I have a question in regard to writing a script for a UDM PPC in PSSE.
I am trying to establish a communication between a UDM PCC that I am modeling as a renewable machine plant control and a generic electric model in PSSE by using a REECCU1 and REGCA1. I am using the following in Fortran for PSSE35: In mode 3:

        CALL WINDMIND(NUMBUS(IB),'1','WELEC','VAR',LREEC,IERR) !WINDMIND
        MC = WNDNUM(I)
        WQCMND(MC) = VOUTQ
        WPCMND(MC) = VOUTP

and in mode 1: CALL WINDMIND(NUMBUS(IB),'1','WELEC','VAR',LREEC,IERR) !WINDMIND MC = WNDNUM(I) VOUTQ = WQCMND(MC) VOUTP = WPCMND(MC)

i am getting initial conditions dstate suspect from the generator and electric model. Parameters are not transferred to the electric model still. So I have my VARs in my PCC stay zero after a dynamic simulation. I think the syntax is wrong, and the PSSE manual was not clear in this regard. thanks!
