Multi-machine power system fuzzy stabilizer design using Cuckoo search algorithm

Nowadays, fuzzy controllers have achieved an important role in different systems and their superiority over the classical control methods has been proved. In this study, the power system stabilizer is used to damp the power system oscillations based on the fuzzy logic controller. A three-phase to ground-fault test is done during a period of 10 ms to evaluate power system behaviour between the area of two distinct points. Simulation results show that the system is unstable without a stabilizer. It has also been determined that the fuzzy stabilizers have high ability to damp the system oscillations in comparison with classical stabilizers so that system oscillations are damped with higher speed and lower amplitude. Also in this study, the Cuckoo search algorithm is used to optimize the fuzzy stabilizer inputs and improve its performance. The results show that the optimizations of stabilizer parameters improve their damping performance.
