Resumen:
This paper addresses the allocation of defensive resources in a power system under multiple contingencies. This problem is characterized by a defender-attackerdefender model which is formulated as a trilevel programming problem. In the first level, the system planner identifies the components to be hardened in order to reduce the damage associated with plausible outages. In the second level, the disruptive agent determines the set of out-of-service components so that the damage in the system is maximized. Finally, in the third level, the system operator minimizes the damage caused by the outages selected by the disruptive agent by means of an optimal operation of the power system. We propose a novel two-stage solution approach that attains optimality with moderate computational effort. The original trilevel program is first transformed into an equivalent bilevel program, which is subsequently solved by an efficient implicit enumeration algorithm. The effectiveness of the proposed methodology is validated on the IEEE Reliability Test System.
