摘要

在电网负荷注入水平和增长方式都不确定的情况下，给出了一种新的以区间形式表示的电压稳定评价模型。该模型不仅能处理变量的区间特性，还可以计及其概率分布，为不确定方式下的电压稳定性分析提供了一种新思路。然后采用线性规划法对模型进行求解，解决了双端不固定条件下的最短路径问题。最后在IEEE 30节点系统中验证了所提出的算法的快速有效性。

Abstract

Under the condition that load and its increasing pattern is uncertain， a novel voltage stability evaluation model withinterval expression is given. This model can tackle the interval characteristics of the variables and can consider the probabilitydistribution of these variables. The proposed approach provides a new light for static voltage stability evaluation underuncertain conditions. Linear programming is employed to solve this shortest path problem with two terminals being not fixed.At last， the speed and efficiency of the proposed method are tested on IEEE 30-bus power system.
