Abstract: Composite antennas and methods of forming the composite antennas are described. In one example, a composite antenna includes a plurality of strips of carbon fiber material, and a metal shim strip. A portion of the metal shim strip is positioned and embedded between two of the strips of carbon fiber material in a layup stack of the strips of carbon fiber material and the metal shim strip. In another example, a method of forming a composite antenna includes cutting carbon fiber material into a plurality of strips of carbon fiber material, cutting metal shim stock into a metal shim strip, arranging the strips of carbon fiber material, the metal shim strip, and an uncured resin into a layup stack of material, and curing the layup stack of material to form a laminate stack.

Abstract: A method for implementing power delivery of an integrated renewable energy source and energy storage system (RES?ESS) facility includes a renewable energy source (RES) and an energy storage system (ESS). The method comprises obtaining a first control rule configured to be used to control power distribution in the RES?ESS facility for a time slot, wherein the power distribution includes directing power from a renewable energy source (RES) to an electric grid and to an energy storage system (ESS) and power from the ESS to the electric grid; receiving a second control rule configured to be used to control the power distribution in the RES?ESS facility, wherein the second control rule was used to control the power distribution in the RES?ESS facility for the time slot; determining a difference in performance of the RES?ESS facility; and transmitting a record comprising an identification of the difference in performance.

Abstract: An integrated renewable energy source (RES) and energy storage system (ESS) facility configured to supply power to an AC electrical grid includes energy storage system capacity and inverter capacity that are larger than a point of grid interconnect (POGI) limit for the facility, enabling high capacity factors and production profiles that match a desired load. At least one first DC-AC power inverter is associated with RES, and at least one second AC-DC power inverter is associated with the ESS. AC-DC conversion is used when charging the ESS with RES AC electric power, and DC-AC conversion utility is used when discharging ESS AC electric power to the electric grid. Aggregate DC-AC inverter utility exceeds the facility POGI limit, and excess RES AC electric power may be diverted to the second inverter(s).

Abstract: Methods for implementing power delivery transactions between a buyer and a seller of electrical energy supplied to an electrical grid by an integrated renewable energy source (RES) and energy storage system (ESS) of a RES-ESS facility are provided. Estimated total potential output of the RES is compared to a point of grid interconnect (POGI) limit to identify potential RES overgeneration, and the buyer is charged if potential RES overgeneration is less than potential overgeneration during one or more retrospective time windows. The method provides a basis for the RES-ESS facility owner to be paid for an estimated amount of energy that did not get stored as a result of a grid operator not fully discharging an ESS prior to the start of a new day.
