Abstract

Expected bulk connection of renewable energy sources to existing distribution networks may change dynamic properties of power systems and increase the size of power system models used for the analysis of power system operation and stability problems. To reduce the size and complexity of modelling, distribution networks could be replaced by their dynamic equivalents. This paper focuses on identification of dynamic equivalents of distribution network from measured disturbance data. The validity of derived state-space models has been confirmed by simulation.
