  • Patent number: 8433452
    Abstract: A method for load control in an electrical distribution system using energy usage profiles based on temporal measurements. A load control unit (10) installed at a customer site profiles equipment (E1-En) directly connected to the load control unit and remotely located equipment (RE1-REn) wirelessly connected to the load control unit using measurements of time rather than energy usage. This reduces the cost and complexity of the load control unit. Profiling is done for individual pieces of load controlled equipment rather than for the site as a whole. This improves data resolution. The load control unit controls the load only when the equipment is powered, and adaptively synchronizes load shedding during this time, so to improve local load control performance. Termination of a load control event results in gradual reduction in load shedding so to control the inrush of demand seen by the distribution system.

  • Patent number: 8423197
    Abstract: A heater energization control apparatus. When an engine is stopped, a microcomputer of a GCU enters a power save mode. When the microcomputer returns to a normal mode in response to an interruption signal periodically generated from an interruption timer, the microcomputer supplies electricity to a heating resistor for a short time and obtains its resistance (S19). When the resistance is greater than a first reference value, the microcomputer determines that a glow plug is removed from the engine; that is, the glow plug is being exchanged (S29). The microcomputer sets an exchange flag to “1” (S30), and performs calibration for the heating resistor of a new glow plug after the engine is operated next time (S35). When the current resistance becomes smaller than the past resistance, the microcomputer determines that the glow plug has been exchanged.

  • Patent number: 8417391
    Abstract: The power flexibility of energy loads is maximized using a value function for each load and outputting optimal control parameters. Loads are aggregated into a virtual load by maximizing a global value function. The solution yields a dispatch function providing: a percentage of energy for each individual load, a time-varying power level for each load, and control parameters and values. An economic term represents the value of the power flexibility to different players. A user interface includes for each time interval upper and lower bounds representing respectively the maximum power that may be reduced to the virtual load and the maximum power that may be consumed. A trader modifies an energy level in a time interval relative to the reference curve for the virtual load. Automatically, energy compensation for other intervals and recalculation of upper and lower boundaries occurs. The energy schedule for the virtual load is distributed to the actual loads.

  • Patent number: 8352094
    Abstract: Embodiments of a system, a method, and a computer-program product (e.g., software) for aggregating an energy service from a group of loads with time-varying operating cycles are described. This aggregation may be performed by an aggregator, which provides the energy service to a power-system operator. In particular, for a desired demand response, a demand-response mechanism may modify a demand response of a given load by mapping an initial operating cycle of the load before a demand-response event to a final operating cycle. In addition, the demand-response mechanism may transition the given load to a new operating cycle associated with the demand-response event using a temporal set-point trajectory. This aggregation technique may ensure that a distribution of phases of the group of loads is, on average, uncorrelated with each other, either by preserving or modifying the distribution of phases prior to the demand-response event.

  • Publication number: 20120323391
    Abstract: A method and system is disclosed that includes a controller that determines a sleep schedule for reduced function devices on a home network. The devices have various sleep schedules in which to operate in an active state or a reduced function state. The controller determines the different schedules by sending communication messages to each device via a communication module. A timer is used to determine a sleep schedule for reduced function devices (RFDs) on the network. The sleep schedule is used to monitor when the devices are communicating on the network and are no longer able to communicate with the controller.

  • Patent number: 8328110
    Abstract: Electrical load spreading arrangements reduce peak power demand. An enclosure houses an electronic circuit board, which receives at a first input terminal a first thermostat control signal from a thermostat intended to control a first air conditioning unit and at a second input terminal a second thermostat control signal from a thermostat intended to control a second AC unit. A controller on the circuit board is programmed with instructions stored in a memory coupled to the controller causing the controller to monitor the first and second input terminals to determine the timing and duration of the thermostat control signals passed to the output terminals for activating or deactivating the AC units such that overlapping operation of the AC units is reduced particularly during peak demand periods. A similar arrangement may be applied to a broader class of HVAC equipment, including water heaters, for example.

  • Patent number: 8321058
    Abstract: A method of controlling an HVAC system including programming a thermostat of the HVAC system to define a temperature set point, a temperature differential around the temperature set point, and a number of cycles per hour for a temperature control source of the HVAC system. The method also includes sensing a temperature, executing a cycling control algorithm that includes the temperature, the temperature set point, and the number of cycles per hour as inputs to determine a duty cycle, and running the temperature control source according to the duty cycle when the temperature is within the temperature differential. The method further includes executing a deadband algorithm to turn on the temperature control source when the temperature is outside of the temperature differential at one extreme and to turn off the temperature control source when the temperature is outside the temperature differential at the opposite extreme.

  • Patent number: 8306634
    Abstract: An adaptive, user-centric system and network for controlling power consumption by an appliance is described. The appliance may be any type of powered apparatus, such as A/C units, heaters, computers, lights, kitchen appliances, home media centers, and so on. The power to these appliances is based on an estimated arrival time of the user to the destination where the appliance is located. It may also be based on previous performance data for the particular appliance, that is, given the current conditions (e.g., various environment temperature readings), how long has it taken in the past for the appliance to reach a certain level of operation. The location of the user is determined by a device that has some location-based services and is able to transmit this location/position data in a message to a power-control server. The server applies rules contained in the message to derive an estimated arrival time for the user which is used to power appliances at the user's destination.
