Using the Single Machine Infinite Bus Power System Model to Design Power System Stabilizers

Since they limit the amount of power that can be transferred through power systems, low-frequency oscillations in power systems (0.1-2 Hz) that are insufficiently damped have been a source of concern for power engineers for a very long time. These badly damped oscillations have an impact on the stability of the power systems as well and can cause instability. The study offers a PSS architecture that will increase power system stability and power transfer efficiency. Lead-lag PSS structure is taken into account in a dynamic MATLAB model created for a power system. To adjust the PSS settings, a damping torque approach is used. By using eigenvalue analysis and time-domain simulations, the outcomes of this method have been confirmed. The created MATLAB model was interfaced with the PIC controller using the peripheral interface controller (PIC) digital controller type. The simulation results demonstrate that using the developed PSS, system time responses are well-damped under various operating situations.
