Due to inadequate power output or excessive renewable-based generation, a freestanding microgrid (MG) may regularly encounter overloading, which can result in undesirable voltage and frequency aberrations. Additionally, they reduce the load on the utility grid. However, given that they depend on unplanned environmental factors, these systems have an unstable generation. . Microgrids (MGs) have the potential to be self-sucient, deregulated, and ecologically sustainable with the right management.

Central power system failures have persisted as a result of the microgrids' instability. Microgrid technology integration at the load level has been the main focus of recent research in the field of microgrids. The conventional power grids are now obsolete since it is difficult to protect and operate numerous interconnected distributed generators.
The outcomes of case studies demonstrate that there are several ways to deploy microgrid management systems, depending on the system's size, grid connectivity, technology, automation, and capital cost. In order to address new issues for the creation of AI applications in the future, follow-up research fields are also identified .
