Data-Based Harmonic Impact Quantification of Multiple Loads In A Real Medium-Voltage Network

This paper analyses a method to quantify harmonic contribution of multiple loads in a real medium-voltage network. The basis of this work is the Harmonic Impact Index, that can be developed with a data-driven approach and is a suitable method to determine the harmonic contribution of more than two parties. Background harmonics from the overlaying grid have a negative impact on the accuracy of the method and can be considered a source of error. In this paper, a short introduction in Partial Least Squares regression is given and crucial points of the implementation are presented. Finally, a possible improvement of the Harmonic Impact Index estimation is provided. Incorporating synchronized phasor measurements has shown to improve the prediction accuracy of the regression model.
