Using multiple in- or output busses

Sometimes, you may also want to have multiple input or output busses connected to a component. This is for example the case if you want to model an electrolyzer with a transformer, and want to track water consumption at the same time as you want to track electricity consumption.

You can define this, again, in the csv´s. First you should provide the input, or output, busses as a list for the energyConversion.csv parameter of inflow_direction or outflow_direction resp.:

“[h2o_bus, electricity_bus]”

Then you need to provide the efficiencies and dispatch prices respective to each bus, for example:

“[0.99, 0.98]”

You can also provide a timeseries for one or both values. To do so, you can simply use the notation introduced in Adding a timeseries for a parameter:

“[0.99, {‘value’: {‘file_name’: ‘your_file_name.csv’, ‘header’: ‘your_header’}, ‘unit’: ‘your_unit’}]”

You can see an example here, with an electrolyzer :

Example for defining a component with multiple inputs/outputs

	unit	electrolyser
age_installed	year	3
development_costs	currency	0
specific_costs	currency/kW	1500
efficiency	factor	“[0.01923,0.28845]”
inflow_direction	str	“[MicroGrid,Water]”
installedCap	kW	0
label	str	Electrolyser
lifetime	year	20
specific_costs_om	currency/kW/year	75
dispatch_price	currency/kWh	“[0,0.0038]”
optimizeCap	bool	True
outflow_direction	str	Local H2 grid
energyVector	str	Electricity
type_oemof	str	transformer
unit	str	kW

The features were integrated with Pull Request #63 and Pull Request #949.

For more information, you might also reference following issues:

• Parameters can now be a list of values, eg. efficiencies for two busses or multiple input/output vectors(Issue #52)

• Parameters can now be defined as a list as well as as a timeseries (Issue #52, Issue #82)
