AnyMOD is a Julia framework to create large scale energy system models with multiple periods of capacity expansion formulated as linear optimization problems.
It was developed to address the challenges in modelling high-levels of intermittent generation and sectoral integration, as addressed by the WP1 activities of the OSMOSE project, defining 2050 scenarios of quantified system flexibilities.
The latest documented and unit-tested version of AnyMOD.jl is available on GitHub. Its underlying graph-based modelling approach is described in a paper of Leonard Göke from Technische Universität Berlin available here. You can also find an introductory presentation there.
