Enhancement of the current quality using efficient extraction and mitigation processes

This paper introduces an innovative compensation strategy to extract and mitigate different current disturbances such as the current harmonics, cyclic current fluctuation and random current fluctuation. The contribution in this paper is that it does not need any mathematical model to represent the current disturbances and consequently extract these disturbances like the other common and utilized techniques. The proposed technique is simple for formulation and practical for implementation compared to the state-estimation techniques used for the same applications. The proposed strategy depends on recursive formulation of the Wiener filter. The presented ideas in this paper are proved by digital simulation results using MATLAB/SIMULINK on the aforementioned current problems in the distribution systems.
