Predicting conducted emissions of multiple VSCs using dimension reduction technique

Abstract

Operational uncertainties such as variation of power or grid impedance affect the level of conducted emission of power converters in renewable energy systems. This paper utilizes an enhanced Unscented Transform (UT) method based on dimension reduction technique to predict the conducted emissions of multiple Voltage Source Converters (VSCs) in the presence of uncertainties. The accuracy of the predicted results are then compared with the Monte Carlo Simulation approach and the traditional Unscented Transform.
