Power harmonic and interharmonic detection method in renewable power based on Nuttall double-window all-phase FFT algorithm

Harmonics and interharmonics adversely affect power grids. The fast Fourier transform (FFT) algorithm is one of the most commonly used methods for harmonic analysis. However, in practical applications, the accuracy of harmonic analysis can be seriously affected by fence effect and spectral leakage,...
