A Comparative Analysis between Methodologies for Responsibility Assignment on Harmonic Distortions

A current challenge which emanates from the Power Quality area is the search for a reliable means for sharing the responsibility assignment on harmonic distortions between the parties involved. In fact, to determine the THD (Total Harmonic Distortion) levels for the points of coupling between the suppliers and consumers, the identification of the individual contributions of the parties is presented as information relevant to any mitigating measures. In this context, although in literature there have been some highlighted methodologies, which aim at characterizing portions of responsibility between the agents, due to the subjects concerning the procedures, there are still frequent questionnaires concerning the conclusive contribution from the parties. Thus, this article summarizes the main procedures found in literature and through the implementation of a hypothetical test system that operates under three distinct conditions, a set of performance computational studies are carried out. The studies yield results that are utilized as a comparative and critical base of the methodologies being directed towards the motives described herein, while highlighting their potential along with limitations.
