预防性安全约束最优潮流的主导故障过滤技术

Dominant Contingence Filtering Techniques for Preventive Security-Constrained Optimal Power Flow

运用适当的故障过滤方法筛选有效的预想故障,可以提高预防性的静态安全约束最优潮流的计算效率。提出一种新的应用于预防性静态安全约束最优潮流的故障过滤方法,该方法根据故障引起的约束条件越限的程度,将故障区分为主导故障和非主导故障两类。迭代过程中,只将主导故障引入到安全约束最优潮流中计算,经过几次迭代即可求出结果。在IEEE-4、IEEE-14和IEEE-30节点系统上测试本文过滤技术,测试结果表明:应用主导故障过滤技术减小了每次计算的安全约束最优潮流的规模,有效的提高了预防性静态安全约束最优潮流的计算效率。

The application of the appropriate contingence filtering improve the calculation efficiency of preventive security constrained tingence filtering method for preventive security constrained optimal methods to filter the non-dminant contingencies can optimal power flow. This paper proposes a new con- power flow. According to the more limited extent, this method classified as dominant contingengce and non-dominant contingengce. Only need considerate the dominant contin- gence in the preventive security constrained optimal power flow. Comparisons of the implementations of the proposed method and a general filtering methods on IEEE-4, IEEE-14, IEEE-30 bus systems are presented. It is shown that the proposed method is valid and efficient.
