The goal is to minimize the cost of the filters, the filters loss, and the total harmonic distortion of currents and voltages at each bus, simultaneously.
The objective is to minimize the cost of the filter, the filters loss, the total harmonic distortion of currents and voltages at each bus simultaneously.
A simultaneous operation of a group of PCs causes the distortion of the current waveform and negatively affects the supply of voltage.
Power quality is a relevant aspect in power distribution systems, which among others, considers service continuity and distortion of the current and voltage waveforms.
The presented method is proved through experimental investigation, where experimental results show that the THD (total harmonic distortion) of grid current is about 3% under 12.25% THD of the grid voltage.
Greg Archer, Transport & Environment's vehicle programme manager, told the BBC: "There is a need for a new [emissions] test but what we're also seeing here is a distortion of the current system.
With the decreasing distortion of the current flowing to the main bus, the voltage quality of sub buses will be improved, and the burden of the harmonic compensation devices installed at the main bus can be relieved.
The total harmonic distortion of the current injected to the utility grid from the multi-bus microgrid can be expressed as: THD_{i} = frac{{sqrt {sumlimits_{h = 2}^{n} {I_{{Gh}^{2}} } } }}{{I_{G 1} }} times 100% (4 where I G1 and I Gh are the rms values of the fundamental and h th harmonic components of the current injected to the utility grid, respectively.
The objective is to minimize the cost of the filter, the total demand distortion of harmonic currents and the total harmonic distortion of voltages at each bus simultaneously.
The objective is to minimize the total demand distortion of harmonic currents, total harmonic distortion of load bus voltages, filters loss and the cost of total installation of LC tuned filters.
