This paper presents a fast computation method of static voltage stability using geometric parameter adjustment for the continuation power flow. The conventional method has the following problems: voltage stability assessment (VSA) is high accuracy but there is much total convergence calculation number of times. The features of the proposed method are following: (1) to change the step size of a geometric parameter in prediction part, (2) to adjust a geometric parameter using temporary maximum loading point (MLP) by Look‐Ahead method. The proposed method has an advantage of being able to maintain high accuracy for VSA and to calculate less total convergence calculation number of times than conventional methods in IEEE test case of 118 and 300 bus systems.

基于几何参数调整的连续潮流快速计算静态电压稳定性的方法

本文提出了一种通过几何参数调整连续功率流的静态电压稳定性的快速计算方法。传统方法存在以下问题：电压稳定性评估（VSA）精度高，但总收敛计算次数却很多。该方法的特点如下：（1）更改预测部分中几何参数的步长；（2）使用临时最大加载点（MLP）通过Look-Ahead方法调整几何参数。与在118和300总线系统的IEEE测试案例中的常规方法相比，所提出的方法的优点是能够保持VSA的高精度并计算较少的总收敛计算次数。
