An Efficient Zoning Method for Voltage Control in Distribution Networks Based on Sensitivity Coefficients

Abstract

Zoning method based on sensitivity coefficients is very efficient. But only reactive power injection is taken into account in most researches. It’s more reasonable to consider active and reactive power injection influences simultaneously. Then, AP clustering method is adopted to select the zones and critical buses in each zone. The results gained by AP method are more appropriate in comparison with the results obtained by hierarchical clustering approach.
