Objectives: Fuzzy logic controller based IDVR in IEEE 30 bus system for voltage sag compensation is proposed in this paper. Methods/Analysis: Closed loop control technique (PI, PID, FOPID and FUZZY) is implemented to analysis the dynamic perform of the system. Measurable parameters such as steady state error, peak time, and rise time, settling time and voltage profile of above controllers are simulated and compared using MATLAB/SIMULINK. Findings: The comparison results reveal that, a time domain specification is improved and steady state error is decreased. Novelty/Improvements: FUZZY logic based IDVR system has been implemented to improve the dynamic performance of the system.
