      abstract     = {Modern societies crucially depend on the robust supply with
                      electric energy so that blackouts of power grids can have
                      far reaching consequences. Typically, large scale blackouts
                      take place after a cascade of failures: the failure of a
                      single infrastructure component, such as a critical
                      transmission line, results in several subsequent failures
                      that spread across large parts of the network. Improving the
                      robustness of a network to prevent such secondary failures
                      is thus key for assuring a reliable power supply. In this
                      article we analyze the nonlocal rerouting of power flows
                      after transmission line failures for a simplified AC power
                      grid model and compare different strategies to improve
                      network robustness. We identify critical links in the grid
                      and compute alternative pathways to quantify the grid's
                      redundant capacity and to find bottlenecks along the
                      pathways. Different strategies are developed and tested to
                      increase transmission capacities to restore stability with
                      respect to transmission line failures. We show that local
                      and nonlocal strategies typically perform alike: one can
                      equally well cure critical links by providing backup
                      capacities locally or by extending the capacities of
                      bottleneck links at remote locations.},
