Create Function
- pandapower.create.create_bus_dc(net, vn_kv, name=None, index=None, geodata=None, type='b', zone=None, in_service=True, max_vm_pu=nan, min_vm_pu=nan, coords=None, **kwargs)
Adds one dc bus in table net[“bus_dc”].
Buses are the nodes of the network that all other elements connect to.
- Parameters:
net (pandapowerNet) – The pandapower network in which the element is created
vn_kv (float) – The grid voltage level.
name (str | None) – the name for this dc bus
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.
geodata (tuple[float, float] | None) – coordinates used for plotting
type (Literal['n', 'b', 'm']) – Type of the bus. “n” - node, “b” - busbar, “m” - muff
zone (str | None) – grid region
in_service (bool) – True for in_service or False for out of service
max_vm_pu (float) – necessary for OPF
min_vm_pu (float) – necessary for OPF
coords (list[tuple[float, float]] | None) – busbar coordinates to plot the dc bus with multiple points. coords is typically a list of tuples (start and endpoint of the busbar) - Example: [(x1, y1), (x2, y2)]
- Returns:
The unique ID of the created element
- Return type:
int | integer
Example
>>> create_bus_dc(net, 20., name="bus1")
- pandapower.create.create_buses_dc(net, nr_buses_dc, vn_kv, index=None, name=None, type='b', geodata=None, zone=None, in_service=True, max_vm_pu=nan, min_vm_pu=nan, coords=None, **kwargs)
Adds several dc buses in table net[“bus_dc”] at once.
Buses are the nodal points of the network that all other elements connect to.
- Parameters:
net (pandapowerNet) – The pandapower network in which the element is created
nr_buses_dc (int) – The number of dc buses that is created
vn_kv (float | Iterable[float]) – The grid voltage level.
index (int | integer | Iterable[int | integer] | None) – Force specified IDs if available. If None, the indices higher than the highest already existing index are selected.
name (Iterable[str] | None) – the name for this dc bus
type (Literal['n', 'b', 'm'] | ~typing.Iterable[~typing.Literal['n', 'b', 'm']]) – Type of the bus. “n” - auxiliary node, “b” - busbar, “m” - muff
geodata (Iterable[tuple[float, float]] | None) – (x,y)-tuple or list of tuples with length == nr_buses_dc, coordinates used for plotting
zone (str | None) – grid region
in_service (bool | Iterable[bool]) – True for in_service or False for out of service
max_vm_pu (float | Iterable[float]) – necessary for OPF
min_vm_pu (float | Iterable[float]) – necessary for OPF
coords (list[list[tuple[float, float]]] | None) – busbar coordinates to plot the dc bus with multiple points. coords is typically a list of tuples (start and endpoint of the busbar) - Example for 3 dc buses: [[(x11, y11), (x12, y12)], [(x21, y21), (x22, y22)], [(x31, y31), (x32, y32)]]
- Returns:
The unique indices ID of the created elements
- Return type:
ndarray[tuple[Any, …], dtype[int | integer]]

>>> create_buses_dc(net, 2, [20., 20.], name=["bus1","bus2"])
