Hi All,
I am designing LCL filter for a grid-connected converter. I am wondering how can I calculate the damper resistance power?


Thank you for your comments,
 

It will be exactly 0.2% of the total kVA of the GCI .....
 

I searched and I found this. The calculation sounds correct in this paper, so we can calculate by using this paper:
IEEE TRANSACTIONS ON POWER ELECTRONICS, VOL. 28, NO. 6, JUNE 2013
Analysis of the Passive Damping Losses in LCL-Filter-Based Grid Converters
