In my opinion is is a bad practice to initialise several times to get rid of initial condition suspect. This will lead to a different starting point for the voltages, currents and flows than the load flow solution. Also running to x seconds will lead to a different starting point.
Instead, the root of the problem should be corrected. See post Question for initial condition suspect.
Initial condition suspect is caused be at least one dynamic model with limitations that will prevent the model to be initialised to the same conditions as in the solved load flow. It may be caused by e.g. an exciter model, governor model, renewable model, SWS model, FACTS model, HDDC model, etc. Problem with one model may cause hundreds of DSTATE problems in a large part of the network. Look for the models with large DSTATEs.
