Reconfiguration of transmission systems with transient stability constraints

This paper focuses on theoretically proposing a method based on the decomposition technique to solve the optimal reconfiguration of transmission systems (ORTS) constrained by the transient stability restrictions. The authors first adopt the Benders decomposition to divide the ORTS into an OPF subproblem with the stability constraints and a line switching master problem, by exploiting the characteristics of ORTS. Then, the active set technique is used to improve the efficiency for the subproblem while relaxation method is applied to the master problem to deal with mixed integer variables. Since the ORTS directly involves the manipulations of transmission lines, it can be expected to apply to not only operations of power systems, but also the evaluations of transactions and wheeling under competitive environment
