Create Function

pandapower.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)

• **vn_kv** (float)

• **name** (string, default None)

• **index** (int, default None)

• **geodata** ((x,y)-tuple, default None)

• **type** (string, default "b")

• busbar ("b" -)

• muff ("m" -)

• **zone** (string, None)

• **in_service** (boolean)

• **max_vm_pu** (float, NAN)

• **min_vm_pu** (float, NAN)

• **coords** (list (len=2) of tuples (len=2), default None)

• of (the dc bus with multiple points. coords is typically a list of tuples (start and endpoint)

• Example (the busbar) -) – [(x1, y1), (x2, y2)]

• net (pandapowerNet)

• vn_kv (float)

• name (str | None)

• index (int | integer | None)

• geodata (tuple[float, float] | None)

• type (Literal['n', 'b', 'm'])

• zone (str | None)

• in_service (bool)

• max_vm_pu (float)

• min_vm_pu (float)

• coords (list[tuple[float, float]] | None)

Returns:

index (int) - The unique ID of the created element

Return type:

int | integer

Example

create_bus_dc(net, 20., name=”bus1”)

Input Parameters

net.bus_dc

Parameter	Datatype	Value Range	Explanation
name	string		name of the dc bus
vn_kv*	float	\(>\) 0	rated voltage of the dc bus [kV]
type	string	naming conventions: “n” - node “b” - busbar “m” - muff	type variable to classify buses
zone	string		can be used to group dc buses, for example network groups / regions
in_service*	boolean	True / False	specifies if the dc bus is in service

*necessary for executing a power flow calculation

Note

Bus voltage limits can not be set for slack buses and will be ignored by the optimal power flow.

net.bus_dc_geodata

Parameter	Datatype	Explanation
x	float	x coordinate of dc bus location
y	float	y coordinate of dc bus location

Electric Model

Result Parameters

net.res_bus_dc

Parameter	Datatype	Explanation
vm_pu	float	voltage magnitude [p.u]
p_mw	float	resulting active power demand [MW]

The power flow bus results are defined as:

\begin{align*} vm\_pu &= \lvert \underline{V}_{bus} \rvert \\ p\_mw &= Re(\sum_{n=1}^N \underline{S}_{bus, n}) \\ \end{align*}
