Abstract:
This work describes the process of modelling the frequency response of the grid impedance in the range from zero hertz to several kilohertz from grid data in order to improve the current consideration of the grid impedance during the certifi-cation process of generation units. Several grid impedance measurements where performed and the resulting frequency responses are transferred with the help of grid data into a model of the specific connection point.
