Is there know about Feed-forward control of the 3phase solar Inverter to tie Grid?
(solar inverter is using the transformer(D-Y))
There are two Parameter.
IPARK.Ds = PID_Id.out; (using for the Reactive Power)
IPARK.Qs = PID_Iq.out; (using for the Active Power)
How can i change?
ex) unit = 1pu.
IPARK.Ds = PID_Id.Out - wL * PID_Iq.Ref + VPARK.Ds;
IPARK.Qs = PID_Iq.Out + wL * PID_Id.Ref + VPARK.Qs;
Here w = 2*pi*f (rad/s), L = Inverter Reactance
Thanks.
