A hybrid approach using Monte-Carlo simulation and an enumeration technique for the reliability evaluation of large scale composite generation-transmission systems is presented. The method is suited to the analysis of large systems and can be used to include multi-state representation of generating units. Studies presented illustrate that derating-adjusted two-state models for generating units can lead to pessimistic appraisals of composite system adequacy. Variability in system load can be incorporated by using a chronological load representation or by an aggregated load model. The accuracy of the load representation and the required computation time increases with the utilisation of more steps in the annual load duration curve
