Abstract-A new method is proposed in this paper to determine the harmonic contributions of a customer at the point of common coupling. The method can quantify customer and utility responsibilities for limit violations caused by either harmonic source changes or harmonic impedance changes. It can be implemented in current power quality monitors and digital revenue meters. The method makes it possible to develop fair and consistent billing schemes for harmonic distortion control.Index Terms-Harmonics, harmonic direction, harmonic impedance and power quality.

“…S N is an important quantity because it can be a reasonable indication of harmonic pollution; thus, it can be useful for introducing harmonic penalties or incentives if it is included in rate structures. This harmonic pollution assessment was intensely discussed in [8][9][10]. However, the frequency-dependent losses of the equipment were not explicitly addressed.…”

Power systems suffer from harmonic distortion and extra ohmic losses associated with them. Moreover, all harmonic frequencies are mostly assumed to have the same effect on the system losses. However, the frequency-dependency of the resistances should be taken into account, so that the apparent power and the power factor have to considerably reflect power losses under non-sinusoidal conditions. In this study, the difference between unweighted and weighted non-sinusoidal losses is addressed. A new harmonic-adjusted total harmonic distortion (THD) definition is proposed for both voltage and current. Besides, a new formula that relates the proposed harmonic-adjusted THD and a generalised harmonic derating factor definition of the frequency-dependent losses of the power transmission and distribution equipment is derived. An optimal C-type passive filter design for harmonic mitigation and power factor correction based on the minimisation of the proposed harmonic-adjusted THD for a balanced non-sinusoidal system is introduced. A comparative study of the proposed filter design based on the new harmonic-adjusted definition, and a conventional filter design based on standard THD definition, is presented.
