Figure 1: Basin stability of the generator in the one-node model. Full size image. Figure 2: Relation between basin stability and topological properties of a node. Figure 3: Effects of dead ends and dead trees. Figure 4: Northern European power grid. Discussion We have investigated the stability of power grids by means of a component-wise version of basin stability, a method that has not been used before and, we believe, might also benefit investigations into other multicomponent systems, including ecosystems 25 , food webs 26 and gene regulatory networks 27 , Methods Power grid model Power grids are vast, highly complex machines and one usually focusses on the aspects most relevant for the problem to be addressed instead of modelling every detail as accurately as possible 5.
