Does the powergui block perform AC-DC loadflow when I use synchronous machine connected to my system

This is my system

Synchronous machine----Transformer-----3level VSC( SPWM firing)---dc link----3level VSC(Inv)---transformer-----3ph parallel load-----3ph source.

When I open the powergui block and click "solve load flow", its doesn't consider the load at the inverter end . It just considers the parasitic load connected to the sync mach( parasitic load should be connected as give in demo of sync mach) and calculates the power in pu.
In my case the value is 0.2e6/36e6 =0.005 pu.
This is the Pmec which is to be specified as input to the governor.

Can someone help me with this??
