Abstract: Techniques are disclosed for providing a variable output micro-grid frequency in order to cause loads and producers coupled to a micro-grid to change operating modes/behaviors accordingly. For example, the utility frequency delivered via the micro-grid may be used as a control signal for the purposes of demand response, e.g., increasing or decreasing load, energy storage control, e.g., to cause storage of energy or the discharging of energy, and generator output curtailment as is mandated by generator interconnection standards such as UL1741 for output power curtailment under high frequency.

Abstract: Techniques for providing resilient energy distribution are provided. In an example, a microgrid can include a resilient circuit for supplying user equipment energy during a utility grid disruption and for supplying supplemental energy when the utility grid is not disrupted. The resiliency circuit can allow the microgrid to transition between utility disruption events and non-disruption intervals without disrupting energy to the user equipment.

Abstract: A plurality of end-user locations are served by a commercial utility grid. More than one and less than all of the end-user locations are themselves interconnected by a feeder, the feeder not metallically connected to the utility grid. The end-user locations each have a local AC bus that is not metallically connected to the utility grid or to the feeder, but that is linked by a coupler to both the utility grid and to the feeder. None of the local AC buses or the feeder is required to have the same phase or frequency as the utility grid. Locally generated electric power may be passed by means of the feeder to other end-user locations that are on the feeder. Each local AC bus has two or more inverters powering the bus.
