“…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.

“…To enhance the transient stability of the large units, the fast-response high-gain exciters began being widely applied in the power system, which causes another serious problem, i.e., the low frequency oscillation [1][2][3][4][5][6][7]. Power System Stabilizer (PSS) is an auxiliary excitation control technique in order to eliminate the low frequency oscillation happening in the power system [2][3][4]. Its design theory was well developed during 1960s [3][4][5].…”

“…Power System Stabilizer (PSS) is an auxiliary excitation control technique in order to eliminate the low frequency oscillation happening in the power system [2][3][4]. Its design theory was well developed during 1960s [3][4][5]. Based on this theory, the low frequency oscillation happens because of the weak or even negative damping of the power system in operation.…”

“…To do so, the electro-magnetic torque is decomposed into the synchronous torque component and the damping torque component [4]; then the feedback from either the rotor speed or the electro-magnetic torque or both is used to increase the damping torque component. The key of this step lies in compensating the lag angle between the rotor speed and the electro-magnetic torque [1][2][3][4][5]. By doing so an extra damping torque is appended on the original one.…”

Power System Stabilizer (PSS) was proposed during 1960s to solve the low frequency oscillation problem raised by the wide application of the high-gain fast-response exciters. The fundamentals of PSS design lie in the angle compensation to increase the damping torque, which, since then, has become an important principle in designing the various power system dampers, such as SVC, TCSC, UPFC. Although many papers have been dedicated to the application of this principle, it is interesting to note that in the real industry applications PSS parameters have to be carefully tuned on site in spite of its mature design theory. So does the classical PSS design theory really meet the PSS design demand? By combining the frequency domain and the time domain analysis, this paper reinvestigates the basic idea behind the classical PSS design theory. The paper clarifies the concepts of the synchronous torque as well as the damping torque and proves that the classical PSS design principles based on these concepts are not theoretically sound. Then the paper discusses the Linear Optimal Controller Design method and analyzes its relations with the conventional PID design. By doing so the paper reveals the real mechanism of the PSS and proposes to use more systematic and advanced control tools to enhance the controller performance.power system stabilizer, low frequency oscillation, power system dynamics Citation:
