Adding component values to the pypsa Network manually

[swagat panda]

Hello Everyone,

I have a small question. I want to add all network components to an empty pypsa network manually using normal pandas dataframe manipulations, instead of Network.add or .madd methods.

 Will that cause any unwanted or undetectable issues later on during lopf?  Are there some attributes that will not be modified by this? (On visual inspection of the NetCDF file I didn't notice any difference)

----

Thanks and Regards

Hi Swagat,

there are also functions to import components from dataframes

https://pypsa.readthedocs.io/en/latest/import_export.html#adding-components-using-pandas-dataframes

Maybe that's useful.

Best wishes

Hi Fabian,

Thanks for the answer. It's a lifesaver 😊. But still, for the sake of clarity, it is also okay to use custom methods using

pandas dataframe to insert components and values, right?

Yes, I think so. You may just need to be extra careful with providing
suitable values for every attribute as the defaults won't apply
automatically.

You may want to use n.consistency_check().
