      abstract = {Mitigation-Process Integrated Assessment Models (MP-IAMs)  are used to analyze long-term transformation pathways of  the energy system required to achieve stringent climate  change mitigation targets. Due to their substantial  temporal and spatial aggregation, IAMs cannot explicitly  represent all detailed challenges of integrating the  variable renewable energies (VRE) wind and solar in power  systems, but rather rely on parameterized modeling  approaches. In the ADVANCE project, six international  modeling teams have developed new approaches to improve the  representation of power sector dynamics and VRE integration  in IAMs. In this study, we qualitatively and quantitatively  evaluate the last years’ modeling progress and study the  impact of VRE integration modeling on VRE deployment in IAM  scenarios. For a comprehensive and transparent qualitative  evaluation, we first develop a framework of 18 features of  power sector dynamics and VRE integration. We then apply  this framework to the newly-developed modeling approaches  to derive a detailed map of strengths and limitations of  the different approaches. For the quantitative evaluation,  we compare the IAMs to the detailed hourly-resolution power  sector model REMIX. We find that the new modeling  approaches manage to represent a large number of features  of the power sector, and the numerical results are in  reasonable agreement with those derived from the detailed  power sector model. Updating the power sector  representation and the cost and resources of wind and solar  substantially increased wind and solar shares across  models: Under a carbon price of 30$/tCO2 in 2020  (increasing by 5% per year), the model-average  cost-minimizing VRE share over the period 2050-2100 is 62%  of electricity generation, 24%-points higher than with the  old model version.},
