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.

Microgrid control systems: typically, microgrids are managed through a central controller that coordinates distributed energy resources, balances electrical loads, and is responsible for disconnection and reconnection of the microgrid to the main grid. It can connect and disconnect from the grid to operate in grid-connected or island mode. This system integrates diverse power sources, such as solar arrays, wind turbines, and battery storage, collectively known as Distributed Energy Resources (DERs). It also includes the functions of the microgrid energy management. . By incorporating renewable energy sources, energy storage systems, and advanced control systems, microgrids help to reduce dependence on fossil fuels and promote the use of clean and sustainable energy sources. This not only helps to mitigate greenhouse gas emissions and reduce the impact of. .

The power supply for a flywheel energy storage motor is predominantly a variable frequency drive (VFD) or a direct current (DC) power source, 2. The connection type can vary based on system design and operational demands, 3. Electrical energy is thus converted to kinetic energy for storage. When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the. . Flywheel energy storage technologies provide reliable backup power with many attractive features compared with conventional battery technologies. tied to operate at the grid frequency.
