Decision Support Systems and Methods for Complex Networks
This invention is a method of advanced contingency analysis visualization for power grid operations. It converts the large volume of contingency analysis results to a visual space and presents the results as user-friendly color-contoured maps. This novel visualization method unloads overwhelmed power grid operators from examining raw data and enables them to focus on critical portions of the grid and respond to adverse situations in a timely manner. The major point of novelty of this invention is the visual representation of the analysis results of multiple contingencies, which has not been done in the area of power grid operations. Geographical information is readily included in the visualization techniques. Another point of novelty is the quantitative assessment of risks. Comprehensive analysis of the contingency analysis results is performed and risk indices are derived. This quantitative risk assessment is not available in today’s tool. The developed visualization and analysis reveals the vulnerability of the power grid which otherwise would be buried in the pages and pages of tabular entries.
RADIATION MONITORING DEVICES AND ASSOCIATED METHODS (iEdison No. 0685901-21-0111)
The TRI-tag is an internally powered, miniaturized radiation sensing, electronic Bluetooth Low Energy (BLE) beacon tag. It includes an integrated novel, low-power, inexpensive solid-state gamma radiation detector. The device was designed for operation in rugged environments with no maintenance for up to 3 years. The tag mechanical package is completely sealed using a sonic welding method and requires no external connectors or penetrations to the case. In one use case, it may be mounted to the Cs137 and AmBe241 source shields used in the oil and gas service industry as part of the Well Logging Mobile Source Transit Security (MSTS) V2 system designed to improve situational awareness of radioactive sources as sources move from the home base of operation to a job site and back. The TRI-tag wirelessly sends indication of device tamper or removal, gamma radiation activity count, and a globally unique identification that may be associated with the asset it is mounted to in a back-end database at the time of installation. It has an additional feature that uses Near Field Communications (NFC) wake-up to support ultra-low power consumption during the time between its manufacture up until it is installed and placed into service. Power management has been optimized to provide long-life from the internal primary batteries prior to deployment and in normal operation. The NFC technology can wake the unit from deep sleep requiring almost no battery power prior to installation. Integration of this tag with the MSTS V2 system will provide improved capability to automatically detect when a shield is added/removed to a transport (truck or overpack) and when a source is removed or added to the shield that the tag is mounted to. Because the tag can be mounted directly to a shield without cables, the radiation activity level detected is less dependent on orientation or movement of the shield within the transport as opposed to a detector mounted to the wall of the source storage compartment. This makes the tag's usage much more convenient operationally.
Scheduling and modeling the operation of controllable and non-controllable electronic devices
Disclosed herein are representative embodiments of methods, apparatus, and systems for controlling and scheduling power distribution in a power network, such as household power network. One disclosed embodiment is a system comprising a central controller and a control device coupled to a household appliance. The central controller can comprise computing hardware coupled to a wireless transceiver. The central controller can be configured to generate and transmit control signals for controlling the operational state of the household appliance according to the schedule. Furthermore, the control device can be configured to receive the transmitted control signals from the central controller and to control the operational state of the household appliance in response to the control signals.

COORDINATION OF THERMOSTATICALLY CONTROLLED LOADS WITH UNKNOWN PARAMETERS
Apparatus and methods are disclosed for coordination of a population of Thermostatically Controlled Loads (TCLs) with unknown parameters to achieve group objectives including bidding and market clearing strategies designed to motivate self-interested users to realize efficient energy allocation subject to a peak power constraint. In one examples of the disclosed technology, a method of operating a load includes estimating a set of values for unmeasured parameters of the load's thermal environment based on output measurements of the thermal environment, determining an energy response based on the estimated set of values for the unmeasured parameters, and transmitting a bid for power for a finite time period based on the determined energy response to the coordinator. A clearing price is received from the coordinator responsive to the transmitted bid and power is sent to the load responsive to the received clearing price.
