Abstract:
1. A microgrid comprising: (a) a utility interconnect connecting the microgrid to an electric utility power distribution system; (b) an underground power distribution system wherein the underground power distribution system is configured to have a feature selected from redundant power distribution capabilities and being wired as a loop distribution system with sectionalizing switches; (c) a microgrid controller; (d) a first set of loads comprising all nonresiliant mission critical loads in the microgrid; (e) a second set of loads comprising all resilient mission critical loads in the microgrid not contained in the first set of loads; (f) a combined mission critical load comprising the first set of loads and the second set of loads; (g) a first power generation source; (h) a second power generation source wherein the second power generation source is a renewable energy power generation source; (i) a quantity of fuel supplies sufficient to sustain the combined mission critical load for at least six months without connection to the electric utility power distribution system; (j) an energy storage device; (k) a third set of loads; (l) a fourth set of loads; (m) wherein a total on-site power generation comprising the first power generation source and the second power generation source is sufficient to supply both the combined mission critical load and the third set of loads; (n) wherein the total on-site power generation capability meets N+1 criteria for the combined mission critical load; (o) wherein the utility interconnect comprises a first advanced metering infrastructure; (p) wherein the first set of loads is connected to the underground power distribution system; (q) wherein the first set of loads comprises a second advanced metering infrastructure; (r) wherein the first set of loads comprises an uninterruptible power supply; (s) wherein the second set of loads is connected to the underground power distribution system; (t) wherein the second set of loads comprises a third advanced metering infrastructure; (u) wherein the first power generation source comprises a fourth advanced metering infrastructure; (v) wherein the second power generation source comprises a fifth advanced metering infrastructure; (w) wherein the third set of loads comprises a sixth advanced metering infrastructure; (x) wherein the fourth set of loads comprises a seventh advanced metering infrastructure; and (y) wherein the advanced metering infrastructures are comprised of a collection of elements having some form of electromagnetic pulse protection including a smart metering devices and an automated switching device that are configured for secure two-way communications with the controller.
