“…These new harmonic sources have comparable sizes and are distributed all over a network. Although they produce insignificant amount harmonic currents individually, the collective effect of a large number of such loads can be substantial [1][2][3][4][5][6]. Several power quality concerns have been identified due to such distributed harmonic sources [1][2][3][5][6][7][8][9].…”

The widespread adoption of energy efficient but harmonic-producing loads in residential homes has led to increased injection of harmonic currents into transmission systems. In response to this situation, a novel filtering scheme that can reduce the harmonic penetration into transmission systems is proposed. The scheme utilizes the tertiary winding of a substation transformer to construct a tuned low impedance path for the harmonic currents. The proposed scheme is capable of trapping two zero-sequence harmonics and three non-zero-sequence harmonics simultaneously. Design procedure has been developed. Performance of the scheme is evaluated and demonstrated through simulation studies. In addition, economic analysis reveals that the scheme is a cost-effective solution in comparison with other applicable methods.Index Terms-Power quality, harmonics, passive filter.  0885-8977 (c)

Summary An unprecedented growth of nonlinear load in recent decades has led to significant change in the power profile of modern distribution systems, which requires a modified approach for quantifying non‐sinusoidal power. Analysis of distribution system becomes even more challenging when voltage harmonics are also present in the substation bus besides nonlinear load. In this paper, a comprehensive distribution load flow algorithm for distorted and unbalanced radial distribution systems has been proposed. The methodology involves the computation of voltage and current distortion at each bus of the radial distribution system (RDS) to quantify various distortion power terms. Main contribution of the paper is to assess the increase in total power and overloading of shunt capacitors for various harmonic orders in the distorted distribution system. The proposed method has been tested on two IEEE distribution systems having current and voltage distortions.

Abstract:With the introduction of more non-linear loads, e.g., compact fluorescent lamps, electric vehicles, photovoltaics, etc., the need to determine the harmonic impact of the residential load is rising, illustrated by the many studies performed on their harmonic impact. Traditionally, these studies are performed for a single new device and single penetration level, neglecting the harmonic interaction between new types of devices, as well as giving little information at which moment in time possible problems may arise. A composite approach to access the impact of harmonic sources on the distribution network is therefore proposed. This method combines a bottom-up stochastic modeling of the residential load with harmonic measurement data and harmonic load-flows all based on a scenario analysis. The method is validated with measurement data and shows a good prediction of the current level of harmonics in a residential neighborhood for the current situation. To demonstrate the applicability of the proposed method, case studies are performed on the IEEE European Low Voltage Test Feeder. These case studies show a marked difference between applying individual device-based models and a composite modeling approach, demonstrating why the proposed approach is an adequate method for the determination of the impact of new devices on the harmonics.
