Abstract
Due to the shift in electrical energy generation from thermal synchronous generators towards various renewable sources, power system stability will become a more pressing issue in the near future. In this thesis, we explore possible improvements to the dynamic grid model currently used by TenneT TSO for large-disturbance stability studies, specifically the addition of motor load, wind, solar PV and HVDC transmission modelling. Thus we pave the way for future, more in-depth research that can contribute to the development of a more sophisticated dynamic grid model for operational and planning use. Our results indicate that motor load modelling has a strong negative influence on grid dynamic performance (compared to a static representation of the same load), and that wind and PV models have a strong positive influence, but that particularly for wind models, the choice of appropriate model parameters remains a challenge.
