Analysis of single machine infinite bus system is made by considering single Kaplan turbine-generator with exciter and governor for the small-signal stability. In this research paper a scientific approach was adopted to minimize the settling time along with the stability of the given power system. Kaplan turbine generators were predominantly implemented in hydroelectric power plants with lower heads. However, dual regulation of such turbines in the plants are renowned in the current research trends. The dual regulation of hydro-turbine is incorporated through the operation of both wicket gate and runner blade position. In a worldwide scenario Kaplan turbine-generators play a vital role in power and energy generation. Whereas the life of these generator gates or runner blades depends on speed deviations. In this context, a PID controller has been designed for the extended single machine infinite bus system to improve the speed deviation. The results of the extended single machine infinite bus system are compared with and without PID controller for the enhancement of speed deviation.

“…Liu et al [6] suggested a continuing fraction-based method for online simulation and control of power systems using SMIB. Bux et al [7] examined the damping efect of the VSC stabilizer and its infuence on electromechanical oscillation modes. To compensate for parameter sensitivity in SMIB, Roy et al [8] integrated feedback linearization with adaptive control.…”

To improve power quality in power systems vulnerable to current disturbances and unbalanced loads, a hybrid control scheme is proposed in the present paper. A hybrid adaptive robust control strategy is devised for an SMIB power system equipped with a static VAR compensator to ensure robust transient stability and voltage regulation (SVC). High-order sliding mode control is combined with a dynamic adaptive backstepping algorithm to form the basis of this technique. To create controllers amenable to practical implementation, this method uses a high-order SMIB-SVC model and introduces dynamic constraints, in contrast to prior approaches. Improved transient and steady-state performances of the turbine steam-valve system are the goals of the dynamic backstepping controller. A Lyapunov-based adaptation law is developed to address the ubiquitous occurrence of parametric and nonparametric uncertainty in electrical power transmission systems due to the damping coefficient, unmodeled dynamics, and external disturbance. High-order sliding mode (HOSM) control is used for generator excitation and SVC devices to construct finite-time controllers. The necessary derivatives for HOSM control are calculated using high-order numerical differentiators to prevent simulation instability and convergence issues. Simulations demonstrate that the suggested method outperforms conventionally coordinated and hybrid adaptive control schemes regarding actuation efficiency and stability.
