Fuzzy Logic Based Islanding Detection Technique for Integrated AC and DC Microgrid System

Abstract

This research introduces a fuzzy logic-based approach for detecting islanding in an integrated AC to DC microgrid system. Existing power management systems often face limitations related to power sharing and voltage regulation in interlinked micro grids, especially when specific loading conditions are not considered.  To tackle these challenges, an independent integrated power management scheme has been implemented. This scheme evaluates unique loading conditions before importing power to   mitigate these challenges; the proposed approach focuses on interlinking the AC microgrid, thereby reducing the operational converters during the voltage regulation process in the DC microgrid. This strategy aims to enhance the overall efficiency of the system. designed to be fully autonomous, particularly catering to plug-and-play functionalities. Specifically designed for generators and tie-converters, the proposed approach caters to the unique requirements and functionalities of these components. Validation of the scheme is carried out through various scenarios, confirming its effectiveness in managing power and maintaining superior control of voltage.
