Abstract. Distributed wind-hybrid microgrids have the potential to provide key resilience and economic benefits to both the customers they serve and the utility grids they are connected to. Such microgrids will likely be a key part of the grid of the future, whether connected to large utility grids or linked together in multi-microgrid systems.
The depletion of natural resources and the intermittence of renewable energy resources have pressed the need for a hybrid microgrid, combining the benefits of both AC and DC microgrids, minimizing the overall deficiency shortcomings and increasing the reliability of the system. The hybrid microgrid also supports the decentralized grid
A distributed optimal control strategy based on finite time consistency is proposed in this paper, to improve the optimal regulation ability of AC/DC hybrid microgrid groups. The control strategy is divided into two steps: one is within a microgrid and the other is among microgrid groups. In the element of control in a microgrid, the power
However, the microgrids installed in the last five years have tended to incorporate PV and battery storage with diesel generators as backup (i.e., PVDPS or solar hybrid microgrids), coping with around 63% of existing microgrids [4]. On the other hand, small scale

Hybrid ac/dc microgrid configurations are causing great interest as they combine the advantages of ac and dc architectures [52], [53], [22], [51], [55]. Their main characteristic is that the two networks—ac and dc—are combined in the same distribution grid, facilitating the direct integration of both ac- and dc-based DG, ESS and loads.
Solar hybrid microgrids have proven particularly valuable in remote areas and communities with limited access to reliable electricity. They have been deployed in off-grid regions, islands, rural communities, and developing countries, where they have empowered local populations, improved living conditions, and facilitated economic growth.
Hybrid AC/DC microgrids (MGs) provide efficient integration of renewable sources into grids and the interconnection of multiple MGs can improve system reliability, efficiency and economy by energy sharing.

Energy supply in remote areas (mainly in developing countries such as Colombia) has become a challenge. Hybrid microgrids are local and reliable sources of energy for these areas where access to the power grid is generally limited or unavailable. These systems generally include a diesel generator, solar modules, wind turbines, and
