Including system integration of variable renewable energies in a constant elasticity of substitution framework: The case of the WITCH model

摘要

The penetration of variable renewable energies (VREs) in the electricity mix poses serious challenges in terms of management of the electrical grids, as the associated variability is in contrast with the requirement that the load be instantaneously equalized by the generation. One of the goals of Integrated Assessment Models (IAMs) is to simulate the evolution of electricity demand and generation mix over time, therefore a proper modeling of VRE system integration is crucial.
