在配电网无功补偿优化过程中,Tabu Search算法能够高效地将最优解搜索出来,因此,将Tabu Search算法应用于配电网无功补偿优化具有现实可操作性。本文对Tabu Search方法的原理进行了详细介绍,因为农村配电网线路具备很多特点,综合考量其并联电容器投切等问题及特点,本文在Tabu Search的基础上,进行了一系列改进,用来解决配电网的投切优化问题。提出了基于电容器投切分组的二进制编码优化,基于无功补偿的损耗降低特点,根据功率传输方向,对权重根据由低到高的顺序排列,然后进行二进制编码,从二进制编码串的末端进行移动;Tabu Search非常依赖于初始解,提出了当前时段处于运行退出状态时,根据无功缺额电容器的配置方式进行。

In the process of reactive power compensation optimization of distribution network,Tabu Search algorithm can efficiently Search out the optimal solution.Therefore,it has practical operability to apply Tabu Search algorithm to reactive power compensation optimization of distribution network.In this paper,the principle of Tabu Search method is introduced in detail.Because rural distribution network lines have many characteristics,problems and characteristics such as shunt capacitor switching and cutting are comprehensively considered.Based on Tabu Search,a series of improvements are made in this paper to solve the switching and cutting optimization problem of distribution network.This paper presents a binary coding optimization based on capacitor switching and switching grouping.Based on the characteristics of reactive power compensation loss reduction,the weights are arranged from low to high according to the direction of power transmission,and then the binary coding is carried out to move from the end of the binary coding string.Tabu Search is very dependent on the initial solution,and proposes that when the current period is in the run-out state,it should be configured according to the reactive power gap capacitor.
