The state of the art on microgrid operation typically considers a flat and static partition of the power system into microgrids that are coordinated via either centralized or distributed control

The centralized control layer is the microgrid control center (MGCC) and the core of the microgrid control system. It centrally manages DGs, ESs, and loads, and monitors and controls the entire microgrid.
Encompasses load and generation and acts as a single controllable entity with respect to the grid. Can disconnect and parallel with the local utility. Intentionally “islands” as part of a planned
Microgrid control systems: typically, microgrids are managed through a central controller that coordinates distributed energy resources, balances electrical loads, and is responsible for
The control algorithms inside the microgrid controller are what enables the microgrid operation objectives to be achieved. Popular control techniques include rule-based (RB) and optimal dispatch
In case of emergencies such as blackouts, tertiary control can manage a group of interconnected microgrids to form what is called "microgrid clustering", acting as
The secondary control, as a centralized controller, restores the microgrid voltage and frequency and compensate for the deviations caused by the primary control.
Microgrid control relies on several specialized modes, each designed to address
The two control approaches for microgrids namely hierarchical control and distributed control are presented in Reference 207, where, the main features of
Majorly, MGs are controlled based on the hierarchical control strategy, including three control layers named primary, secondary, and tertiary
