  • Patent number: 10734810
    Abstract: A method for providing frequency load shedding in a power distribution network. The network includes a number of distributed switch-gear assemblies that control whether AC power is provided to groups of loads. The distributed switch-gear assemblies monitor the frequency of the AC signal to determine if a frequency event is occurring and also determine the direction of the power flow at the time of the event. The switch-gear assembly may open in an underfrequency event only if the loads are drawing power from the network, and the switch-gear assembly may open in an overfrequency event only if there is reverse power flow during the event. In addition, the order of operation of which switch-gear assemblies may open first in response to the frequency event is determined in advance by the location of the switch-gear assembly in the network and a corresponding time delay and coordinated frequency set-points.

  • Patent number: 10651652
    Abstract: Systems, methods, and computer media for managing frequency response in a power grid are provided herein. Individual grid-connected electrical devices can be turned on and/or off by corresponding frequency-responsive load controllers when frequency deviations beyond a threshold are detected. Each controller selects, for the corresponding electrical device, a frequency threshold from available frequencies in a frequency range. If the selected frequency falls within a deadband frequency range, then the controller sets the frequency threshold to a frequency outside of the deadband (e.g., to a closest available frequency outside of the deadband). On a system-wide level, this approximates a uniform distribution of frequency thresholds over the entire frequency range, including the deadband, and achieves the proper power-to-frequency relationship for grid stability.

  • Patent number: 10543376
    Abstract: Several defibrillators, defibrillator architectures, defibrillator components and methods of operating defibrillators are described. In one aspect, a defibrillator (as for example an automated external defibrillator) that can be powered by a mobile communication device such as a smart cellular phone or a tablet computer is described. Utilizing a phone (or other mobile communication device) as the power supply for an external defibrillator allows the external defibrillator to be smaller and, in some circumstance, removes the need for a battery that stores sufficient energy for shock delivery—which would need to be checked and/or replaced on a regular basis. Additionally, when desired, certain control functionality, computation, data processing, and user instructions can be handled/presented by the mobile communications device thereby further simplifying the defibrillator design and improving the user experience.

  • Patent number: 10530154
    Abstract: A control apparatus includes a receiving unit, a demand response unit, a power consumption fluctuation unit, a fluctuation-amount-estimation unit and an adjustment control execution unit. The receiving unit receives a demand pertaining to power consumption sent from an energy management apparatus. The demand response unit executes a demand-response control in order to adjust total power consumption of a plurality of devices set up in a property in accordance with the demand. The power consumption fluctuation unit executes a non-demand-response control in order to cause total power consumption to fluctuate regardless of the demand. The fluctuation-amount-estimation unit estimates a power consumption that will fluctuate due to the non-demand-response control during the demand-response control.

  • Patent number: 10523025
    Abstract: A voltage error signal is provided to a PWM controller of a voltage regular and used to produce a PWM signal that drives a power stage of the regulator. When operating in an adapter current limit regulation mode, an adapter current sense voltage, indicative of an adapter current, is compared to an adapter current reference voltage to produce an adapter current error signal. A compensator receives the adapter current error signal and outputs a compensated adapter current error signal. The adapter current sense voltage, or a high pass filtered version thereof, is subtracted from the compensated adapter current error signal to produce the voltage error signal provided to the PWM controller. Alternatively, an input voltage, or a high pass filtered version thereof, is added to the compensated adapter current error signal to produce the voltage error signal.

  • Patent number: 10523052
    Abstract: A wireless power transfer system includes a power receiver and a power transmitter providing power using an inductive power signal. The power transmitter includes a resonance circuit having capacitive and inductive impedances, and a driver configured to generate a drive signal for the resonance circuit. A frequency modification circuit is configured to control the resonance frequency of the resonance circuit by slowing a state change for the capacitive and/or inductive impedance for a fractional time interval of at least some cycles of the drive signal, The frequency modification circuit is configured to align at least one of a start time and an end time for the fractional time interval to transitions of a timing signal. In the power transmitter, the driver is configured to generate the timing signal to have transitions synchronized to the drive signal. The slowing may be by impeding current flow between the capacitive and inductive impedances.

  • Patent number: 10484945
    Abstract: Some aspects described herein reduce the negative performance impact associated with the voltage droop of a user equipment (UE) battery. For example, aspects described herein may be used to configure a UE with a pattern that includes a battery recovery time period that prevents a battery voltage of the UE from falling below a critical threshold and/or reduces the likelihood of the battery voltage falling below the critical threshold. In this way, UE performance may be improved, battery performance may be improved, battery life may be extended, and/or the like.

  • Patent number: 10396561
    Abstract: The present invention discloses a coordination control method of a multi-terminal VSC-HVDC transmission system. If a direct current voltage master control station shuts down, a direct current voltage control slave station takes over direct current voltage control, and remaining convertor stations keep original control modes. The takeover steps comprise that under the condition that inter-station communications are effective, the master control station sends a shutdown message to the slave station through the inter-station communications, and when the slave station monitors that the direct current voltage master control station shuts down, the slave station switches a current control mode into a direct current voltage control mode; and under the condition that inter-station communications fail or inter-station communications are absent, the slave station monitors changes of the direct current voltage of a system.
