Parameters
Figure 54: Power reduction gradient level
PM: Instantaneously Available Power
∆P: Power Reduction (Power Reduction Gradient Level)
This function controls active power which is proportional to Grid frequency increase. As you can see in the pic-
ture, active power need to be restricted if grid frequency is over 50.2Hz. PM (Instantaneously available power)
decreases with 40%/Hz slope and it can be restorable if grid frequency is less than 50.05Hz.
8.3.4 Power Gradient Enable On
Figure 55: PV gradient graph
This function is for PV inverter re-generation. Inverter need to generate active power slowly with specific slope
when its operation stops due to various reasons. In this case, active power supply cannot be over 10% of rated
active power per minute.
