TL;DR: In this paper, the most remarkable issues related to interharmonic theory and modeling are presented, starting from the basic definitions and concepts, attention is first devoted to inter-harmonic sources, and then the interharmonics assessment is considered with particular attention to the problem of the frequency resolution and of the computational burden associated with the analysis of periodic steady-state waveforms.

TL;DR: In this article, the spectral leakage problems due to synchronization errors of the analyzed waveforms with the window widths adopted are analyzed and improvements of the signal processing recommended by the IEC, based on the utilization of the classical Hanning window in place of the rectangular window, are proposed and made compatible with the grouping technique introduced in the standards.

TL;DR: In this article, a wind power forecasting method based on the use of discrete time Markov chain models is developed starting from real wind power time series data, which allows to directly obtain in an easy way an estimate of the wind power distributions on a very short-term horizon, without requiring restrictive assumptions on wind power probability distribution.

TL;DR: A new desynchronized processing technique for harmonic and interharmonic analysis that has general validity and results fully compatible with the IEC standard is presented and is as accurate as those of synchronized techniques.
