Abstract: “The study of multi-machine transient stability in a large interconnected power system requires a lot of computational time. To reduce the computational time, a model of real-time of transient stability simulation method is employed in power systems. Application in transient stability provides very quick insight into the behavior of the generators under a threephase fault. The objective of this paper is accelerating computation time. The requirement is a computationally efficient way of processing on line to determine whether an evolving event will ultimately be stable or unstable. The proposed optimal power flow on transient stability model will be tested and analyzed using an illustrative the IEEE Western System Coordinating Council (WSCC) 3-machines 9-bus test system.”
