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.12-22-2011
20110313587Integrated Wireless Power Control Device - An integrated power control device and method are provided. In one embodiment, a device includes a body, a plurality of sockets for connection with a load, and a plurality of switch-controls each connected with corresponding one of the sockets and controlling power connecting to the load. The device further includes a microprocessor for the input, output, calculation and control of data and information flow, wherein the microprocessor issues commands to the switch-controls to execute switch on or off on the sockets, a timer, and a data storage unit for data storage so as to provide the microprocessor to access the data. A voltage-and-current detector detects voltage and current values and stores them into the data storage through the microprocessor. A voltage-current alerting unit receives the voltage values and current values and informs the microprocessor when the values exceed predetermined thresholds. Finally, a power computational unit calculates power consumption of the load.12-22-2011

The system comprises a cold control device including a housing and a counter spring having at least one spring tension position corresponding to a temperature set point, a bourdon tube having a first end comprising an elastomeric diaphragm operatively associated with the counter spring, and a second end, opposite the first end, located in the compartment, wherein the counter spring is capable of providing a force against the diaphragm, and a DSM switching device operatively controlled by an associated DSM module. The DSM module is configured to receive a signal indicative of at least one of a peak or non-peak demand period of an associated utility.02-02-2012
20120046797PEAK LOAD OPTIMIZATION USING COMMUNICATING HVAC SYSTEMS - An HVAC system includes a first and a second electric motor. A load manager is coupled to the first electric motor. The load manager is configured to prevent the first electric motor from operating simultaneously with said second electric motor.02-23-2012
20120059530ENERGY MANAGEMENT DEVICE AND METHOD - An energy management device manages a plurality of monitored devices distributed in a plurality of monitored areas. The energy management device determines whether a current time of each monitored area is during a monitored time of the energy management device. The energy management device acquires an area identifier and a body presence information from each of the monitored areas, and determines whether one or more monitored areas are under control and without body presence. If one or more monitored areas are under control and without body presence, the energy management device transmits one or more power-off commands to turn off the monitored devices located in the one or more monitored areas.03-08-2012
20120095609ENERGY RESPONSE MANAGEMENT - TIME OF DAY METHOD - An energy management system is provided for an appliance comprising: an interface to receive a schedule having an off-peak time segment and an on-peak time segment; a control to determine an operation to be performed by the appliance; a mode selecting device to select between an energy management mode and an immediate start mode; and a controller connected to the interface, the control, and the mode selecting device; the controller includes a memory for storing the schedule and firmware to determine whether there is any off-peak time segments and overnight time periods between a current time and a deadline for completing the operation; wherein upon selection of the energy management mode, the controller is arranged to initiate the operation when an amount of time required to complete the operation maximizes the off-peak time segment between the current time and the deadline; and upon selection of the immediate start mode, the controller is arranged to initiate the operation immediately; and, deactivating an element of the operation if the operation is during the overnight time period.04-19-2012
