摘要
探讨了一种静态电压多指标综合评判方法。该方法基于电压有功灵敏度、无功裕度、节点电压变化三个电压指标,以客观赋值与主观赋值组合方法对上述三个指标分别赋予不同权重求得综合指标以辨识系统各节点薄弱程度。最后以IEEE39节点系统为仿真对象进行分析,以单一指标与综合指标分别辨识系统薄弱母线,验证该综合评判方法的有效性与科学性。
This paper develops a static voltage multi-criteria comprehensive evaluation.This evaluation base on three voltage index that voltage active-power sensitivity index、reactive margin index and the change of node voltage index,use the method that compose both objective competent and assignment assignment to put the three voltage index different weights obtain integrated index,distinguish the degree for node voltage of system.Then analysis of simulation object base on IEEE39 node system,use single index and integrated index distinguishweak bus of systems, the rationality and effectiveness of the comprehensive evaluation.
