Modeling Coupled Nonlinear Multilayered Dynamics: Cyber Attack and Disruption of an Electric Grid

Figure 10

(a) Risk to the grid from compromise is determined by the increase in demanded power per-compromised AMI, , the critical value at which the grid becomes unstable when demanded power is , and the level of compromise at the time of detection of compromise. We show risk to the grid over a range of values of for (solid, large dashed, and small dashed lines, respectively) (b) Expansion of the lower corner of (a).
