摘要
制定科学合理的黑启动方案对于实现电网全停后的快速恢复意义重大。本文提出了一种基于模糊区间数的黑启动方案评估层次分析法。首先介绍了层次分析法评估的一般步骤;然后针对此方法的不足引入模糊区间数,介绍了区间数判断矩阵和区间数可能度排序,最后给出了基于模糊区间数的层次分析法评估步骤。针对某实际电网的黑启动案例证明了该方法将为黑启动恢复提供更全面、准确的决策参考。
Rational black-start plans are necessary for restoring the power system as soon as possible. A novel method for assessing black-start plans, namely fuzzy interval number based hierarchical analysis is proposed in this paper. First, the basic steps of hierarchical analysis process are introduced according to influencing factors to black-start plans. Secondly, considering the shortcomings of AHP, fuzzy interval number is introduced, which can be used to establish judgment matrix and to assign priority. Finally, the basic steps of this novel method are given. It is proved from an application of an actual power system that the method can provide dispatchers with more comprehensive and exact decision-making references.
