In theory, the DSTATE value should be zero, but in practice, a very small value is workable. I supplement the "initial conditions suspect" table listing with the plotting/evaluation of channels (Pe,Qe,..) after a dynamic simulation under no disturbance for the period of interest (a flatstart for 10 sec.?) An acceptable response would be a flat line with max. deviations smaller than 10e-2. Use PSSPLT to evaluate max. deviations. If the plot has larger deviations or oscillations, model parameters need adjustments.
