In PLNTBU1 there are two output signal, Wext and Pext which are the inputs in the two REAX4BU1 which are modelled.

When I have REPCA PPC, I modified Vref or Pref in order to get a change in the voltage or active power repectively. In the PLNTBU1, to get a voltage step at control bus, should Vref be modified? And to have a change in Pref should Plantpref be modified? When I changed Vref I can see an voltage step at POI whereas a change in Plantpref does not change anything.

What are AUX VAR used for? Are they linked to the Auxiliary-signal models (CHAAUT, CPAAUT, etc...) I don't have?

In REAX4BU1 there are wref1 and pref1? How are these vars calculated? Is something I can change?

i am performing MNOD26 and 27, and usually I modified kp, kpg, ki and kig. In this case, in PLNTBU1 I suppose the same k should be modified. But in REAX4BU1, can kw1 and kp1 be modified?

Hello there, the output of PLNTBU1 will go to REAX4BU1 Controller. In addition you can also modify the the value kw1 &kp1 similar with (1%-5%) droop on rating capacity concept
