Abstract

It is widely known that corrective switching (including transmission line and bus-bar switching) may change the states of the power systems, and consequently, affect the distribution of power flows, transmission losses, short circuit currents, voltage profiles as well as the transient stability of power systems. In this paper, based on the fast decoupled power flow (FDPF) with limited iteration count, a new algorithm is developed to find the best line and bus-bar switching action for relieving overloads and voltage violations caused by system faults. A general model of bus-bar switching action is proposed such that the new algorithm can simulate any kind of complicated bus-bar switching action. Simulation results on the 39-bus New England system show that the new algorithm proposed in this paper can effectively solve the overload and voltage violation problems and the computation time is also satisfactory.
