“…A number of articles [32,33] have proposed representing nonlinear loads on the basis of time-domain [34,35], harmonic domain [36] or frequency domain models [37]. According to the frequency-domain model approach, a power converter may be analyzed by observing the converter passing through a sequence of states describing its conduction pattern.…”

The paper deals with issues of modeling nonlinear electrical loads of various types, such an uncontrolled rectifier, thyristor rectifier, thyristor power regulator and mixed equivalent nonlinear load. For these load types, existing analytical expressions were identified to determine the magnitudes of harmonic currents, and waveforms of currents were obtained during measurements in laboratory conditions with variable parameters of the grid impedance and load. The obtained results were compared, and it was found that the error in determining the magnitudes of harmonic currents can reach 60% for an individual load and 54% for an equivalent load. A more accurate method for determining the parameters of nonlinear electrical load is also proposed, which is based on the application of shunt harmonic filters. In laboratory conditions, it was found that when using the developed method, the error did not exceed 10% for an individual load and 14% for an equivalent load.

“…Nevertheless, some downsides arise and, among others, the increase of voltage and current distortion generated by the nonlinearity of these devices which may constitute a problem when excessively high. Some examples of new harmonic sources which can be found in the distribution grid and whose penetration can be expected to increase are: compact fluorescent lamps (CFLs) [1], light-emitting diode (LED) lamps, distributed photovoltaic (PV) systems [2], adjustablespeed-drive-based home appliances and electric vehicle (EV) chargers [3], [4].…”

with the advent of power electronics, the application of solid-state electronics for the control and conversion of electric power is substantially increasing at the expenses of simple rotating machines and linear loads. This leads to power quality problems due to the sinewave distortion of current and voltage caused by such power-electronics-based equipment. Consequently, the investigation and understanding of harmonic emissions caused by those devices become of major importance in order to assure a continuous and reliable operation of the electrical distribution grid. The following paper aims to investigate the harmonic issues in distribution grids, due to power electronic devices with particular focus on electric vehicle chargers.
