A capacity expansion model of the electricity system for arbitrary world regions, written in Julia.
First, install the CPLEX and/or Gurobi solvers on your system and make sure that they work at the command prompt and are properly licensed. Both are free for academic use (students or faculty).
Next, type ] to enter Julia's package mode, then:
(v1.3.1) pkg> add [email protected]
(v1.3.1) pkg> add AxisArrays
(v1.3.1) pkg> add https://github.com/niclasmattsson/Supergrid
Grab some coffee, because installing and compiling dependencies can take quite some time to run.
julia> using Supergrid, AxisArrays
julia> r, annualelec, capac, tcapac, chart = runmodel(regionset=:Europe8, carboncap=0.1, hours=3);
Note that if you forget the last semicolon a LOT of results will get dumped to the console. Expect a long delay for precompiling the first time you run using Supergrid.

)
julia> chart(:BARS) # regional annual electricity generation and a separate bar chart with global totals
julia> chart(:GER) # [or any other region name] hourly electricity generation in that region and usage of renewable resource classes
julia> chart(:TOT) # same as previous except for global totals (aggregate of all regions)
By default all results from model runs are saved to a database so you can reload them and produce new charts in another Julia session without having to re-run the model (to avoid saving a run, add the option resultsfile="" to the runmodel() command).
julia> listresults()

└─� hours=3, carboncap=50.0
julia> r = loadresults("hours=3, carboncap=50.0"); # copy/paste the run name *exactly* as it appears in the listing above.
julia> annualelec, capac, tcapac, chart = analyzeresults(r);
