How to get the power generation D-curves(reactive capability curves)?

I already build the SMIB to the power generation. My generator is connected to the step up transformer and then connect to the SMIB. I already set the Sbase, Pmax, Pmin, Qmax, Qmin. By changing Pgen, I can get different Q gen value. However, the result is not good enough, because

when I already set the Pgen to Pmax, there is still some Qgen which is positive (Pmax = Sbase). For my understand, when Pgen = Pmax = Sbase, it means the generator can't produce any reactive power.
I can't only get the half D-curves. I try to change the power factor, but I can't find how to change it.

Is it possible to get the full D-curves from GUI? Thank you very much.

I try to follow the answer from "How to create a P-Q curve of the solar farm", but I fail to plot the D-curves. Can I ask, to plot the D-Curves, I need to do the Power Flow or Dynamic analysis? Is there any material about how to plot D-Curves? Thank you very much.

There is no "user-defined" plotting in PSSe, only from embedded engines like dynamic simulation and PV or QV engines. Grab the vectors P & Q data and use Excel to plot the D-curve.
