Well, okay, some microgrids are electrical islands, particularly those that are on a literal island or in a desert or on a mountaintop or somewhere no central grid exists. They function in a stand-alone fashion, or in industry parlance islanded.. Others operate independently just some of the time, separating from the central grid during a

With the development of island microgrids (IMGs), several adjacent IMGs can be formed as multi-IMGs to improve their operation economy and power supply reliability through energy sharing [[1], [2], [3]]. However, due to the harsh marine environment, there are not constantly engineering conditions for laying submarine cables
