Power system stabilizers (PSSs) are added to excitation system to enhance the damping during low frequency oscillations. This paper presents a study of fuzzy logic power system stabilizer (PSS) for stability enhancement of a single machine power system. In order to accomplish the stability enhancement, speed deviation (Δω) and acceleration (Δπ) of the rotor of synchronous generator of Kota Ther...

Low frequency oscillations (LFO) are a frequent harmful phenomenon which increases the risk of instability for the power system. They limit the steady-state power transfer and change the operational system economics and security. The identification of LFO and solution to LFO problems with reference to power system stabilizer is carried out in this literature survey.

This paper proposes a novel structure of power system stabilizer (PSS) to improve the stability synchronous generators (SGs) in microgrids. Microgrids are relatively vulnerable terms due their small size and low inertia. The rotational inertia voltage support SGs highly suitable for getting over vulnerabilities microgrids, but there exist weaknesses low-frequency oscillations (LFOs) limitations...
