In this paper, we propose an energy-based method for the transient stability\nanalysis of a power system transmission switching event. In this method the\nexit point of pseudo-fault trajectory is used to determine a relevant\ncontrolling unstable equilibrium point (CUEP) for a switching event, the\nstability of the switching event is then assessed based on the energy margin\nbetween the computed relevant CUEP and the post-switching initial point. The\neffectiveness of the method is demonstrated on switching events in the\nstructure-preserving models of a heavily loaded version of the WSCC 9-bus\n3-machine system, and the base case IEEE 145-bus 50-machine system. A scheme\nfor the detailed analysis of power system switching events is then proposed.\n
