This paper gives an outline of a microgrid, its general architecture and also gives an overview of the three-level hierarchical control system of a microgrid. A microgrid is a group of interconnected loads and distributed energy resources. The hierarchical structure is the most accepted method for microgrid control tha has three levels including primary, secondary, and tertiary.

This calculator sizes core components using planning equations commonly used in early-stage microgrid design. It treats energy targets (kWh/day) separately from power targets (kW) to avoid undersizing inverters and storage. If daily energy is entered, it is used directly.

They are often used to provide power to remote communities or to integrate renewable. In the context of a microgrid, wind turbines can provide ancillary services that are useful in both islanded and grid-connected modes, as demonstrated in previous parts of this report series.
