Error when creating gas demand time series for 2011

[wheitkoetter]

Dear DemandRegioTeam,

thanks for the great work and developing the disaggregator tool.
As part of the eGon project we would also like to use the disaggregator results. At DLR we are responsible for the gas sector.

I executed the 04_Demo_temporal_disaggregations.ipynb with the standard settings for the year 2015 without having problems.

As we want to use 2011 as weather year in the eGon project, I set base_year: 2011 in config.yaml.

While data.elc_consumption_HH_spatiotemporal() still worked fine, data.standard_load_profile_gas(typ='MFH') resulted in the following error meassage:
File "04_Demo_temporal_disaggregations_v2.py", line 170, in
df_temp_MFH = data.standard_load_profile_gas(typ='MFH')
File "C:\Users\heit_wi\disaggregator-master\disaggregator-master\disaggregator\data.py", line 1468, in standard_load_profile_gas
df_slp = reshape_spatiotemporal(key='slp_H0_1H_gas', **kwargs)
File "C:\Users\heit_wi\disaggregator-master\disaggregator-master\disaggregator\data.py", line 1831, in reshape_spatiotemporal
internal_id=internal_id, force_update=force_update)
File "C:\Users\heit_wi\disaggregator-master\disaggregator-master\disaggregator\data.py", line 1965, in database_get
return database_raw(query, force_update=force_update)
File "C:\Users\heit_wi\disaggregator-master\disaggregator-master\disaggregator\config.py", line 108, in database_raw
raise ValueError('The returned pd.DataFrame is empty!')
ValueError: The returned pd.DataFrame is empty!

Correspondingly,
http://opendata.ffe.de:4000/demandregio_temporal?id_temporal=eq.28&&year_weather=eq.2015&&internal_id=eq.{1}
yields results, when opening it in a browser, while
http://opendata.ffe.de:4000/demandregio_temporal?id_temporal=eq.28&&year_weather=eq.2011&&internal_id=eq.{1}
does not yield result data.

Is it thus not possible to generate gas demand time series with the disaggregator tool for 2011 using the current release without changing the code / adding additional wheather data etc.? Or am I doing something wrong?

Thanks in advance!

Dear Wilko,
thank you for pointing this out. You did fine, however the available data did not allow you to calculate any other year at that point.
I closed the data-gap now by introducing a new function which works similar to the one that is used for the temporal gas demand in CTS. The new function is called disagg_temporal_gas_households(). You can find an update on how to use this function in 04_Demo_temporal_disaggregations.ipynb.

Dear Paul,

thanks a lot for fixing! I will try to test it as soon as possible.

Best regards
