Cost/benefit analysis of transmission grid expansion to enable further integration of renewable electricity generation in Austria

摘要: This paper elaborates on the costs and benefits of expanding Austrian transmission system implementation innovative grid-impacting technologies (e.g. flexible AC systems (FACTS), dynamic line rating (DLR)) to support further integration renewable energy sources for electricity generation (RES-E). Therefore, a fundamental market model has been developed - respecting DC load flows applied analysing different future scenarios, notably time horizon 2020, 2030 2050. Up 2020 2030, special focus is put finalisation so-called “380 kV-level ring” in Austria enable enhanced RES-E integration. The results confirm that power expansion states Salzburg Carinthia important connect imports from Germany with pumped hydro storage capacities, one hand, wind farms east storages western part Austria, other hand. For 2050, indicate FACTS DLR can reduce curtailment significantly.
