Interharmonics: Theory and Modeling
Some of the most remarkable issues related to interharmonic theory and modeling are presented. Starting from the basic definitions and concepts, attention is first devoted to interharmonic sources. Then, the interharmonic assessment is considered with particular attention to the problem of the frequency resolution and of the computational burden ...

Interharmonic Analysis Model of Photovoltaic Grid-connected System with Extended Dynamic Phasors
The interactions between randomly fluctuating power outputs from photovoltaic (PV) at the DC side and background voltage distortions at the AC side could generate interharmonics in the PV grid-connected system (PVGS).

Development of interharmonics identification using enhanced-FFT algorithm
The fast Fourier transform (FFT) is a mostly used tool to measure power system harmonics. FFT, however, is not applicable to analyse interharmonics due to spectral leakage effect.

Power measurement accuracy analysis in the presence of interharmonics [PDF]
Abstract Interharmonics present in voltage/current signals affect the measurement accuracy of power quantities defined in standard IEEE 1459. In this paper, the measurement errors caused by the measurement time intervals not satisfying integral multiple periods of interharmonics are discussed.
