Hi there,
I am wondering if anyone could enlighten me on how the FIXBOH option in VEDA works? I am currently creating mitigation scenarios, where I fix action up to 2020 based on a reference scenario which captures only current climate and energy policies.
When I look at the results in VEDA_BE however, the results in 2020 for the mitigation run are very slightly different to the results for the Reference Scenario - so they haven't been entirely fixed - for example emissions or system costs show slight deviations between the scenarios.
I am:
- Running with price-elastic demand, and using this same Reference Scenario to generate the base prices - could this be responsible for the (small) deviation? Is it recommended to do this differently (i.e. use different scenarios for fixing initial periods and generating base prices)?
- I am also sometimes evolving technology costs between the scenarios (e.g. solar costs in 2020 may differ between the scenarios). I can see that this could be the problem.
When using FIXBOH, does the model simply overwrite initial periods with data from the Reference Scenario .gdx? If so, I am confused as to where the difference arises.
If anyone could enlighten me further, that would be very appreciated.
Cheers,
Neil
