Abstract: The paper illustrates a procedure to develop a dynamic simulation program for a single machine infinite bus (SMIB) test system using MATLAB/Simulink software. The program is useful to demonstrate various operational and stability challenges in power system operations. The method can be extended to make a program to simulate network having multiple synchronous machines, asynchronous ma...

The effect of line impedance compensation mode of series inverter along with the voltage regulation mode of shunt inverter of UPFC is investigated for transient stability improvement of Single Machine Infinite Bus System. Four control modes like perpendicular voltage or phase angle control etc have also been discussed. The effect of line impedance mode on critical clearing time with a three pha...

This paper proposes the energy function of a power system with a Static Synchronous Series Compensator (SSSC). They make it possible for the direct method to acquire the transient stability or critical clearing time assessment of a power system. The proposed energy function of a power system with a SSSC is first derived and then it is used for SSSC control design. The proposed method is tested ...

This article discusses the development of a Power System Stabilizer (PSS) utilizing Virus Particle Swarm Optimization Algorithm (VEPSO) to enhance power system stability. PSS is commonly used in industry suppress oscillations. The proposed algorithm was implemented on Single Machine Infinite Bus (SMIB) system, and controller coefficients were optimized using VEPSO. simulated under specific dist...

Electric power systems are frequently nonlinear and, when faced with increasing power demands, may behave in unpredictable and rather irregular ways. We investigated the nonlinear dynamics of a single machine infinite bus power system model in order to study the appearance of coexistent periodic and chaotic attractors, characterizing multi-stable behavior. The corresponding basins of attraction...

This paper presents a robust nonlinear state feedback linearization approach for power systems with uncertainties. The uncertainties considered here are a class of bounded perturbations to the state model of power systems. The control law is applied through the excitation system of the synchronous generators connected to the power systems to enhance the stability of the system. In this paper, u...
