The energyRt model comprises around one hundred
predefined equations describing energy technologies, the energy system,
and its operation. Additional equations can be added with
newConstraint() or directly in the model code. The model is
formulated in four alternative math-programming languages: GAMS,
Python/Pyomo,
GLPK/Mathprog,
and Julia/JuMP.
The mathematical formulation is documented in the model
equations PDF; for the concepts behind the package, start with the
introduction
vignette.
