    Transmission line switching is an important operational action in power transmission systems, and has been successfully applied to reduce generation costs and eliminate congestions. Prior work mainly focus on tackling the Optimal Transmission Switching problem based on steady states. This paper studies how to generalize these results when transmission switching is performed on highly congested systems. It proposes an optimization model to find the optimal line to switch and the corresponding optimal control parameters. The results show that optimizing the exciter and stabilizer control settings is critical to ensure stability and the optimization model can be solved within a few minutes. The model was validated with respect to a simulation model and is shown to an accuracy in the order of 103 (deg) accurate in rotor angle computations.
