Abstract

Due to importance of harmonic analysis in interconnected network. In this paper, a method is proposed that could be determined the main responsible of the harmonic pollution of the desired bus voltage or the current desired line in interconnected networks. In this paper, the defects of using the "vector projection" method are presented to solve the above problem; so, a method is proposed based on reducing the amplitude of the harmonic voltage and current due to the reduction of the harmonic amplitude.  Both methods are evaluated in a 6-buses IEEE grid using Digsilent and MATLAB software at a specific harmonic frequency. The results of the evaluation of the two methods indicate that the method of "vector projection" is not necessarily the correct answer if the number of harmonic sources is more than two sources; consequently. However, the results of the proposed method are highly rational in the interconnected grids.
