The advanced electric power grid: Complexity reduction techniques for reliability modeling

Abstract

The power grid is a large system, and analyzing its reliability is computationally intensive, rendering conventional methods ineffective. This paper proposes techniques for reducing the complexity of representations of the grid, resulting in a mathematically tractable problem to which our previously developed reliability analysis techniques can be applied. The IEEE118 bus system is analyzed as an example, incorporating cascading failure scenarios reported in the literature. © 2008 Springer-Verlag Berlin Heidelberg.
