Abstract

With the method of modal analysis, the full Jacobian according to the power system power flow equations is studied and a method to identify the suitable bus for loading shedding is proposed in this paper. The proposed method makes use of the participation factors corresponding to the active power, by which the structural characteristic of the power system nonlinearity is included. As a result, the effective bus where the load shedding should be used can be found. In order to show the effectiveness of the proposed method, the WSCC 9-bus power system is used as an example. The simulation results indicate that with the load shedding at the place where the proposed method decided, the voltage stability indices are considerably increased. The proposed method in this paper is effective.
