Power System Stabilizer design using fuzzy logic for SMIB system

What is it about?

A fuzzy logic control design is proposed as a means of enhancing the stability of the power system. A Single Machine Infinite Bus (SMIB) power system is studied with the use of a fuzzy logic power system stabilizer (PSS) controller. A synchronous generator’s controllers are controlled by speed deviations and rotor accelerations, which are integral to maintaining the system’s stability. An implementation of fuzzy logic can provide a more consistent and reliable supply of power, thereby stabilizing the power system.

Why is it important?

Disturbances are a recurring issue in power systems. Nevertheless, our system remains stable as extra signals are injected into the voltage regulators to prevent an unstable mode. Different factors like speed deviation, excitation deviation, and accelerating power produce the signals that are utilized in the power system. In order to keep the power system stable, these signals are crucial. These signals are generated by specially designed devices called power system stabilizers (PSS) during power outages.
