The transparency and availability of energy system models and their input data are of particular importance due to the increasing systems complexity and policy relevance. In recent years, a large number of model-based scenario analyses have been carried out. These analyses are based on various model approaches and lead to a range of results, which due to different data structures and mathematical approaches seem hardly comparable.

In this investigation, we attempt to develop an understanding of different electricity system models and their mathematical approaches through systematic model comparison to facilitate comparison of model results. Detailed and harmonized scenario input parameters are the basis of this model experiment including the electricity system models IDILES-JMM1, PowerACE2 and ELTRAMOD3.

The focus is on a selection of output parameters, such as investment and dispatch decisions in flexible power plants, storage dispatch, carbon emissions and generation adequacy in hours with critical supply situations with a focus on Germany and a considered time horizon until 2030.

The results indicate that all models see a need for investments in flexible power plants of at least 2.6 GW until 2030. ... mehr
