Fig. 5: Reduction of large outage probability that can be reached by hardening power lines according to the priority index: comparison of co-evolution and static model.
From: Increasing the resilience of the Texas power grid against extreme storms by hardening critical lines
a, The 20 lines of the Texas power grid with the highest priority index (equation (4)) obtained from the static model (orange lines), the co-evolution model (blue lines) and both models (green lines). b, Detail enlargement (black rectangle in a) of Houston and Harris County, which contain most of the critical lines. c, Power outage distributions of Hurricane Harvey as a function of the number of protected critical lines, as obtained by the co-evolution model (blue) and the static (orange) model. d, Relative reduction of the probability of large power outages as a function of protected lines as obtained from the static model (lines) and the co-evolution model (dots) for the three hurricanes Harvey (blue), Ike (orange) and Claudette (green).
