This paper presents the results of a multi-model comparison to determine outcome deviations resulting from differences in power system models. We apply eight temporally and spatially resolved models 16 stylized test cases. These cases differ their renewable energy supply share, technology scope, optimization scope. focus on technologies for balancing variability generation, such as controllable plants, storage, transmission, flexibility related sector coupling. use harmonized input data all...
The transition towards decarbonized energy systems requires the expansion of renewable and flexibility technologies in power sectors. Many powerful tools exist to find optimal capacity expansion. In a stylized comparison six models, we evaluate results basic sector technologies. under investigation include base- peak load plants, electricity storage, transmission. We define four highly simplified harmonized test cases that focus on only one or two specific isolate their effects model...
Model-based scenario analyses of future energy systems often come to deviating results and conclusions when different models are used. This may be caused by heterogeneous input data inherent differences in model formulations. The representation technologies for the conversion, storage, use, transport is usually stylized comprehensive system order limit size mathematical problem, substantially differ between models. paper presents a systematic comparison nine power sector with coupling. We...
A reliable and cost-effective electricity system transition requires both the identification of optimal target states definition political regulatory frameworks that enable these to be achieved. Fundamental optimization models are frequently used for determination cost-optimal configurations. They represent a normative approach typically assume markets with perfect competition. However, it is well known real systems do not behave in such an way, as decision-makers have information at their...
A novel experimental approach of inter- and intramodel comparisons is conducted with five power market models to give recommendations for modelers working on decarbonization pathways Europe until 2050. The experiments investigate the impact model type (optimization vs. simulation), planning horizon (intertemporal myopic), temporal resolution (8760 384 hours), spatial (28 countries 12 mega-regions). fundamentally determines evolution capacity expansion. Planning (assumed foresight firms)...
The transition towards decarbonized energy systems requires the expansion of renewable and flexibility technologies in power sectors. In a model comparison, we examine optimal such with six capacity system models. under investigation include base- peak-load plants, electricity storage, transmission. We define four highly simplified harmonized use cases that focus on only one or two specific to isolate their effects results. find deviating assumptions limited availability factors cause...
