Abstract

The Security-Constrained Optimal Transmission Switching problem consists of finding a cost-efficient generator and topology configuration for a power network. Considering the size of the considered networks as well as the large number of scenarios (contingencies) and different topologies, we show how to employ Benders decomposition to solve the problem. We describe acceleration techniques such as partial subproblem solving, cut selection and primal heuristics. Additionally, we present a nested Benders decomposition approach for the problem. Preliminary computational results indicate major performance improvements with the proposed enhancements.
