An energy saving support system according to an embodiment is configured to provide a consumer, who has an electric load to which electric energy is supplied from an electric power supply system within a house, with energy consumption-related information through a photo frame or the like. The information providing apparatus is configured to acquire an acceptability level, which stepwise indicates a degree of interest of the consumer in the energy consumption-related information, and to determine the energy consumption-related information to be newly provided to the consumer based on the acceptability level.

A system provides a “virtual room” for remotely sharing content experiences via electronic devices at different locations. The system may enable synchronization of the content at the different locations, access control, be able to provide and/or experience interaction feedback regarding the content, control the interaction feedback that is provided and/or experienced, enhance the ability of people to distinguish the content from the interaction feedback, and so on. As such, people may be able to share content experiences more like they were present in a single location while remote from each other.

Systems and methods to disconnect a faulted region of a power grid are described. For example, a control system may obtain a set of regions of a power grid. The control system may obtain a current magnitude and a voltage magnitude of the power grid. The control system may detect a fault in the power grid based at least in part on the current magnitude. The control system may, from the set of regions, determine a faulted region that the fault is located within based on a voltage magnitude of one or more buses in the power grid, a net change in power with respect to time of one or more regions in the set of regions, or both. The control system may send one or more signals to electrically disconnect the faulted region from the power grid.

A control system (300) allows recognized standard premise electrical outlets, for example NEMA, CEE and BS, among others to be remotely monitored and/or controlled, for example, to intelligently execute blackouts or brownouts or to otherwise remotely control electrical devices. The system (300) includes a number of smart receptacles (302) that communicate with a local controller (304), e.g., via power lines using the TCP/IP protocol. The local controller (304), in turn, communicates with a remote controller (308) via the internet.

A server performs a process including: when the server receives a second DR execution instruction, the step of obtaining a vehicle list; the step of turning off a determination flag of each candidate vehicle; the step of obtaining a number of times of turning on and off a relay at a time of DR for one of candidate vehicles each showing a determination flag in an OFF state; when the number of times of turning on and off the relay is greater than a threshold value, the step of turning on an exclusion flag; the step of performing a notification process; when a determining process ends, the step of performing a process of allocating a DR amount; and the step of transmitting a DR signal.

The present disclosure provides an electrical system that includes an energy control system, a photovoltaic (PV) power generation system electrically coupled to the energy control system, an energy storage system electrically coupled to the energy control system, and a smart load panel electrically coupled to the energy control system and to a plurality of backup loads. The energy control system operates in an on-grid mode electrically connecting the PV power generation system to a utility grid and a backup mode electrically disconnecting the PV power generation system from the utility grid. The smart load panel selectively disconnects one or more of the plurality of backup loads from the energy control system when the energy control system is in the on-grid mode and when the energy control system is in the backup mode.

An electrical panel or an electrical meter may provide improved functionality by interacting with a smart plug. A smart plug may provide a smart-plug power monitoring signal that includes information about power consumption of devices connected to the smart plug. The smart-plug power monitoring signal may be used in conjunction with power monitoring signals from the electrical mains of the building for providing information about the operation of devices in the building. For example, the power monitoring signals may be used to (i) determine the main of the house that provides power to the smart plug, (ii) identify devices receiving power from the smart plug, (iii) improve the accuracy of identifying device state changes, and (iv) train mathematical models for identifying devices and device state changes.

A method recognizes topology in low-voltage networks including local substations each having a plurality of output lines connected to a controllable electrical resource, and a control apparatus of each local substation. The method uses a computer arrangement assigning resources to the control apparatuses based on geographical proximity, selecting an assigned resource, transmitting a test control command specific to the selected resource from the control apparatus to the assigned resources, the test control command configured to trigger a change in power consumption or power output of the selected resource, measuring a change in an electrical variable on the output lines of the local substation by using a measuring apparatus, and assigning the selected electrical resource to that output line of that local substation on which a correlation between test control command and change is recognized. An arrangement for recognizing a topology in a low-voltage network is also provided.
