Abstract

Integrated Assessment Models (IAMs) are vital for identifying potential pathways for the longterm development of the global energy system in line with set climate targets to keep global temperature rise well below 2°C and to further pursue efforts to limit temperature rise to 1.5°C. IAMs cover a broad spectrum of energy demand and supply sectors while simultaneously having the ability to account for interlinked impacts on ecological and economic systems. Due to their broad scope, global IAMs are limited in detail regarding spatial and temporal modelling resolution. Significant improvements have been made in recent years regarding power system representation in global IAMs. However, ongoing concerns exist within the scientific community regarding the suitability of global IAMs to properly simulate the challenges that arise with integration of vast quantities of variable renewable energy sources in the global power system.
