Dynamic load modelling using measured data in distribution networks

Abstract

Induction motor loads are considered as the main dynamic load in distribution networks. The aim of this paper is to propose a method to identify and model induction motor loads based on the data from Phasor Measurement Point (PMU). In this method, the active power-voltage transfer function is extracted from PMUs data, and the location of zero and pole of this transfer function can be employed to identify and model the induction motor loads. The effectiveness of the proposed method is evaluated by simulation results.
