  • Patent number: 10332221
    Abstract: A utility is distributed to a group of subscribers via a distribution network. At least one parameter reflecting an instantaneous overall consumption of the utility in the distribution network is measured repeatedly, and an amount of the utility delivered to each subscriber in the group is controlled in response thereto. It is checked whether the instantaneous overall consumption of the utility is within an acceptable interval. If it is below a lower threshold level, at least one load is controlled to increase its consumption of the utility according to a pre-defined scheme in proportion to a deviation of the instantaneous overall consumption of the utility from the lower threshold level. If it is above an upper threshold level, at least one load is controlled to decrease its consumption of the utility according to the pre-defined scheme in proportion to a deviation of the overall consumption of the utility from the upper threshold level.

  • Patent number: 10116136
    Abstract: In a frequency control system, a system controller assigns load-specific threshold frequencies to electrical loads of a fleet of electrical loads. Load controllers perform load monitoring and control operations for controlled electrical loads of the fleet including (i) comparing a measurement of the electrical frequency with the threshold frequency assigned to the controlled electrical load and (ii) operating the controlled electrical load based on the comparison. For example, each load controller may perform operation (ii) by turning the controlled electrical load on if the measurement of the electrical frequency is greater than the threshold frequency assigned to the controlled electrical load, and turning the controlled electrical load off if the measurement of the electrical frequency is less than the threshold frequency assigned to the controlled electrical load. The threshold frequencies may be assigned based on State of Charge (SOC) values for the loads.

  • Patent number: 10114059
    Abstract: In the present invention, the connection between an external power supply and a unit for detecting welding of a relay is disestablished at least when a short circuit is detected, thereby preventing the short circuit from being falsely detected in the event that the short circuit and the welding of the relay can both be detected. A device for detecting welding of a relay detects welding of a relay provided to a path via which a cell is charged by an external power supply. Welding of a power-supply-side relay or a ground-side relay is detected on the basis of a current flowing disproportionately more toward the external power supply than the power-supply-side relay or ground-side relay when a control unit has deactivated the power-supply-side relay or ground-side relay during an interrupting in charging. A disconnecting switch establishes or disestablishes the connection between the external power supply and a weld-detection switch.

  • Patent number: 9478986
    Abstract: A load leveling system and a method for a power system are capable of attaining load leveling in a distribution substation unit. The load leveling system is for a power system with a controller having a major customer and lower transforming apparatus, and with a customer connected to the lower transforming apparatus via a low-voltage line. The system also has a communication unit between the customer and its own system, and control use time zones of devices within the customer, as well as an electric demand prediction unit, and a first load leveling processing unit. By employing such a system, it becomes possible to provide a load leveling system for a power system that is capable of realizing load leveling of both a distribution substation unit and a pole transformer unit.

  • Patent number: 9461472
    Abstract: A method and system for controlling electrical power in a micro-grid, especially during islanding when the micro-grid is disconnected from a main grid is described. A potential load shedding for islanding is determined when the micro grid is connected to the main grid. The potential load shedding is performed when a grid switch that connects the micro-grid to a main grid opens. A frequency based load shedding and a frequency based control of power injections to the micro grid may also be performed. The frequency based load shedding is performed with a faster response than the power injection control during islanding. The frequency based power injection control is performed with a faster response than the frequency based load shedding when the micro grid is connected to the main grid. A load shedding controller, an energy storage controller and methods performed by the load shedding controller, and the energy storage controller, respectively, is also provided.

  • Patent number: 9405303
    Abstract: Disclosed are exemplary embodiments of apparatus, systems and methods for power stealing for a wireless-enabled thermostat. In an exemplary embodiment, a wireless-enabled thermostat generally includes a control having a wireless network interface that intermittently connects the thermostat in a wireless network in accordance with a duty cycle, the duty cycle having a connect time in which the thermostat is connected in the wireless network and a sleep time in which the thermostat is not connected in the wireless network. A power stealing circuit of the thermostat steals power through an “on-mode” load of a climate control system to charge a capacitor or other energy storage device to provide the power for the wireless network interface. The control adjusts at least the sleep time in accordance with a time for charging the capacitor or other energy storage device to a threshold voltage.

  • Patent number: 9381923
    Abstract: An in-vehicle load control system configured to controllably drive one or more loads on a vehicle according to an input signal. The system includes a first electronic control portion configured to perform signal processing based on the input signal, and a second electronic control portion configured to controllably drive the load. A backup signal channel is provided independently of a signal channel through which a signal is transmitted in a multiplex communication portion to input the input signal to the second electronic control portion. The second electronic control portion receives a first control signal via the signal channel in the multiplex communication portion and a second control signal via the backup signal channel, and controllably drives the load by preferentially treating the first control signal when the ignition signal is on and by preferentially treating the second control signal when the ignition signal is off.

  • Patent number: 9263891
    Abstract: The present invention relates to a method and a system to reduce losses of energy due to ripples, especially at the power grid, the ripples being short term power shortages or excess power. The method is based on the idea of shutting off energy consuming devices during a period of power shortage, if their operation is not necessary, and optionally to turn on such energy consuming devices during periods of excess power, if energy may be stored in them, especially when energy may be stored as some physical parameter or variable, being a part of the operation of the energy consuming devices, such as the temperature of a freezer.

  • Patent number: 9071145
    Abstract: A power stealing circuit for stealing power to operate a control device is disclosed. In one illustrative embodiment, power may be periodically or intermittently diverted from a power source to a power stealing block. When power is diverted to the power stealing block, the power stealing block may steal power from the power source and store the stolen power on a storage device. The storage device may then provide operating power to a control device. In some embodiments, the power stealing block may include a first path for charging the storage device when a switch is ON, and a second path for charging the storage device when the switch is off.
