LTM and LTM-API¶
This is the combined documentation of LTM (EMPS/EOPS) and LTM-API.
End user experience comparing LTM (EMPS/EOPS) with LTM-API.¶
Motivating example¶
In a couple of lines of code it is possible to add or remove areas, add dclines, assign loads, capacities and much more.
# Add busbars (areas)
numedal = session.model.add("busbar", "numedal")
tev = session.model.add("busbar", "tev")
# Add DC-line
dc = session.model.add("dcline", "dc_numedal_tev")
# Connect DC between areas
session.connect(numedal, dc)
session.connect(dc, tev)
This, and much more is possible with LTM-API.
The notebook Live LTM contains a minimal example.
