Source DC

Note

Sources should always have a positive p_mw value, since all power values are given in the generator convention. If you want to model constant power consumption, it is recommended to use a load element instead of a source with negative active power value.

Create Function

pandapower.create.create_source_dc(net, bus_dc, vm_pu=get_default_value('source_dc', 'vm_pu'), index=None, name=None, in_service=get_default_value('source_dc', 'in_service'), type=None, **kwargs)

Creates a dc voltage source in a dc grid with an adjustable set point

Parameters:

• net (pandapowerNet) – The pandapower network in which the element is created

• bus_dc (int | integer) – index of the bus the shunt is connected to

• vm_pu (float) – set-point for the bus voltage magnitude at the connection bus

• name (str | None) – element name

• index (int | integer | None) – Force a specified ID if it is available. If None, the index one higher than the highest already existing index is selected.

• in_service (bool) – True for in_service or False for out of service

• type (str | None) – A string describing the type.

Returns:

The ID of the created svc

Table Structure

Parameter	Datatype	Value Range	Explanation	nullable	required
name			name of the static generator	✓
type			type of source	✓

Electric Model

DC sources are modelled as P-buses in the power flow calculation:

The P-Values are calculated from the parameter table values as:

\[P_{sgen} = p\_mw \cdot scaling\]

Note

Other values are provided as additional information for usage in controller or other applications based on pandapower. It is not considered in the power flow!

Result Table

net.res_source_dc

Parameter	Datatype	Explanation	nullable	required
p_dc_mw	float	resulting active power demand after scaling [MW]	✓	✓

The power values in the net.res_source_dc table are equivalent to \(P_{sgen}\).
