Adjusting the active power P(f) in the event of overfrequency
Feed-in inverters must assist with frequency stability in the grid. If the grid frequency leaves the normal
tolerance range (e.g. ±200 mHz), then the grid will be 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 feed-in power relative to the frequency deviation. In the event of overfre-
quency, the power adjustment is determined by a maximum feed-in limit. The actual power of the in-
verter may vary freely below this limit due to a possible fluctuation in the available power or the target
value, but at no time increases above the absolute power limit.

Action in this menu/meaning
If the available power is above the actual output at the time of deactiva-
tion, the power increase back to the maximum power is limited. The li-
mitation is implemented by an absolute power limitation that increases
with a continuous gradient up to the maximum power. The actual po-
wer of the inverter may vary freely below this limit due to a possible
fluctuation in the available power or the target value, but at no time in-
creases above the absolute power limit.
Only evaluated with activated hysteresis mode: Monitoring time during
which the voltage must remain below the lowest configured node befo-
re the function is deactivated.
Determines the dynamic behaviour in the event of a change in the acti-
ve 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.
Up to five nodes for voltage [V] and power [% Pref] are configurable.
The power value of the first and last value pair is also used as the maxi-
mum or minimum active power value that is valid across the limits of
