laurinks · 2024-10-10T15:08:31Z

Purpose of this PR

Clean-up of 45_carbonprice module:

Remove realizations diffCurvPhaseIn2Lin (superseded by diffLin2Lin), exponential (superseded by diffExp2Lin) and linear (superseded by diffLin2Lin),
Consistent update of scenario config files (affects project files),
Improved documentation of diffLin2Lin and diffExp2Lin in main.gms.

Not sure if this module is still in use. Nonetheless cleaned it up. Previously, it just used a copy-paste version of the 45_carbonprice/exponential with exponentially increasing carbonprices from 2010 onward (with the 2020 value set to 0,30,150). For simplicity, I reduced it to one line of code. Now, it is still exponentially increasing from 2010 onward but the startyear (default = 2005) value is set to 0,30,150.

I have to admit I did not check everything in detail, but overall it looks very convincing. Thanks for investing in checking documentation and tutorials, that is very appreciated! Also thanks for providing the human-readable summary of the config file changes!

thanks for all that cleaning!
the scenario:config.csv file is already using teh new formulation, right?

laurinks · 2024-10-11T11:53:48Z

Thanks for the reviews! @LaviniaBaumstark : Yes, diffLin2Lin was introduced as the REMIND default in PR#1747. That's why the clean-up changes now only affect some project configs.
