Harmonic Control in Power Systems by means of Harmonic Pricing

Increasing harmonic contamination is one of the concerns in power systems that has been more considered. On the other hand, the high cost of compensation can eliminate the possibility of compensation across the network. Regarding the restructuring of power systems, it has been possible to provide the compensation cost by contaminating subscribers. In this paper, a new method for control the network harmonic is presented using harmonic pricing. The base of pricing in this method is to determine the fair harmonic contribution in the point of common coupling voltage. In addition, a new index has been proposed to determine the harmonic contribution of the customer and utility to the harmonic contamination of the point of common coupling. By using this index, an accurate impression of the customer and utility contribution in all of the dominant harmonic levels is obtained. The simulation results on the IEEE 14-bus standard network illustrate the effectiveness of the proposed method for pricing based on fair contribution of customer and network. Also, the results show that by justly determining the harmonic contribution, the customer can be encouraged to reduce or control the harmonic. Otherwise, by sum of the penalty fees, harmonic filters can be installed at the desired location and can be applied to the harmonic control.
