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.
