This report also describes the protocol for model linking in SURE when quantifying the SURE scenarios. It provides an extensive overview of the inputs and outputs exchanged between the models and their sequence in the quantification, indicating which model starts and which model follows. Several notions of the linking approach are explained, supported by mathematical formulations where necessary. The discussion in the report concludes with an overview of the main challenges and risks in the model linking, as well as the value added in the analysis obtained by linking the models in the scenario quantification compared to the case where the models run “unlinked.”
We hope the insights presented in this report facilitate the interpretation of the SURE pathway scenarios and provide transparency on their implementation in the models. In addition, we hope that the report helps set the context within which stakeholders should evaluate the obtained results. Finally, the insights on the linking of diverse models (in terms of logic and scope) could be useful for the broader scientific community, as it tackles many challenges associated with consistency and convergence between the general and partial equilibrium models, as well as between energy systems and sectoral models.
This report complements the report “1st scenario protocol capturing the definition of pathway and shock scenarios” and the “Repository of common assumptions used in the definitions of the scenarios and disruptive events,” an Excel file with extensive tables on key numerical inputs to the models.
