Analysis of Cascading Failures in Small-world Power Grid

The development of complex network theory, especially the discovery of small-world characteristics in power grids, has made people more and more concerned on the structural vulnerability of electric power system. On the basis of complex network theory, this paper studies the heterogeneity of small-world power grid, specially analyzes the inherent reason for cascading failures in small-world power grid and looks for valid measures to improve the capability of the power grid to endure large-scale blackouts. Failure simulations have been done on topological models of Anhui power grid and the East China power grid. The results show that structural vulnerability of small-world power grid is the intrinsic reason for failures to cascade in the grid and external factor can hardly improve its endurance to large-scale cascading failures. Meanwhile, strategies to prevent large-scale cascading failures are presented and tested, and it is found that more reasonable resource configuration and load distribution are meaningful to increase the reliability of electricity transmission.
