mp.dme_legacy_dcline

class mp.dme_legacy_dcline

Bases: mp.dm_element

mp.dme_legacy_dcline - Data model element for legacy DC line.

Implements the data element model for legacy DC line elements, with linear line losses.

\(p_\mathrm{loss} = \param{l}_0 + \param{l}_1 p_\mathrm{fr}\)

Adds the following columns in the main data table, found in the tab property:

Name	Type	Description
bus_fr	integer	bus ID (uid) of “from” bus
bus_to	integer	bus ID (uid) of “to” bus
loss0	double	\(\param{l}_0\), constant term of loss function (MW)
loss1	double	\(\param{l}_1\), linear coefficient of loss function (MW/MW)
vm_setpoint_fr	double	per unit “from” bus voltage magnitude setpoint
vm_setpoint_to	double	per unit “to” bus voltage magnitude setpoint
p_fr_lb	double	lower bound on MW flow at “from” port
p_fr_ub	double	upper bound on MW flow at “from” port
q_fr_lb	double	lower bound on MVAr injection into “from” bus
q_fr_ub	double	upper bound on MVAr injection into “from” bus
q_to_lb	double	lower bound on MVAr injection into “to” bus
q_to_ub	double	upper bound on MVAr injection into “to” bus
p_fr	double	MW flow at “from” end (“from” –> “to”)
q_fr	double	MVAr injection into “from” bus
p_to	double	MW flow at “to” end (“from” –> “to”)
q_to	double	MVAr injection into “to” bus
