潮流建模中的不确定性——边界潮流法的应用(英文)

Uncertainty in Load Flow Modeling——Application of the Boundary Load Flow

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。

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.
