Abstract – Superconducting magnetic energy storage with the fuel cell (hybrid system) is possessed by its high efficiency storage of energy which is expected to contributing of high quality power in power systems. SMES has ability for real power storage with high power and energy density. This SMES characteristics is used for protecting consumers from the grid voltage fluctuations. They are voltage sag, voltage swell and interruptions. This paper analyze the operational principle of SMES with fuel cell based DVR. It is designed by using fuzzy logic control for the compensation of grid voltage fluctuations. This model is established using MATLAB/SIMULINK and the system performance is evaluated by simulation tests.
