1. An energy system, comprising:
- a microgrid comprising a network of at least one distributed energy resource and a plurality of loads, the at least one distributed energy resource being configured to supply power to the plurality of loads, the microgrid being configurable to connect to one of a plurality of feeder circuits of a main power grid at one of a plurality of coupling interface locations, respectively;
wherein the microgrid, responsive to an event, is further configured to disconnect from a first one of the plurality of feeder circuits at a first one of the plurality of coupling interface locations of the main power grid, to determine a power distribution between power supplied by the at least one distributed energy resource and power supplied via a second one of the plurality of feeder circuits of the main power grid, and to connect to a second one of the plurality of feeder circuits at a second one of the plurality of coupling interface locations.

Abstract
An energy system includes a microgrid including a network of at least one distributed energy resource and a plurality of loads, the at least one distributed energy resource being configured to supply power to the plurality of loads. The microgrid is configurable to connect to one of a plurality of feeder circuits of a main power grid at one of a plurality of coupling interface locations, respectively. The microgrid is also configurable to expand or shrink its power supply area according to the available power generation capabilities.
