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.

Disconnect load control receiver for resistive heating loads

A controller and method are usable to control the provision of electrical power from a local electrical network to a power grid. If it is determined that changes in the power grid voltage are correlated with the provision of power to the power grid, the power that is being provided to the power grid is manipulated so that the rate of change of the wattage that is provided to the power grid does not exceed a predetermined ramp rate. Such a manipulation is accomplished by adjusting an operational parameter of one or more electrical loads that are connected with the local electrical network.

Controller and method of controlling power supplied from a small power source to a power grid

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.

Electric water heater systems for power grids with distributed generation

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.

Efficiency heating, ventilating, and air-conditioning through extended run-time control

A load control receiver (LCS) for controlling an electrical load. The LCS includes a power sensing arrangement that monitors power usage of the load; a processor that predicts future power usage based on prior power usage; a transceiver that receives load shedding commands; and a controllable switch that can interrupt power supplied to the attached loads, based on load shedding commands.

Distributed electricity demand-reserve prediction

A method, device, and system for controlling power delivered to a power-consuming device. The device can receive a control signal from a thermostat, where the control signal activates the device. The device can then determine when a control event is to occur. At such time, the device terminates power delivered to the power-consuming device and continues to withhold the power until the control event expires. When the control event has ended, the device allows power to flow to the power-consuming device. The device uses a timer and a communication component to send and receives signals associated with a control event to a user.

Low voltage load control switch

An adaptive-fan-control (AFC) communicating thermostat for controlling an electrical load and controlling an HVAC circulation fan during a load control event. The thermostat interrupts and overrides an occupant-selected fan setting of the thermostat. The AFC communicating thermostat includes a controller in communication with a temperature sensor and the occupant-selectable fan control.

Utility-driven energy-load management with adaptive fan control during load-control events

A method for managing a utility load by controlling electrical consumption of electrically powered devices. The method includes selecting a target for load control forming a single variable length load control message according to a communication protocol. The load control message includes the target address and a plurality of unique concatenated command messages, each of the plurality of unique concatenated command messages being selected from the set consisting of a command message having a predetermined message type and a fixed length message defined for the predetermined message type and a command message having a predetermined message type and a variable length message corresponding to values in a command message control flag field defined for the predetermined message type. The method also includes causing the single variable length load control message to be transmitted to the target and receiving a reply message formed according to the communication protocol from the target.

Utility load control management communications protocol

A load control management protocol, system, and method that address many different customers, individually, in geographic groups, or in other predefined groups to control at least one or more electrical power consuming appliances are disclosed. The computer-implemented protocol provides wired and wireless communication schemes that enable a utility to quickly and efficiently communicate commands and messages to end user devices. Specific electrically powered appliances and certain uses of electricity can therefore be managed by communicating with the controllers of those appliances, providing management of a utility load during peak price and consumption periods to prevent delivery interruptions.

Control of a variable output appliance of a small energy consumer participating in an electrical load shedding program. A baseline operating characteristic of the appliance is determined for ordinary operation (such as in an absence of any load shedding requirements). An amount by which to reduce output of the appliance is determined in accordance with the load shedding program. Operation of the appliance is controlled to achieve the output reduction in accordance with the load shedding. This approach enables providing incentive for the small energy consumer to participate in the load shedding program, the incentive being based on the amount by which output is reduced, thereby representing a reduction of actual energy consumption for that small energy consumer.
