The device, method, and system embodiments described in this disclosure (i.e., the teachings of this disclosure) enable an authorization circuit having at least one authorization mechanism to cooperate with an access circuit having at least one key mechanism. Upon successfully authorizing at least one datum communicated from the key mechanism of the access circuit, the authorization circuit is arranged to deliver power having determined characteristics to the access circuit. In at least one embodiment, the authorization circuit is arranged as a circuit wired or wirelessly coupled to a power infrastructure in a building. In at least one embodiment, the access circuit is arranged as a smart power plug arranged to temporarily deliver power to a mobile computing device or other electrically powered device. In some cases, power is only delivered after a user consumes certain multimedia information. In some cases, power that is delivered is delivered for only a short time and is measured.

An apparatus for a system power device utilized in an interconnected power system. The interconnected power system may include multiple system power devices connected to various inter connections of groups of direct currents (DC) from power sources which also may be connected in various series, parallel, series parallel and parallel series combinations for example. The apparatus may include a processor connected to a memory and a communication interface operatively attached to the processor. The communication interface may be adapted to connect to a mobile computing system of a user in close proximity to the system power devices. A graphical user interface (GUI) of the mobile computing system may allow various operational and re-configuration options for the interconnected power system which may include installation, maintenance and monitoring schedules in the interconnected power system when the user of the GUI is in close proximity to the system power devices.

A method includes providing a net consumption trajectory comprising net consumption targets for one or more subperiods of a time period. Each net consumption target indicates a target difference from a beginning of a time period to an end of the subperiod between total consumption and total production or offset. The method also includes generating, for a subperiod of the plurality of subperiods, a set of curtailment actions predicted to achieve the net consumption target for the subperiod and implementing the set of curtailment actions.

Systems, methods, and computer-readable media are disclosed. An example method may include receiving a single-line drawing (SLD) of a power substation, the SLD including one or more components, the one or more components including at least one of: a current transformer (CT), a circuit breaker (CB), an isolator, a feeder, and a busbar. The example method may also include analyzing, using an artificial intelligence (AI) system, connection paths associated with the one or more components in the SLD. The example method may also include receiving real-time data relating to a status of the CB and a status of the isolator. The example method may also include providing, based on analyzing the connection paths, and the real-time data relating to the status of the CB and the status of the isolator, an indication of topology information associated with the power substation, the topology information including at least one of: an indication that the CT is a checkzone CT, an indication that the CT is a deadzone CT, an indication of a zone associated with the CT or the CB, or an indication that a zone is unprotectable.

A method, system and computer-readable medium of directed towards improving battery storage is provided. In some embodiments, battery storage formulations are provided and an impact of the constraints on the computational performance of security constrained unit commitment (SCUC) is determined. For example, binary variables may be generally required due to mutual exclusiveness of charging and discharging modes. In some embodiments, valid inequalities may be used to improve state of charge (SOC) constraints. Adding batteries to the Regional Transmission Organizations (RTOs)/Independent System Operators (ISOs) day ahead market clearing cases may reveal an impact of binary variables and the valid inequalities on SCUC solving time. Warm start and lazy constraint techniques may be applied to improve the performance and make the valid inequalities more effective, reducing computation time to acceptable levels for implementation.

Systems and methods for determining a location of an event in an electric power delivery system using a machine learning engine are provided. The machine learning engine may be trained based on a topology of the electric power delivery system, where the topology may be a layout of line sections and corresponding sensors of the electric power delivery system. Based on the topology, one or more training matrices that indicate possible event locations may be generated. In turn, the machine learning engine may be trained using the training matrices and logistic regression models to determine locations of events that occur during operation of the electric power delivery system.

An appliance management method is designed to make power distribution equipment, provided on a power supply channel, control and/or monitor an appliance to be electrically connected to the power distribution equipment. The appliance management method includes an authentication step and a management step. The authentication step includes allowing a high-order system to perform authentication on the power distribution equipment by making the power distribution equipment access the high-order system via a public network after the power distribution equipment has been energized. The management step includes making the power distribution equipment that has been authenticated in the authentication step control and/or monitor the appliance.

A tethered aircraft or balloon carrying a communications base station for rapid deployment in emergency situations. Electrical power is delivered from a generator on the ground using a pulsed electrical supply system in which each power pulse is delivered over a cable and acknowledged, and pulses only continue to be delivered whilst such acknowledgements are received by the ground station. This reduces the risks associated with delivering electrical power over an aerial tether, and avoids the need for an earth (ground) connection, reducing the risk from lightning.

A method for flexible coordinated operation of an urban distribution network and a watershed network, including: constructing a watershed network dynamic operation model; constructing a river water storage model a lake water storage model based on the watershed network dynamic operation model; constructing a distribution network linear alternating-current (AC) power flow model and an operating power-flow rate operation model of the pump stations to obtain a coordinated operation model of the urban distribution network and the watershed network; constructing a watershed-electricity composite sensitivity matrix; quantifying a time-varying adjustable power domain of each pump station through a pump station flexibility assessment method based on the watershed-electricity composite sensitivity matrix; constructing a power flow optimization model of the urban distribution network and a hydraulic energy flow optimization model of the watershed network; and performing electricity-water energy flow interactive optimization involving a flexible resource of the pump stations.

Techniques and apparatus presented herein are directed to improvements in maintaining voltage and frequency stability of an electric power delivery system. To do so, model predictive control (MPC) may be used. Input data may be obtained for a sampling period and may include a current system state. The MPC may predict an initial trajectory of the input data, output data, and a state of the system for a prediction period. The MPC may linearize the output and state trajectories and determine an updated input trajectory based at least in part on the linearized output trajectory. The MPC may determine control inputs to the system which achieve the updated input trajectory for a control period. The MPC may transmit control signals based at least in part on the control inputs to equipment associated with the input data.
