Determines the dynamic behaviour in the event of a change in the ac-
tive power set value. With a voltage change, the active power is
changed according to a PT-1 characteristic curve with a settling time of
5 Tau.
Note: The settling time is overlaid with the increasing and decreasing
gradient.

10.2.4 P(f)
P(f) Active power response to overfrequence
Feed-in inverters must assist with frequency stability in the grid. If the grid frequency leaves the normal toler-
ance range (e.g. ±200 mHz), the grid is in a critical state. In the event of overfrequency, there is a generation
surplus, in the event of underfrequency, there is a generation deficit.
PV-Systems must adapt their active feed-in power in relation to the frequency deviation. In case of overfre-
quency the adaption of power is defined by a maximum feed-in limit. The actual power of the inverter may
vary freely below this limit based on possible fluctuation of the available power or set point, but will never in-
crease above the absolute power limit.
