Abstract
In order to analyze the invulnerability of complex power grid under extreme weather conditions, this paper proposed an outage probability model for the power grid nodes, with the consideration of typhoon and derived disasters. Furthermore, a cascading fault model based on complex network theory was proposed in this paper. With the consideration of the power grid node breakdowns resulted from the extreme weather and the node overload failure in the cascading failures, the invulnerability of complex power grid was analyzed using the method of cascading fault simulation. Moreover, Guangdong power grid was taken as an example to indicate that the small-world property of power grid was the inner reason resulting in the reduction of invulnerability.Then, the cascading fault simulation results fully showed that the more small-world property might exacerbate the reduction of power grid invulnerability. Finally, it was pointed out that extreme weather can expand the propagation range of cascading faults and seriously reduce the invulnerability of power grid.
