This paper considers the stabilization of a synchronous machine connected to an infinite bus via a PID. The PID parameters are tuned using hybrid Particle Swarm-Bacteria Foraging Optimization (PSO-BFA). Simulation results are introduced with and without the proposed controller. Also, a comparison study is introduced when using classical PID, only bacteria foraging optimization and when using hy...

Small-signal instability of grid-connected power converters may arise when the use phase-locked loops (PLLs) to synchronize with a weak grid, i.e., operating in grid-following mode. Commonly, this stability problem (referred as PLL-synchronization paper) was studied by employing single-converter system connected an infinite bus, which, however, omits impacts grid structure and interactions amon...

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...

Changes in the load on electric power system suddenly cause dynamic disturbances. The disturbance causes stability of generator to be disturbed, because does not respond quickly. This oscillations form frequency and rotor angle. One additional control equipment that can increase a is Power System Stabilizer (PSS). With PSS installation, optimal response angle SMIB are obtained, indicated by min...

This paper presents the sensitivity analysis of the behavior of a synchronous machine using the winding function theory considering the effect of static air-gap eccentricity. The winding function theory as a method to calculate the inductances of synchronous machines from the geometry and the actual arranging of the windings is presented. Then, detailed numerical simulations are carried out to ...
