Control method
Open loop control: Reactive instruction controlled by AI is sent
to power output port of the inverter, thereby achieving active
power control.
Closed-loop control: Reactive instruction controlled by AI is
used as target value and reactive power and power factor of
the meter need to be collected and used as input parameters,
and reactive power compensation ratio is calculated and sent
to power output port of the inverter. Generally, this strategy is
used for improving the power factor of the property boundary
point.
