Abstract :
In this paper, a new method for identification of dominant source in creation of current and voltage distortions in PCC bus is presented. In proposed method, using superposition method along with definition of harmonic contribution and combining them with the critical impedance algorithm, new indices are defined and novel algorithm is presented. In this algorithm contrary to the critical impedance method, there is no need for values of customer's harmonic impedances. Also there is no probability that proposed algorithm lead to incorrect identification of dominant source even in cases in which the shares of PCC sides are close to each other. This fact is shown by comparison between proposed algorithm and critical impedance method. The analysis is verified on IEEE 13-bus test system using DigSilent software.
