Column headers in scenario option data

[HauHe]

I encounter an error when providing options for the AnnualEmissionLimit.
Problem is that in the file in which the options are provided the column headers don't correspond to the headers of the parameter. For AnnualEmissionLimitthis should be: ['REGION', 'EMISSION', 'YEAR', 'VALUE'], but in the scenario option file it is ['REGION', 'TECHNOLOGY', 'YEAR', 'VALUE'].

The problem is that the file with the scenario options might contain data for multiple parameter that are to be modified for the scenarios. Hence, the header should not be taken from the scenario file, but from the otoole configuration file. In an older version it must have been like that already, since I ran the scenarios that I was about testing already. So not sure when we missed that.

The loop that would need modification I think starts in line 190 and following in main.py

@trevorb1 , would you be able to have a look at it?

@HauHe can you please provide an example of how you were specifying the annual emission limit in the scenario folder? Thank you!

Hi @trevorb1, sure, please see below:
PARAMETER,REGION,TECHNOLOGY,OPTION,YEAR,VALUE AnnualEmissionLimit,UTOPIA,NOX,0,,-50 AnnualEmissionLimit,UTOPIA,NOX,1,,-10000

Hi @trevorb1 ,
sorry for the long silence, was a bit difficult to find the time to work on this.
In the original version of OSeMOSYS_step, I had written some code that allowed to instead of providing a series of values for each year in the options, to provide a single value that could be either absolute or a percentage, indicated via the %-symbol. This only worked if the parameter was already defined in the step before, if not an error was produced. I think this feature is very useful since it allows to have changes in parameters over the modelling time horizon without having jumps, since you are indicating the change of the parameter an not the absolute value.
I think it would be great if we could reintroduce this feature.
