The DOE defines a microgrid as a group of interconnected loads and distributed energy resources (DERs) within clearly defined electrical boundaries that acts as a single controllable entity with respect to the power grid.
The voltage and frequency stability during the system operation in the off-grid mode constitutes another difficult task to deal with. To mitigate the risk of microgrid instability, the electric energy balance needs to be ensured in the on-line environment.
