Solar photovoltaic microgrids are reliable and efficient systems without the need for energy storage. However, during power outages, the generated solar power cannot be used by consumers, which is one of the major limitations of conventional solar microgrids. This results in power disruption, developing hotspots in PV modules, and significant loss of

Solar MGs have the potential to be an environment-friendly energy option. However, the output of solar photovoltaics (PV) is constrained by its fluctuating nature. Therefore, a suitable control technique is imperative. Solar MGs are commonly used to power schools, street lights, homes, businesses, hospitals and irrigation pumps for agriculture.

The planning and operation of microgrids hold substantial implications for the future of electric power systems. MGs mirror traditional power systems regarding distributed generation resources, storage systems, load management, and interconnection lines.
Different approaches to address PV variability Solar variability affects the irradiance measured by sensors as well as the power produced by one or several PV panels. Two time-scales are important for microgrid operation and planning:
The reviewed studies present a diverse array of optimization strategies for microgrid performance enhancement, focusing primarily on energy management, cost reduction, and system reliability.

The term “microgrid” refers to the concept of a small number of DERs connected to a single power subsystem. DERs include both renewable and /or conventional resources . The electric grid is no longer a one-way system from the 20th-century . A constellation of distributed energy technologies is paving the way for MGs , , .
Due to the relatively small size of microgrids compared to utility grids, their sensitivity to power fluctuations is significantly increased, with the result that developers now have to account for power dynamics, flexibility and production uncertainties [ 25, 26 ].
