MicrogridStability Enhancement by using Coordination of SFCL, SMES and Distributed Generation Units with Fuzzy Logic Controller

By the coordination of the superconducting fault current limiter (SFCL), superconducting magnetic energy storage (SMES) and distributed generation (DG) unit. The stability of the micro grid can be increased under short circuit fault condition. From this coordination control, the micro grid is smoothly separated from the main network under severe fault and attains a fault ride through (FRT) operation under minor fault. In this paper, fuzzy logic controller is used in SFCL in place of PI controller to reduce the frequency fluctuations and fault currents in order to improve the stability of the grid. This results are obtained by using the MATLAB/Simulink.
