was able to figure out a way to retrieve the machine output by using the powerflow model "amachreal" API. It will work only if we return PSSE to powerflow mode from the dynamics mode. Following code will help you to understand this logic.

psspy.run(0, t, 0, 24, 0)

psspy.powerflowmode()

ierr, rarray = psspy.amachreal(0, 4, 'PGEN')

df_mach[i] = rarray[0]

i += 1

t += 0.1

psspy.dynamicsmode()

Thank you so much.

I have tried using agenbusreal and amachreal APIs to get the machine outputs for each time steps but it is not working. I was wondering if there is an easy approach to get the machines data without assigning channel to each individual machine. My code is as follows:

while t <= 30:
    psspy.run(0, t, 0, 24, 0)
    ierr, rarray = psspy.agenbusreal(0, 4, 'PGEN')
    #ierr, rarray = psspy.amachreal(0, 4, 'PGEN')
    df_mach[i] = rarray[0]
    # pgen_array.append(rarray[0])
    i += 1
    t += 0.1
