摘要:
A system of domestic appliances is provided, wherein the domestic appliances are operated from a branch of an, in particular public, supply system for electrical energy at a customary system frequency, wherein, in particular, the consumed energy which is supplied to the branch can be detected, and wherein a display and measurement unit is present, allowing the energy consumed by an individual domestic appliance to be displayed and measured. In this case, the functioning thereof for determining the consumption of the individual domestic appliance is based on the analysis of a characteristic structure, which can be assigned to the individual domestic appliance, of current and/or voltage profiles within system period time intervals during operation of the individual domestic appliance, wherein, for individual domestic appliances of which the inherent characteristic structure is small, the characteristic structure can be formed or added to by a structure generator.

According to an embodiment, management server includes estimator, scheduler, acquisition unit, monitoring unit, receiver and setting unit. Estimator calculates estimated value of energy demand in building with electric appliance. Scheduler creates schedule of appliance based on estimated value. Acquisition unit acquires actual value of energy demand. Monitoring unit monitors error between estimated value and actual value. Receiver receives DR signal containing information which prompts suppression of energy consumption in a designated period. Setting unit sets threshold. Estimator recalculates estimated value if error is equal or more than threshold. Scheduler reforms schedule based on the recalculated estimated value.

A system for managing delivery of electric power includes at least one source of electric power supplying an aggregate amount of available power and a plurality of electrical loads, each having a priority designation. There is a power management system electrically connected to the source of electrical power and to the plurality of electrical loads. The power management system monitors electrical power demanded by the electrical loads and the aggregate amount of available power of the at least one source of electric power. When the power management system determines that the aggregate demanded power exceeds the aggregate amount of available power, the power management system continues to provide power to each of said electrical loads but at a power level which is less than demanded to one or more of said plurality of electrical loads based on the priority designation of each of said electrical loads.

Embodiments of the present invention provide for a remotely controllable electrical socket. Such sockets may include an electrical conductor for receiving a plug of an electrical device. The plug may be associated with a tag for receiving identifying information that corresponds to the electrical device. Exemplary sockets may further include a tag reader for obtaining identifying information from the tag, a sensor for detecting if the plug is inserted in the outlet, and a communications interface for wirelessly sending information to a computing device regarding the identifying information and whether the plug is inserted in the outlet. The communications interface may also receive operational instructions from the computing device (e.g., to turn the power to the plug/electrical device ON or OFF).

A control device of an electrical apparatus configured to receive power from a facility that receives a supply of power from a system power supply, the facility including an energy management system that manages a power feeding schedule according to a first management function provided for managing the power feeding schedule for feeding power to the electrical apparatus, the control device includes an electronic control unit configured to: communicate with the energy management system; manage the power feeding schedule according to a second management function provided for managing the power feeding schedule in the control device; and determine whether the electronic control unit or the energy management system of the facility, will manage the power feeding schedule by comparing the first management function of the energy management system and the second management function of the control device.
摘要:
A battery management system/method implementing optimal dynamic battery charge/discharge cycling is disclosed. The system utilizes a power source control unit (PSCU) to selectively switch a power supply source to a battery charger that charges a battery servicing a portable computing device. The PSCU is controlled by a power monitor control unit (PMCU) that monitors the battery state and determines the optimal charge/discharge profile for the battery. Depending on the type and current condition of the battery as well as battery charge/discharge history, the PMCU monitors the historical, current, and/or anticipated demand activity of the battery to determine an optimal charge/discharge profile for the battery to enable maximum battery life under a wide variety of environmental and use profiles. Present invention methods control battery charge/discharge activity based on computing device historical/anticipated use characteristics, battery chemistry, and/or optimal battery lifecycle operation.
摘要:
An In Home Display (IHD) device adapted to display electricity usage of a household in data communication with a Smartmeter and in data communication with an intelligent power manager. The IHD provides a channel for the transmission of household descriptive data to the intelligent power manager. The intelligent power manager communicates with a number of IHDs each associated with a respective household. The intelligent power manager will process and compare data from the IHDs prompting a householder to take actions based on said comparison.
