A non-transitory computer readable medium includes instructions that, when executed by processing circuitry, are configured to cause the processing circuitry to operate in a recovery mode after initiating a startup operation, transmit a data frame to a device of an electric power delivery system during the recovery mode, the data frame indicating a request for a security association key (SAK), receive the SAK from the device in response to transmitting the data frame, and use the SAK to communicate data via a media access control security (MACsec) communication link.

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.

For example, a method can include receiving status information of a microgrid configured to connect to a grid, transmitting a live status update screen of the microgrid to a user, the live status update screen comprising a grid connectivity button configured to receive a user input and based on a received user input, transmitting a control signal to a microgrid interconnect device connected between the microgrid and the grid for coordinating one of connection or disconnection microgrid connected to the grid.

Systems and apparatuses include a circuit structured to: identify a first source object, a second source object, and a load bus object; determine locations of the first source object, the second source object, and the load bus object on a one-line topology; receive operational parameters of the first source object, the second source object, and the load bus object; define, using the one-line topology, a first route including objects electrically connected between the first source object and the load bus object; define, using the one-line topology, a second route including all objects electrically connected between the second source object and the load bus object; and control operation of the first route and the second route.

An aircraft seat having a voltage supply connection assigned only to the aircraft seat and/or at least one data connection assigned only to the aircraft seat, a voltage supply unit assigned to the aircraft seat and having a voltage input for connection to an on-board voltage network of an aircraft and at least one voltage output, each connected to another of the voltage supply connections. A switching arrangement is assigned only to the aircraft seat and connected between the voltage output and the voltage supply connection and/or between the data connection and a data network. A control unit is assigned only to the aircraft seat and connected to the switching arrangement. An infrared reading device is connected to the control unit and assigned only to the aircraft seat to wirelessly receive infrared signals from an external infrared transmitting device. The infrared reading device can receive infrared signals from a predetermined group of predetermined infrared signals, and the control unit can activate the voltage supply connections and/or at least one of the data connections by the switching arrangement, only in response to reception of a predetermined infrared signal.

An electric driven hydraulic fracking system is disclosed. A pump configuration includes the single VFD, the single shaft electric motor, and the single hydraulic pump mounted on the single pump trailer. A controller associated with the single VFD and is mounted on the single pump trailer. The controller monitors operation parameters associated with an operation of the electric driven hydraulic fracking system as each component of the electric driven hydraulic fracking system operates to determine whether the operation parameters deviate beyond a corresponding operation parameter threshold. Each of the operation parameters provides an indicator as to an operation status of a corresponding component of the electric driven hydraulic fracking system. The controller initiates corrected actions when each operation parameter deviates beyond the corresponding operation threshold. Initiating the corrected actions when each operation parameter deviates beyond the corresponding operation threshold maintains the operation of the electric driven hydraulic fracking system.

A device includes an input converter, an output converter, and a controller. The input converter is electrically coupled to an electrical meter and an energy production array. The output converter is electrically coupled to the energy production array and a load. The controller is communicatively coupled to the input converter, the output converter, the energy production array, and the load. The input converter and the output converter are positioned between the electrical meter and the load.

A system includes a processor operatively coupled to memory. The processor performs operations that include obtaining electrical measurements of a power system. The processor determines a scaled energy value of a first set of the electrical measurements that are scaled with respect to a second set of electrical measurements. The processor determines that a potential ringdown event occurred by comparing the scaled energy value to a threshold energy value. The processor determines that the potential ringdown event is a confirmed ringdown event by comparing a scaled error value to a threshold error value. The processor generates one or more mode estimates from the confirmed ringdown event.
