Transient Stability Analysis of the Transmission System Considering the Initial Steady State Results

In modern power systems, nonlinear power system stability under normal conditions depends on the magnitude of disturbances and the initial conditions. In other words, after a disturbance occurs in the power system, the system stability is determined by the observation of voltage, frequency and rotor angle. Transient stability examines the impact of disturbances on power systems considering the operating conditions. The analysis of the dynamic behavior of power systems for the transient stability gives information about the ability of a power system to sustain synchronism during and after the disturbances. In this paper, the transient stability of the IEEE-9- bus modified test system is analyzed with Matpower and PowerWorld software under a 3-phase balanced short-circuit.
