly across the country. A large number of companies, institutions, manufacturers, and scientific research institutes It has successively entered emerging industrial parks in various regions, and its diversified demand for power supply has prompted a new round of planning, reconstruction and expansion of the grid grid in the area where the park is located to meet the increasing and higher power supply level requirements. [0003] In recent years, with the continuous...
