RfG NC Compliance Simulations Utilizing Real Time Simulator

Integrating renewable energy sources, especially those based on power electronic converter systems, is currently one of the critical areas of research in power systems. The dynamic development of this source type puts modern power systems under significant technical pressure because their method of operation is significantly different from conventional units. However, the principles of operation of power systems, including legal ones, were developed based on the conventional ones. In response to these changes, the European Commission introduced grid codes that are intended to standardize the requirements for new generating units. The article presents the basic arrangements resulting from the RfG NC Grid Code. The ability of the real-time simulator to conduct compliance simulations within the selected scope of the Grid Code was verified. For this purpose, a laboratory system was built taking into account actual relays, and a D-type wind farm was modelled, based on an actual facility in Poland.
