This constraint is problematic since it will disallow the installment of technologies that do not have initial capacity at 0. The solution other models use is to add a "seed" value that sets an allowed max initial install.

I catch this below (where: investsteps=get_val_at_index(investsteps=0) AND flow_cap_initial > 0). If there is no initial flow cap, there is no constraint in the first timestep.

accidental keystroke?

Let's start by setting the growth rate to be the same constant (0.5?) for everything.
These values are often used by modellers to "tune" results, and there is no agreed measurement for them. They are neither physical or economical "properties" of anything, and they may mask formulation issues (e.g., EoH, extreme discounting).
Agreed the naming is murky. I'd argue that the "stationary" model is also "constrained" though. It sets a progressively lower available initial capacity per investment step. Maybe I expunge the |

That would work. We should ensure that the base case is not dynamic in that sense. |
Since so much of the underlying data remains the same for a "stationary" vs "dynamic" italian model, it seems to make sense to rely on the same model, just with scenarios to add in additional functionality.
This PR adds in a "dynamic" scenario, which involves setting a maximum rate of capacity expansion for certain technologies. This stops massive jumps in technology capacity between investment steps, although setting the rates to something sensible will require some research.
