Evaluating North American Electric Grid Reliability Using the Barabasi-Albert Network Model

Abstract

The reliability of electric transmission systems is examined using a scale-free model of network structure and failure propagation. The topologies of the North American eastern and western electric networks are analyzed to estimate their reliability based on the Barabasi-Albert network model. A commonly used power system reliability index is computed using a simple failure propagation model. The results are compared to the values of power system reliability indices previously obtained using standard power system reliability analysis methods, and they suggest that scale-free network models are useful for estimating aggregate electric network reliability.
