Work package 5 focuses on the categorisation of each energy system model. Therefore, model runs will be conducted with different scenarios resulting from WP4. Due to the nature of the different modelling approaches, results will vary between the models. In order to enhance the understanding of the different model effects, an in-depth analysis is necessary. The partners will develop a systematic analysis method with which the models will be compared. The work package will first generate model solutions which span a space of relevant political scenarios. These allow the analysis of the sensitivities regarding technologic, economic and social determinants. Results will give insights for best-practice-models and best-practice-modelling-standards. This outcome could be crucial to improve the transparency and comparability of energy system models in the context of political relevant energy system issues.
