Techno-economic optimisation of the mix of power system flexibility solutions

Abstract : In our attempt to mitigate climate change, fossil fuel based power generation is gradually being replaced by low-carbon technologies, primarily wind and solar. This is simultaneously increasing the need for power system flexibility and removing our historically dominant way of providing it. A key question to be addressed is hence that of the optimal combination of flexibility solutions able to operate a power system with high penetrations of variable renewables. In this PhD, we propose new metrics quantifying different facets of flexibility, improving our understanding and ability to communicate policy recommendations to wider audiences. We then concentrate on the improvement of the representation of flexibility in power system planning, through the bi-directional soft-linking of two different model types, the capacity expansion model OSeMOSYS and the production cost model Antares.
