“…1). The control schemes of synchronous machines are commonly based on a reduced-order linearized model and classical control algorithms that ensure asymptotic stability of the equilibrium point under small perturbations [1], [2]. Recently, to overcome the limitation of linear control, attention has been focused on implementation of modern control technique, e.g., an adaptive linear control [3]- [6], passivity-based approach [7]- [10], intelligent control such as fuzzy logic [11]- [13] and neural networks [14], control based on direct Lyapunov method [15], [16], feedback linearization (FL) technique [17]- [21], and control based on adaptive FL [22], [23].…”

Based on the complete model of the plant, a sliding-mode stabilizing controller for synchronous generators is designed. The block control approach is used in order to derive a nonlinear sliding surface, on which the mechanical dynamics are linearized. This combined approach enables us to compensate the inherent nonlinearities of the generator and to reject high-level external disturbances. A nonlinear observer is designed for estimation of the rotor fluxes and mechanical torque.

“…Several approaches have reported in the literature to provide the required damping torque for improving the dynamic stability. One of the approaches is conventional power system stabilizer a lead/lag network using the speed or power as input to generate an additional stabilizing signal [4][5][6] is employed and its parameters were designed by using different techniques, another is to employ a linear optimal stabilizer using the theory of linear optimal regulators [7][8][9][10][11][12] and so on.…”

To improve the dynamic stability of power systems, by increasing the damping torque of the synchronous machine, it is necessary to use the power system stabilizers to enhance the damping during low frequency oscillations. In this article, an attempt has been made to design the parameters of power system stabilizer by using the Firefly Algorithm applied to the single machine infinite bus system to an amenable form. The stability enhancement has been compared with Genetic Algorithm stabilizer for different operating conditions. The results show that the designed power system stabilizer based on Firefly Algorithm gives a good dynamic response when compared to Genetic Algorithm power system stabilizer. The Pseudo Spectrum analysis is also presented which is evident about the enhanced stability of the system with the proposed Algorithm.

Abstract-This paper demonstrates the robust tuning of power systems stabilizers for power systems, operating at different loading conditions. A classical lead-lag power system stabilizer is used to demonstrate the technique. The problem of selecting the stabilizer parameters is converted to a simple optimization problem with an eigenvalue-based objective function, which is solved by a tabu search algorithm. The objective function allows the selection of the stabilizer parameters to optimally place the closed-loop eigenvalues in the left-hand side of a vertical line in the complex -plane. The effectiveness of the stabilizers tuned using the suggested technique, in enhancing the stability of power systems, is confirmed through eigenvalue analysis and simulation results.
