Dieser Index kann f\u00fcr Verfahren aus der Schaltungssimulation bei speziellen Anforderungen an die Betriebsmittelmodelle und die Topologie a priori bestimmt werden. Die Ergebnisse aus der Schaltungssimulation sollen auf das in der elektrischen Energietechnik eingesetzte Erweiterte Knotenpunktverfahren \u00fcbertragen werden. Dazu wird eine Strukturanalyse des mit dem Erweiterten Knotenpunktverfahren formulierten Differential-algebraischen Gleichungssystems durchgef\u00fchrt.
