The excessive waveform distortions in the present power distribution systems are produced mainly by the large number of residential loads. Such distributed sources of harmonics cannot be easily treated by the traditional mitigation methods, which have been commonly applied for concentrated and easily detectable industrial distorting loads. This thesis presents new harmonic mitigation techniques necessary for managing this new situation. The proposed strategies are supported by several analytical and simulation studies. Different options for both active and passive centralized and distributed filters are investigated and compared to determine their different technical and economic aspects. Overall, the results of extensive studies confirm that the novel zero-sequence harmonic filter and the new scheme of the low-voltage distributed active filters introduced in this thesis are promising solutions for the increasing harmonic problems in residential feeders.
