In recent years, the penetration of renewable resources in electrical power systems has increased. These renewable resources add more complexities to power system operations, due to their intermittent nature. As a result, operators must acquire additional reserves in order to maintain reliability. However, one persistent challenge is to determine the optimal location and quantity of reserves; this challenge is exacerbated by the inability to predict key transmission bottlenecks due to this added uncertainty. This paper presents robust corrective topology control, as a congestion management tool, to reduce violations caused by contingencies and renewable uncertainties. The day-ahead topology control formulation is based on the direct current optimal power flow; therefore, switching solutions obtained from these algorithms are tested for AC feasibility and system stability. All numerical results are based on the IEEE-118 bus test case.
