A smart switching panel for selectively connecting either a primary power supply or a secondary power supply to a plurality of electric loads. The switching panel includes a plurality of switching elements each connected to both the primary and secondary power supplies. A controller of the switching panel operates to cause the switching element to transition between a first position in which the primary power supply is connected to the electric load, a second position in which the secondary power supply is connected to the electric load and an open condition. A current sensor is positioned to monitor the amount of current drawn by the electric load and is connected to the controller such that the controller can monitor the amount of current drawn by each of the electric loads. The controller can transition each of the switching elements to the open condition when the current draw exceeds a current threshold.

As an improvement to existing matrix-like power/communications systems, a decentralized array of power and communications components defining a self-configuring modular electrical system which is comprised of components that are completely scalable, easily replaceable, intelligent and combinable in a series, parallel, bypassed state or even capable of elegantly switching in a spare cell(s) to replace a dead cell while interfacing with common battery power chemistry, an external power supply input, a standardized bi-directional data communication input and is combinable and arrangeable into practically any mechanical footprint whereby energy density and communications capability is maximized along with simplicity in accordance with weight and balance considerations and integrated as an autonomous system at the lowest possible cost while being survivable in the harshest of environments including physical shock, vibration, vacuum, radiation, thermal, and electromagnetic interference and providing a communications interface for external control or monitoring via human or other control system input while simultaneously being capable of fully and simply reconfiguring itself if an internal battery cell failure occurs within the system, allowing for instant stabilization to maintain the required uninterrupted power output while providing uninterrupted communications through the system during the upset event while being instantly reconfigurable from series to parallel or vice versa ordering, and being capable of reconfiguring itself autonomously into an arrangement of series/parallel states within its architecture for charge/discharge while enabling cell balancing and continual monitoring all individual cell health status parameters, and only using two wires for all component interconnection.

Systems for providing operating reserves to an electric power grid are disclosed. In one embodiment, a system comprises at least one power consuming device, at least one controllable device, and a client device constructed and configured in network communication. The at least one controllable device is operably coupled to the at least one power consuming device. The at least one controllable device is operable to control a power flow from the electric power grid to the at least one power consuming device responsive to power control instructions from the client device. Each of the at least one power consuming device has an actual value of power reduced and/or to be reduced based on revenue grade metrology, and confirmed by measurement and verification. The actual value of power reduced and/or to be reduced is a curtailment value as supply equivalence and provides operating reserve for the electric power grid.

A coordinator manages communications between at least one server and the at least one power supply source, wherein the server is operable to initiate power commands, wherein the communications comprise an actual amount of power supply available for the electric power grid from the at least one power supply source, and wherein the at least one power supply source is operable to provide power supply to the electric power grid based on the power commands.

The present disclosure is directed to energy storage and supply management system. The system may include one or more of a control unit, which is in communication with the power grid, and an energy storage unit that stores power for use at a later time. The system may be used with traditional utility provided power as well as locally generated solar, wind, and any other types of power generation technology. In some embodiments, the energy storage unit and the control unit are housed in the same chassis. In other embodiments, the energy storage unit and the control unit are separate. In another embodiment, the energy storage unit is integrated into the chassis of an appliance itself.

A town storage battery power conversion device outputs an AC voltage to a distribution system during a power failure. Electric power generated by a solar cell installed in each consumer house is converted into an AC voltage by a solar cell power conversion device and output to a consumer premises distribution system to which a load is connected. In an autonomous operation during a power failure, an operation plan for a distributed power supply is updated in a cycle longer than a cycle of an operation plan for a town storage battery. In the autonomous operation, the town storage battery power conversion device changes an AC voltage frequency according to a difference between electric power output from the town storage battery and the operation plan. The solar cell power conversion device has a function of modifying a control target value for the solar cell according to the AC voltage frequency.

This disclosure describes techniques for identifying and mitigating a voltage loss in a power transmission to a Remote Radio Unit (RRU) associated with Radio Frequency (RF) antennas of a telecommunications network. More particularly, a Supplemental Voltage (SV) controller is described that is configured to monitor and detect a change in voltage that occurs during a power transmission from a primary Direct Current (DC) power source to the RRU and selectively cause a supplemental DC power source to transmit a supplemental voltage to the RF antennas. The SV controller may cause a supplemental DC power source to transmit a supplemental voltage to the RRU based on an empirical data analysis, sensory data analysis, or current environmental metadata. Further, the SV controller may determine whether the primary DC power source has suddenly ceased transmitting power to the RRU, and in doing so, cease transmission of a supplemental voltage to the RRU.

Power systems, devices, and methods include a plurality of network interfaces for providing communication to, e.g., a management server, console, or user interface. One or more controllers coupled to power circuitry determine whether a preferred one of the network interfaces has connectivity, and directs communication over the preferred network interface in response to a determination that the preferred network interface does have connectivity. The controller directs communication over an alternate one of the network interfaces in response to a determination that the preferred network interface does not have connectivity.
