Effect of bus load uncertainty and correlation in composite system adequacy evaluation

A tabulating technique of normal distribution sampling is used to simulate bus load uncertainty and a correlation sampling technique is utilized to simulate bus load correlation including those situations in which bus loads are completely dependent or independent. These techniques have been incorporated in the MECORE computer program developed at the University of Saskatchewan for composite system reliability evaluation. Case studies include comparisons between the normal distribution sampling technique and a discrete interval enumeration model, effects of bus load uncertainty and correlation on annualized and annual indices for different systems, and effects of different load uncertainty standard deviations and different degrees of bus load correlation on the inadequacy indices.<
