A modified harmonic pricing scheme for customers based on quantifying the harmonic comprehensive contribution

Abstract

The growing application of various types of nonlinear loads aggravates the harmonic distortion in distribution networks. To effectively address the harmonic issues, implementing an incentive pricing mechanism is a feasible solution. In this paper, a modified scheme is proposed to achieve fair and reasonable harmonic pricing for every customer. The scheme uses a new quantitative index for determining the harmonic comprehensive contribution without any prior assumptions about harmonic impedance. By aggregating multiple time scales and harmonic orders, this new index outperforms the traditional index in representing the overall harmonic distortion responsibility. Moreover, the proposed scheme introduces the harmonic metering price and the harmonic penalty price, and it aims to rationally evaluate the costs of energy metering and harmonic mitigation. The efficacy of the proposed scheme is verified by computer simulation and field test. The simulation and experimental results demonstrate that the proposed scheme is better than the conventional scheme to provide a fairer harmonic price and encourage customers to reduce harmonic emissions.
