true microgrids are self-governed, and usually downstream of a single point of common coupling (PCC). Many of the most well known demonstrations are of this type. They are particularly easy to imagine because they fit neatly into our current technology and regulatory structure. Just as a traditional customer has considerable leeway in the operation of the power system on its side of the meter, so the restrictions on the nature of a µgrid are relatively loose. For this reason, one would expect much of the early deployment of microgrid technology to be of this type.
