Communication
abnormality output (%)
Communication is abnormal, and specified dispatch output
value is delivered.
Control method
Open loop control: Active instruction controlled by AI is sent
to the power output port of the inverter, thereby achieving
active power control.
Closed-loop control:
•
In case no Smart Energy Meter is selected, active
instruction controlled by AI is used as target value, and
active power compensation ratio is calculated and sent
to the power output port of the inverter. Generally, this
strategy is used for fast and accurate active power
regulation.
•
In case a Smart Energy Meter is selected, active
instruction controlled by AI is used as target value,
active power of the meter needs to be collected and
used
as
input
parameter,
and
active
power
compensation ratio is calculated and sent to the power
output port of the inverter. Generally, this strategy is
used for anti-backflow or avoiding zero power feed-in.
