The power system of Suðuroy, Faroe Islands, is a hybrid power system with wind, photovoltaic (PV), hydro and thermal power. A battery system and synchronous condenser are to be installed in 2021. The study analyses the impact the currently installed inverter-based generation (IBG) has on the frequency and voltage fluctuations in the system. This is done by selecting a time period to analyse, validating dynamic simulations with measurements and then conducting simulations with and without the existing wind power and PV plant. The results show that with the current configuration the fluctuations in the IBG and the penetration of the IBG have a negative impact on the frequency fluctuations, and to some degree the voltage fluctuations. However, the wind power plant is currently not using its ability to contribute to smoothen frequency and voltage fluctuations, and this will be revised with the added battery system and synchronous condenser.
