Parameters Description
Control Method
• Open-Loop Control: Active dispatching command is sent to the
power output port of the inverter, thereby achieving active power
control.
•
Closed-Loop Control:
- When not using a Smart Energy Meter, at the start time,
the active power command is set as the target value.
Multiple adjustment algorithms are applied to calculate the
proportional value of active power compensation, which
is then sent to the power output port of the inverter. This
method is generally used for fast and accurate active power
regulation.
- When using a Smart Energy Meter, at the start time, the
active power command is set as the target value, and the
active power is collected by the meter as an input parameter.
A closed-loop control algorithm is then used to calculate the
proportional value of active power compensation, which is
then sent to the power output port of the inverter. This method
is generally used for anti-backflow or zero power feed-in.
