This paper provides a comprehensive review of recent robust control strategies for hybrid AC/DC microgrids, systematically categorizing classical model-based, intelligent, and adaptive approaches. . Hybrid AC/DC microgrids have emerged as a promising solution for integrating diverse renewable energy sources, enhancing efficiency, and strengthening resilience in modern power systems. Besides, the lack of inertia caused by droop and phase-locked loop-based current control brings negative effects to the system. We propose a distributed normalized power coordination. . Abstract: This paper describes a hybrid ac/dc micro grid that may be used to decrease the procedures of many dc-ac-dc or ac-dc-ac conversions in a single ac or dc grid. The hybrid grid is made up of both alternating current and direct current networks that are linked together by multi-bidirectional. . This paper presents a distributed control architecture for voltage and frequency stabilization in AC islanded microgrids. In the primary control layer, each generation unit is equipped with a local controller acting on the corresponding voltage-source converter.

Peer-to-peer mode • Peer-to-peer mode is a control strategy based on ideas of “plug-and-play” and “peer-to-peer” used in power electronic technologies. . The document discusses three control modes of micro grids: master-slave mode, peer-to-peer mode, and combined mode. In master-slave mode, certain distributed generators (DGs) serve as master units while others act as slaves, with different operational controls for grid-connected and islanded. . Microgrids as the main building blocks of smart grids are small scale power systems that facilitate the effective integration of distributed energy resources (DERs). In normal operation, the microgrid is connected to the main grid.
