21. New power quality indices / Leonowicz, Z ; [RZ I07/2007/I-024] [ENY-ARTICLE-2008-171]
The author shows that the use of high-resolution spectrum estimation methods instead of Fourier-based techniques can improve the accuracy of measurement of spectral parameters of distorted waveforms encountered in power systems, in particular the estimation of the power quality indices (such as inter/harmonic groups and subgroups). [...]

22. Wind Power Generation-related Power Quality Issues / Lu, Y [ENY-ARTICLE-2008-144]
As a promising renewable alternative, the wind power is highly expected to contribute a significant part of generation in power systems in the future, but this also bring new integration related power quality issues, which mainly consist of power flow fluctuation analyzed with current, voltage fluctuation and flicker severity factor (P lt and P st ) as ‘ case study ’ , by its comparatively new characteristics, due to the fluctuation nature of the wind (velocity) and the comparatively new type of its generators (currently popular type of squirrel-cage induction). [...]
