Design of Modified Maiden Power System Stabilizer Using Cuckoo Search Algorithm

Abstract

This article presents an improved maiden power system stabilizer (PSS) for enhancement of small signal stability of a power system. The free coefficients of proposed PSS are determined using optimization technique with the cuckoo search algorithms (CS-PSS). The performance of the CS-PSS is validated on single-machine infinite-bus power and extended to a multi-machine power system. These results are compared to the newly introduced maiden PSS structure and found superior in terms of settling time and performance indices.
