Similarity Calculation Considering the Impact of Voltage Regulation

Voltage curves similarity can be used to verify distribution network topology. However, the voltage curves may be affected by voltage regulation which will result in the inaccuracy of similarity calculation. A method which can be used to calculate the similarity of voltage curves when considering the impact of voltage regulation has been proposed in this paper. Kolmogorov-Smirnov test is used to detect the outliers between the voltage curves of two distribution transformer. Two case studies have been carried out to show the correctness of the method. Discussions have also been made. The results show that the method proposed in this paper will not be affected by voltage loss. The results also show that even if there are extreme outliers, whether the voltage curves of the two transformers are similar is still should be decided by the results of the subsections.
