Combinatorial method for optimal sizing and placement of active power filters

Abstract

Combinatorial method for optimal sizing and placement of active power filters (APFs) has been presented in the paper. The main idea is to separate the sizing and placement parts of the algorithm to avoid calling the cost function during the APF sizing part of the algorithm, what allows to overcome some problems associated with nonlinearity and discontinuity of the APF cost function. The results confirm a high effectiveness of the method in comparison with the traditional approach. The main disadvantage of the method is a relatively large amount of computation caused by the combinatorial testing of all possible APF connection nodes.
