Optimal Transmission Switching (OTS) has demonstrated significant savings potential on test systems when formulated in a linearized DC power flow framework. However, OTS solutions generated from DC models have no feasibility guarantee when applied to AC power flow models. Additionally, AC-feasible OTS solutions may not generate cost savings as suggested in the DC model. We present a method to correct OTS solutions obtained in the DC model to ensure feasible AC power flow solutions. When applied to the RTS-96 benchmark network, the method achieves results that are both AC feasible and generate significant system cost reductions.
