Embodiment Construction

[0061] The present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the protection scope of the present invention should not be limited thereby.

[0062] see first figure 1 , figure 1 It is a flow chart of the partition planning method of the AC / DC hybrid distribution network based on the parallel genetic algorithm of the present invention. It can be seen from the figure that the present invention first partitions the AC / DC hybrid distribution network to be planned through the partition method; The power grid planning method (mainly including substation planning and distributed power generation planning) establishes the planning model in the partition; finally, the parallel genetic algorithm is used to solve the planning model to obtain the final plan. Details below figure 1 process shown.

[0063] The first step: partition method of AC / DC hybrid distribution network.

Abstract

The invention provides an alternating current / direct current hybrid power distribution network partitioning and planning method based on a parallel genetic algorithm. The method comprises the steps of: 1) setting an alternating current / direct current hybrid power distribution network partitioning method; 2) setting an alternating current / direct current hybrid power distribution network planning method specifically including a transformer substation planning method and a distributed power supply planning method; 3) solving a planning theme by using a parallel genetic algorithm. The method can be used for planning solving for an alternating current / direct current hybrid power distribution network consisting of a flexible direct current device, an alternating current line, a direct current line, an alternating current load and a direct current load. The method effectively increases the planning precision, solves the problem that information interaction is impossible and makes results more reliable.

Description

technical field [0001] The invention relates to optimal planning of an AC / DC hybrid distribution network, in particular to a partition planning method for an AC / DC hybrid distribution network based on a parallel genetic algorithm. Background technique [0002] Distribution network planning is an important part of distribution network construction. Urban distribution network has high requirements for reliability, power supply capacity and economy. A good grid structure plays an important role in improving reliability, power supply capacity and economy. to the key role. The traditional distribution network planning method has become increasingly mature. With the development of DC source, load and flexible DC technology, the AC-DC hybrid distribution network has shown greater advantages in terms of technology and economy, and is an important development of the future distribution network. direction. [0003] After nearly ten years of rapid development, the scale of my country...
