However, in case of curtailment of the Plant due to market control, active power increase up to the available power is
possible. As the inverter is not able to distinguish P constant set values between mandatory congestion management of
the grid operator and market control this needs to be implemented in the site specific plant control infrastructure.

Power reference with overfrequency:
Power reference for power adjustment as in equation 6 and equation 7
for overfrequency incidents.
Power reference with underfrequency:
Power reference for power adjustment as in equation 6 and equation 7
for overfrequency incidents.
Activation threshold
with overfrequency
50.2 – 70 (Hz)
Activation threshold
with underfrequency
40 – 45 (Hz)
Activation threshold (f1) overfrequency:
Determines the frequency threshold for activating the function in case
of overfrequency incidents. The active power adjustment is activated if
the frequency rises above the configured value and mode 1 or 2 is acti-
vated.
In mode 2, the function is deactivated if the frequency falls below the
configured value.
Activation threshold (f1) underfrequency:
Determines the frequency threshold for activating the function in case
of underfrequency incidents. The active power adjustment is activated if
the frequency falls below the configured value and mode 1 or 2 is acti-
vated.
In mode 2, the function is deactivated if the frequency rises above the
configured value.
