Abstract:
Provided is a method of controlling a network system. In the method, it is determined whether a communication modem of an electric product is operable by transmitting a signal between the communication modem and a component. If the communication modem is operable for communication with the component, an operation of the electric product is controlled based on power information received through the communication modem.
Abstract:
An example energy management unit (EMU) with diagnostic capabilities is provided. The EMU with can receive and identify the operational status of a device by receiving an audio signal from the device generated by the device's self diagnostic system. The EMU can decode the diagnostic information and retransmit the decoded information as necessary for further processing.
Abstract:
The subject specification comprises enhanced communication infrastructure for a multi-tier hierarchical smart distribution grid (SDG). The SDG comprises a specified number of distribution network node controller (DNNC) components employed to desirably control communications and power distribution between respective tiers of the SDG to facilitate efficient power distribution. When communication between the a DNNC in one tier and another DNNC in another tier, is desired, the DNNC can identify available communication channels and respective communication conditions of the available communication channels, and can dynamically select a subset of available data and preferred communication channel, based at least in part on predefined control criteria, to control data transmission loads in the network and facilitate real time control of the SDG. Data can be communicated via the selected communication channel. Respective DNNCs can desirably control power distribution for respective tiers, minimizing upper tier involvement in lower tier power distribution.
Abstract:
A method for reducing effects of a demand/response event in a power distribution network can include identifying a load profile in the power distribution network, in response to detecting a peak in the load profile, decreasing voltage in the power distribution network and in response to a detecting a trough in the load profile, increasing the voltage in the power distribution network.
Abstract:
A system for analyzing energy usage measures one or more parameters indicative of energy usage for a plurality of sub-circuits, where the sampling rate for the measuring is substantially continuous, and automatically transmits information related to at least one of the measured parameters at a rate that enables monitoring of current energy usage. The system further detects a significant change in a measured parameter, determines whether the significant change in the measured parameter is caused by a change in energy usage, and automatically transmits information related to the significant change in the measured parameter caused by the change in energy usage after detecting the significant change.
Abstract:
A power distribution system includes: a remote electricity monitoring device which is provided at each power supply destination, and remotely reads, via communication means, an consumed power amount and an surplus power amount stored in a power storage device at each supply destination; and a management server which manages the power supply of each supply destination while collecting, via the communication means, the consumed power information and the surplus power information, both of which are read by the remote electricity monitoring device. The management server distributes the power among the supply destinations in line with the relationship between the power amounts based on the consumed power information and surplus power information.
Abstract:
An approach for management and monitoring of auto demand response in a multi-site enterprise. It may provide awareness of upcoming demand response events, monitoring actual responses to demand response events, analysis of energy management and command system performance, an ability to opt-out of a demand response event, and management and control of the demand response strategy. At the enterprise level, an auto demand response supervisor may add management and monitoring functionality. Added capabilities may incorporate message exchanging with the site-level auto demand response service, support for user interfaces that allow event monitoring and enable management actions such as opting-out of an event. At the site level, functionality may be an extension to the auto demand response service. Added capabilities may incorporate message exchanging with the enterprise-level auto demand response supervisor service, and an event response mechanism and user interface that enable a management decision to opt-out an event.
Abstract:
Electrical vehicle profiles for power grid operation. Embodiments of the invention can provide systems and methods for collecting and storing electrical vehicle usage and charging information, which may enable the generation of usage and charging profiles. Additionally, these usage and charging profiles may be usable to operate electricity grids in areas where electrical vehicles are prevalent. Grid maintenance, as well as power allocation, may be controlled based at least in part on the usage and charging profiles.
Abstract:
A method and apparatus is disclosed for providing protection against arc flash during maintenance on a low voltage power circuit including a circuit breaker having a specified trip function for responding to a fault is provided. The specified trip function is overridden with a maintenance trip function that results in reduced arc energy in the fault during a trip over arc energy during a trip with the specified trip function. The specified trip function is restored following maintenance.
Abstract:
An appliance network connectivity apparatus includes a voltage sensor that generates a signal at an output that is proportional to a voltage provided to the appliance. A current sensor generates a signal at an output that is proportional to a current flowing through the appliance. A processor determines the electrical characteristics of power consumed by the appliance and executes web server software for communicating data through a network. A relay controls power from the power source to the appliance. A memory stores the electrical characteristics. A network interface provides the electrical characteristics to the network.
