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.

Input Parameters

net.sgen

Parameter	Datatype	Value Range	Explanation
name	string		name of the static generator
type	string		type of source
bus*	integer		index of connected bus
p_mw*	float	\(\leq\) 0	active power of the static generator [MW]
scaling*	float	\(\geq\) 0	scaling factor for the active and reactive power
controllable**	bool	True / False	states if sgen is controllable or not, sgen will not be used as a flexibility if it is not controllable
in_service*	boolean	True / False	specifies if the generator is in service.

*necessary for executing a power flow calculation

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:

\begin{align*} P_{sgen} &= p\_mw \cdot scaling \\ \end{align*}

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 Parameters

net.res_source_dc

Parameter	Datatype	Explanation
p_mw	float	resulting active power demand after scaling [MW]

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