  • Patent number: 11916388
    Abstract: An electrical power distribution control system configured to issue a demand response signal to cut power to a plurality of electrical power consuming loads within an electrical power distribution network to reduce a peak power demand within an electrical power grid during a peak power demand. Unlike conventional demand response systems, the controller in each consumer residence includes both a distributed control based on the ability to track individual 24 hour usage patterns and selectively delay the demand response signal on individual resistive heating loads based on usage patterns for the purpose of reducing a likelihood of consumers experiencing effects of the reduced peak power demand.

  • Publication number: 20210071925
    Abstract: A load control device for improving energy efficiency of a heating, ventilating, and air-conditioning (HVAC) system by controlling shed times of a compressor of the HVAC system. The load control device includes a compressor cutoff switch, a sensing circuit, and a processor. The processor determines a subsequent mandatory shed time based upon a previous shed time, a previous run time, and a minimum run time. A subsequent mandatory shed longer than the previous mandatory shed time causes a subsequent run time to be increased, thereby increasing system efficiency.

  • Patent number: 9927131
    Abstract: Systems and methods for storing power from distributed generation systems or other loads and sources that affect line voltage are disclosed. In embodiments, a water heater can be powered in a way that absorbs excess power from the grid by heating water when a controller senses excess power generation in the grid. Excess power generation can be sensed by either an increase in line voltage amplitude above a predetermined standard, or an increase in line voltage frequency above a predetermined standard.

  • Patent number: 9528717
    Abstract: An extended run time device for extending the time that a compressor-based heating, ventilating, and air-conditioning (HVAC) system runs so as to increase energy efficiency of the HVAC system. The extended run time device includes a sensing circuit, a switching device and a processor. Based upon a signal from the sensing circuit, the processor causes the switching device to transmit a proxy control signal to the compressor, thereby causing power to the compressor to be maintained for a time period longer than a time period requested by the temperature control device.
