Consequently, grid-forming inverters are needed to ensure the system stability of the future grid. In the joint research project "VerbundnetzStabil", conducted by Fraunhofer ISE and its partners, the stability of a grid system with a high penetration of inverter-based renewable energy sources (RES) is investigated. This master thesis aims to analyze the response of the inverter simulation model, designed by Fraunhofer ISE, facing different events, whether it reacts as a synchronous machine and helps to maintain the stability in the network, and at the same time analyze the cross-coupling effect between the active and reactive power of the controller. For this purpose, the test models were designed in DIgSILENT PowerFactory to get RMS and EMT results. The results were compared with experimental results obtained in the multimegawatt Lab from Fraunhofer ISE to improve the inverter response.
