“…Some application of intelligent control such as: Adaptive neuro-fuzzy inference system (ANFIS) model for enhancement of power system stability [12], transient response improvement of rectifier in high voltage direct current [13]. Stability effect of rotary-frequency based converter is implemented as the PSS in 50/60 Hz PS [14]. The Interval type-2 fuzzy is a linguistic model that is used in wide range such as power system stabilizer to improve stability of single machine [15], multi machine [16] and large-scale PS [17].…”

Interval type-2 fuzzy (IT2F) model develops to substitute conventional control in power system (PS). The PS is operated to serve the consumer according to load demand. Load fluctuation on the PS is a real situation and can't be avoided. The load fluctuation causes rotor oscillation on machine. Moreover, instability problem can occur if this oscillation is not quickly to damp. The IT2F-based algorithm is developed to replace conventional power system stabilizer (PSS) function. The IT2F is implemented in this research because it simple and not need exactly calculation of plant model. A single machine and multi-machine power systems are applied to assess the performance of the IT2F-PSS. This IT2F-PSS is constructed by two inputs and an output. Three membership functions (MF) Gauss-2 type are used for respective inputs. Five MFs constant type are used for output. The values of fuzzy parameter are tuned properly based on the knowledge and experience the fuzzy developer. Simulations on the case studies provide enhancement the response of rotors speed and angle. The IT2F-PSS responses are assessed on peak overshoot and settling time.

“…Generator excitation control can not only enhance the power system static stability limit, but also attenuate low-frequency electromechanical oscillations inherent to power systems, during transient conditions (Bazanella & Conceic -ão, 2004;Damm, Marino, & LamnabhiLagarrigue, 2004;Maya-Ortiz & Espinosa-Pé rez, 2004;Sae-Kok, Yokoyama, Verma, & Ogawa, 2006). Since excitation control is restrained by excitation current ceiling, the requirement of generator possessing excess of excitation current ceiling will increase its manufacturing cost (Lu & Sun, 1993).…”

“…Therefore it is a very active area of research (Bazanellan and Conceic, 2004;Paul and Gerardo, 2004;Sae-Kok et al, 2006). Since excitation control is retained by excitation current ceiling, the requirement of generator possessing excess of excitation current ceiling will increase its manufacturing cost.…”

Transient stability problem for a single machine infinite bus system with the generator excitation and thyristor controlled series compensation when damping coefficients are measured inaccurately is investigated. A robust coordinated passivation controller is designed to achieve the stability of the rotor angle and speed. The excitation voltage control is obtained by means of adaptive back-stepping method and Lyapunov stability theory using a fourthorder two-input nonlinear model. A parameter updating law is obtained simultaneously, and the reactance modulated input is derived via the coordinated passivation approach. This way the feedback passivity of the overall system is achieved and the closed-loop system is made asymptotically stable. Simulation results for a given example of the SIMB benchmark case demonstrate the effectiveness of the proposed design.
