Which wind and solar modelling choices matter? Effects on capacity factors, energy droughts and European power system configuration
L. Karkossa, A. Grochowicz, M. J. Koivisto +2
Europe's future power system will rely heavily on wind and solar power and must remain resilient during prolonged periods of low wind and solar generation, known as variable renewa…
Resilience metrics to guide back-up investments in the power system during extreme weather
Aleksander Grochowicz, Hannah C. Bloomfield, Marta Victoria
Security of supply is a common and important concern when integrating renewables in net-zero power systems. Extreme weather affects both demand and supply leading to power system s…
Exploring near-optimal energy systems with stakeholders: a novel approach for participatory modelling
Oskar Vågerö, Koen van Greevenbroek, Aleksander Grochowicz +1
Involving people in energy systems planning can increase the legitimacy and socio-political feasibility of energy transitions. Participatory research in energy modelling offers the…
Balancing Act: The Cost of Wind Restrictions in Norway's Electricity Transition
Maximilian Roithner, Paola Velasco Herrejon, Koen van Greevenbroek +5
To meet its commitments under the Paris Agreement and reduce its dependency on energy imports, the pace, and scale of renewable energy deployment across Europe must increase dramat…
Trading off regional and overall energy system design flexibility in the net-zero transition
Koen van Greevenbroek, Aleksander Grochowicz, Marianne Zeyringer +1
The transition to net-zero emissions in Europe is determined by a patchwork of country-level and EU-wide policy, creating coordination challenges in an interconnected system. We us…
Using power system modelling outputs to identify weather-induced extreme events in highly renewable systems
Aleksander Grochowicz, Koen van Greevenbroek, Hannah C. Bloomfield
In highly renewable power systems the increased weather dependence can result in new resilience challenges, such as renewable energy droughts, or a lack of sufficient renewable gen…
Spatio-temporal smoothing and dynamics of different electricity flexibility options for highly renewable energy systems -- Case study for Norway
Aleksander Grochowicz, Fred Espen Benth, Marianne Zeyringer
In this article, we investigate mismatch of renewable electricity production to demand and how this is affected by flexibility options on the supply side. We assess the impact of s…
Intersecting near-optimal spaces: European power systems with more resilience to weather variability
Aleksander Grochowicz, Koen van Greevenbroek, Fred Espen Benth +1
We suggest a new methodology for designing robust energy systems. For this, we investigate so-called near-optimal solutions to energy system optimisation models; solutions whose ob…
Overcoming the disconnect between energy system and climate modeling
Michael T. Craig, Jan Wohland, Laurens P. Stoop +20
Energy system models underpin decisions by energy system planners and operators. Energy system modelling faces a transformation: accounting for changing meteorological conditions i…
