@smartie2076 and I discussed today implications that might occur having two output busses at a transformer component.

It is important to know which parameters are connected to which bus (input or output). In case a parameter is connected to the output bus(es) they need to be declared as a list, for example:

• outflow_direction: ["Output_direction_1", "Output_direction_2"]
• capex_var: [Output_dir_1_capex_var, Output_dir_2_capex_var]

Question to answer:
Are the capex_var connected to input or output busses?
Are there any other parameters we aren't sure of, yet?

Of course this information needs to go into the documentation.
