Abstract

It is widely known that corrective switching, including transmission line switching 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 transient stability of power systems. In this paper, based on the Newton-Raphson sensitivities and the sparse inverse technique, a new power compensation model (PCM) for line and bus-bar switching is proposed to simulate complicated and multiple line switching actions and bus-bar switching actions. Then a binary integer programming (BIP) based optimal power flow (OPF) algorithm is developed to find the best line and bus-bar switching action for relieving overloads and voltage violations caused by system contingencies. Simulation results on the WECC 179-bus system indicate that the new algorithm proposed in this paper can effectively solve certain problems of line overloads and voltage violations and significantly reduce the computational time.
