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. However, existing control schemes exhibit critical shortcomings that limit their practical effectiveness. . In this paper, we study the modeling, the control, and the power management strategy of a grid-connected hybrid alternating/direct current (AC/DC) microgrid based on a wind turbine generation system using a doubly fed induction generator, a photovoltaic generation system, and storage elements. . Hybrid AC–DC microgrid systems have recently emerged as a promising method for connecting AC loads with AC microgrid (ACM) and DC loads with DC microgrid (DCM). It is of great significance and value to design a reasonable power coordination control strategy to maintain the power balance of the system.
