Evaluating the Responsibility of Harmonic Distortion in Single-Phase Systems with Pricing Strategy

Presently, distribution companies are concerned with the penalty applications in energy tariff to control harmonic distortion levels in distribution systems. It's common to consider this for industrial and commercial customers. But, nowadays the usage of modern electronic equipment in residential section is increasing and people are going to do their jobs at home, which mean more distortion in single phase systems. So, in the early future companies will pay more attention for requesting residential customers to provide better power quality. This paper proposes a distinct rate structure to regulate the harmonic distortion in single phase systems, which is applicable for residential loads. The idea is to evaluate the responsibility of harmonic distortion at the Point of Common Coupling (PCC) between utility and customer for each harmonic order of power frequency. By finding the utility and customer harmonic contributions, it is possible to achieve fairer cost sharing through the proposed rate structure. This method has been verified through a simplified case study mentioned in the IEEE Std. 1459-2000.
