Dynamic Stability of SMIB System with Fuzzy Logic Based Power System Stabilizer

This paper studies Dynamic Analysis and Stability of Single machine connected to infinite bus (SMIB) with power system stabilizer (PSS) in presence of Fuzzy logic controller (FLC). Here PSS is modeled using fuzzy logic controller and the response is compared with the responses of the system in presence of conventional PI, PID controllers. In case of FLC, different membership functions are studied and all responses are compared. Finally the fuzzy logic based PSS with Gauss and triangular membership functions give better performance. Matlab-Simulink is used to test the results.
