Microgrid For Saving Critical Loads

In power system, the existence of distributed energy resources (DERs) is increasing, which in turn led to the attention of microgrid (MG). As the MG is the promising future of the smart grid (SG), it can be used when the main grid is unavailable in order to feed critical loads or in countryside areas, particularly in faraway unreachable areas. In this paper, we design a MG model using Matlab/Simulink to restore service to critical loads when the main grid feeding is cutting off under any circumstance. The simulation results showed how the control in MG operation modes can save critical loads.
