Modelling and prediction of current harmonics generated by power converters in distribution networks
IET Generation, Transmission & Distribution, 2021 Predicting current harmonics in distribution networks is essential to find harmonic losses and power quality indices. In order to predict the current harmonics, the effect of grid impedance and voltage distortions on grid‐connected power converters need ...
