The operating points are examples for different areas within the operating
characteristic.
Operating point -1-:
Voltage control cv with a ULoad limit at UREF or current control cc
with an ILoad limit at ILimitQ4.
Operating point -2-:
Voltage control cv with a ULoad limit at UREF or power control cp,
from PLoad to PLimitQ4.
Operating point -3-:
Voltage control cv with a ULoad limit at UREF=UNOM.
Operating point -4-:
Power control cp, from PLoad to PLimitQ4= Pmax.
Operating point -5-:
Current control cc with an ILoad limit at ILimitQ4=Imax
