Aggregated modelling of distributed networks with distributed generation

A new methodology to derive an aggregated model representation of a distributed network with distributed generation (DG) is presented. The network includes small-scale wind turbines based on induction generators, distribution lines, transformers, reactive power compensation devices, such as capacitors, and low voltage feeders. This aggregated model is employed to analyse induction generators starting up currents and short circuit fault currents. The study is conducted in Matlab/Simulink and simulation results that illustrate the adequacy of the proposed methodology are presented and discussed.
