With the ongoing trends in the energy sector such as vehicular electrification and renewable energy, the Smart Grid (SG) is clearly playing a more and more important role in the electric power system industry. One
This paper provides a comprehensive overview of the microgrid (MG) concept, including its definitions, challenges, advantages, components, structures, communication systems, and control methods, focusing on low
In total, to realize a smart grid, the integration of MGs into a power system is regarded as one of the essential technologies providing advantages such as enhanced stability, increased efficiency, higher RES integration, a continuous supply of loads in islanded mode, and so forth, compared to conventional distribution systems.
In , P. Ghalebani and M. Niasati presented a non-centralized droop-based control method with an LBcom system for achieving a more accurate power sharing and also a decreased voltage deviation in isolated DCMGs.

As mentioned, communication-based control methods can provide a global-/sub-optimal solution that cannot be achieved by communication-free control methods (decentralized methods). However, employing communication infrastructure in an MG can cause some serious challenges, such as a high establishment cost, low reliability, high complexity, etc.
To take advantage of MGs, their integration into the power grid should be performed based on proper and robust engineering to avoid possible adverse effects on the power grid, such as power quality, control, reliability, and problems .
In , an improved LBcom-based decentralized droop controller was developed for DC bus voltage restoration and accurate current sharing in DCMGs.
