  • Load shedding in a guided surface wave power delivery system
    Patent number: 10536037
    Abstract: Disclosed are various embodiments of load shedding techniques for a guided surface wave power delivery system. In one embodiment, among others, a guided surface waveguide probe is configured to transmit a guided surface wave along a lossy conducting medium; and a load shedding controller device is configured to send load shedding instructions to a plurality of user devices. The load shedding instructions regulate user device consumption of electrical energy provided by the guided surface wave amongst the plurality of user devices by spreading out activation and deactivation of load shedding conservations amongst the plurality of user devices.

  • Load shedding in a guided surface wave power delivery system
    Patent number: 10027177
    Abstract: Disclosed are various embodiments of load shedding techniques for a guided surface wave power delivery system. In one embodiment, among others, a guided surface wave receive structure is configured to obtain electrical energy from a guided surface wave traveling along a lossy conducting medium. A user device is coupled to the guided surface wave receive structure as an electrical load, where a load shedding application of the user device is configured to receive load shedding instructions from a controller device coupled to the guided surface waveguide probe and is configured to regulate user device consumption of the electrical energy provided by the guided surface wave.
