Increased resilience in the future power system with high share of power electronics

The energy transition and electrification lead to new challenges to ensure a secure and resilient electricity supply in Sweden. Consumption (e.g. electric cars, electrolysers) and production (e.g. wind/solar) will increasingly be controlled through power electronics which have different technical properties compared to the synchronous generator. Hence, the need for digitization and control increases.

This project aims to investigate how changes in the characteristics of the power system, e.g. less inertia, short-circuit power and increased voltage sensitivity affect the resilience of the future and to improve it through new control methods (voltage control, short circuit current injection, grid forming). The goal is to

- increase knowledge in the industry of how resilience is affected by the energy transition - develop key performance indicators for the robustness of the system (resilience) - develop control schemes of inverters for increased resilience in the different system state
