Analysis And Improvement of The Transient Power System Stability Using DFACT devices and Cusp of Catastrophe Theory

Abstract

power systems Transient stability relate to the maintain of system ability  to temporal relation when subjected to a intense  perturbation of transient like a load changes, fault, sudden loss of generation. The dynamic of the system makes analysis challenging of transient power system stability. Catastrophe theory, focus of attention the sensitive dependence of nonlinear systems on initial conditions small disturbance possible to cause large variable in behavior of system stability. This generalization can be supplement to transient stability improvement by dominant system trajectories away from instability. This manuscript introduces a comprehensive analysis of transient power system stability improvement using Catastrophe Theory and Distributed Flexible AC Transmission System (D-FACTS) devices. The work distinctness on enhancement of the system stability during large perturbation by predicting instability using Catastrophe Theory and kinetic controlling power flows using D-FACTS devices.A demonstration of the suggested analysis of the New England 39-bus power system using power world simulator is provided to confirm that effectiveness
