Abstract

This paper presents a new method to compute dynamic equivalents of active distribution grids. The method is based on the identification of dominant electromechanical modes of oscillations by using the instantaneous Euclidean distance in polar coordinates in a benchmark distribution grid. The method aims to preserve the dominant electromechanical modes in a dynamic equivalent model. A model parameter identification technique is used to compute the parameters of equivalent generators.
