Abstract: Several operational drawbacks for interlinked AC-DC microgrids to the existing schemes of power management. Designed with main objective on based of their loading conditions power sharing among interlinked microgrids for some existing control schemes, while other schemes without considering specific loading conditions of the interlinked microgrids to regulate voltage. However, cannot reach the existing schemes both objectives successfully. To control these problems an autonomous power management for interlinked AC-DC microgrids by fuzzy based tie-converters is proposed. Fuzzy is the advanced controller that will be used in tie converters. By replacing PI with Fuzzy Logic Controller better results will be found. It makes fuzzy logic an effective tool for the conception and design of intelligent systems. The fuzzy logic toolbox is easy to master and convenient to use. The hybrid control has been proposed for the interlinking or tie-converters of the AC-DC microgrids for autonomous power management with FLC. The proposed is fully autonomous scheme, while for tie-converters and generators it retains plug-n-play features. Under different operating scenarios the performance has been validated for the proposed control scheme with FLC. Better voltage regulation maintaining autonomously in the DC microgrid managing the power deficit effectively can be done through proposed scheme. To demonstrate its effectiveness, the system is modelled, and its performance will simulated on MATLAB.
