Hello everyone, im trying to retrieve both load data and generation data when running dymanics. And the code is running in increments with accordance to time delay. So every 0.017 seconds, it outputs generation and load. My load data retrieval is working in that the load is changing with response to tripped lines in the system. My generation stays constant which should not be the case. Anyway to retrieve generation in response to time in dynamics, is there any API out there and I want it so i can look at every generator in a particular area of the system instead of pre definig each generator.

    [ierr, rval_C] = psspy.chnval(GL_C)
    [ierr, rval_L] = psspy.chnval(GL_L)
    C_freq = 60*(1 + rval_C)
    L_freq = 60*(1 + rval_L)
    [ierr, sysload_LI = psspy.ardat(#, 'LOAD')
    [ierr, sysload_N] = psspy.ardat(#, 'LOAD')
    [ierr, sysload_D] = psspy.ardat(#, 'LOAD')
    [ierr, sysgen_N] = psspy.ardat(#, 'GEN')
    [ierr, sysgen_L] = psspy.ardat(#, 'GEN')
    sysgen_TOT = sysgen_N.real+sysgen_L.real
    sysload_TOT = sysload_N.real+sysload_D.real+sysload_L.real


    my_print(print_file, 'TIME NOW: {:.3f} SEC       FREQ (HZ): [ {:.2f} IN C      {:.2f} IN L      {:.2f} GENERATION ]       LOAD (MW): [ {:.2f} ]'  , [tm_runto, C_freq, L_freq, sysgen_TOT, sysload_TOT])

Use CHSB to add channels with area totals. Then use chnval to extract the load and gen values for each area of interest.
