基于改进模拟植物生长算法的配电网重构

Power Distribution Network Reconstruction Based on Improved Plant Growth Simulation Algorithm

针对基本模拟植物生长算法的不足,在生长点集规模方面对其进行了改进。将改进模拟植物生长算法应用于配电网络重构,该算法以网损最小为目标函数,以各个基本环路作为控制变量,采用断开、闭合、联闭和长闭4种状态描述开关的运行方式,减小了寻优的搜索范围,提高了计算效率。分析IEEE16节点和IEEE33节点2个不同规模测试系统,与相关文献结果进行对比,表明该方法在解决配电网络重构问题上具有很高的搜索效率和寻优性能。

Aiming at insufficiency of basic simulation of plant growth algorithm, this paper improved the growth point integration scale, applying the improved plant growth simulation algorithm in power distribution network reconstruction. This algorithm took minimum network loss as target functions, each basic loop as control variable, and adopted breaking-off, closing, union closing and long closing 4 states to describe operation modes of switch, so as to reduce the range of optimization searching, raising calculation ef- ficiency. Analysis was made to IEEE16 node and IEEE33 node two different scale test systems. The results of comparison with related documents show that the method is with very high efficiency and optimization searching performance in solution of power distribution network reconstruction issue.
