| 摘 要： | 回顾了边界潮流法最新研究进展和应用现状.边界潮流法是一种通过赋予不确定节点功率以模糊/区间数来找到精确潮流解的方法.边界潮流法得到的结果可以纳入系统不充裕指标的形式中.这些指标可用于风险评估--决策过程中的基本部分.118节点测试系统的数字仿真结果表明了所提方法的适用性.

| Abstract: | This paper presents a review of the recent developments in boundary load flow (BLF)and its application. The BLF is a method that finds accurate load flow solutions when uncertain nodal powers are given as fuzzy/interval numbers. The results obtained from the BLF can be aggregated in a form of system inadequacy indices. Such indices are to be used in risk assessment, an essential part of the decision-making process. Numerical results from IEEE 118-bus test system are presented to show the feasibility of the approach. |
