Reactive power characteristics are designed to describe reactive power control behaviour of the models. In Germany, system operators can require system participants to follow certain characteristics specified in the operators technical requirements and individually selected per connected asset.
Currently three different characteristics are implemented:
Active and reactive power are coupled by a time-independent power factor.
It can be parsed from {code}cosPhiFixed:{(0.0, 0.95)} (exemplary).
The power factor is determined based on the current active power feed in or consumption.
The characteristic in the figure below would be described by the three coordinates (0.0, 1.0), (0.9,1.0) and (1.0, 0.95).
Alternatively it can be parsed from {code}cosPhiP:{(0.0, 1.0),(0.9,1.0),(1.0, 0.95)}.

The reactive power is directly derived in accordance to the nodal voltage magnitude.
The characteristic in the figure below would be described by the three coordinates (0.92, -1), (0.97, 0.0), (1.03, 0.0)
and (1.08, 1.0).
Alternatively it can be parsed from {code}qV:{(0.92, -1),(0.97, 0.0),(1.03, 0.0),(1.08, 1.0)}.
