Though there are many specific definitions of a microgrid, at its core a microgrid means the ability of a distributed energy resource, typically solar PV and battery energy storage, to both interact with the utility grid and stand alone with no utility. From a technical perspective, what are the key elements to achieve this functionality?
- Managing the point of interconnection (POI)
- Power equipment mode shifting
Managing the point of interconnection
The point of interconnection is the specific point where the facility’s power network touches or interacts with the utility company’s centralized grid. This is typically within or ahead of the main utility service equipment, though it could also be to isolate a sub panel of priority loads from the overall facility load. Managing the POI involves monitoring and actioning a complete disconnection of the facility from the grid.
