Adaptive Robust Optimization for European Electricity System Planning Considering Regional Dunkelflaute Events
This study employs an adaptive robust optimization framework to demonstrate that incorporating worst-case regional "Dunkelflaute" events into European electricity planning reveals nonlinear cost increases and a shift toward long-duration hydrogen storage and load shedding as event severity grows, highlighting the critical need for coordinated cross-border infrastructure and geographically balanced renewable deployment to ensure system resilience.
