The present disclosure provides a method and a system for the production and storage of electric energy. The method performed by a central control unit includes providing the power supply to a customer location from an electrical power supply system. The method further includes determining whether power supply is available from a remote power system. The availability of the power supply is determined based on determining whether electric power is being exchanged with an interface electrically connecting a gateway AC battery of the electrical power supply system to the remote power system. The method further includes charging and discharging of the AC batteries using power supply that is being exchanged between the gateway AC battery and the remote power system for providing power supply from the gateway AC battery to the customer location, and from photovoltaic panels equipped with AC/DC converters.

The present disclosure provides methods and systems for automatically controlling power supply from an electrical power supply system to a user location based on payment status. The method performed by a central control unit includes determining a payment status of the electrical power supply system at the user location. The payment status is determined based at least on a time credit associated with the electrical power supply system. The method further includes facilitating control of the power supply from the electrical power supply system to the user location based on determining the time credit. The power supply to the user location from the electrical power supply system is uninterrupted, if the time credit is greater than a predefined threshold value. The power supply to the user location from the electrical power supply system is disconnected, if the time credit is less than the predefined threshold value.

According to one embodiment, a BBU includes an array of battery cells, a DC/DC converter coupled to the battery cells, and a first switch logic coupled to the battery cells and the DC/DC converter. The first switch logic is configured to switch the BBU to operate between a first mode and a second mode. When operating in the first mode, the first switch logic causes the output voltage of the DC/DC converter to be provided to an external load. When operating in the second mode, the first switch logic causes the output voltage of the DC/DC converter to be coupled to an internal load for the purpose of determining the health of the battery cells.

A network power failure alert system for recognizing network outages and locating power failures includes a plurality of uninterruptable power sources, a plurality of location networks, and a data center. Each uninterruptable power source is configured to connect to an alternating current power source. Each location network comprises a site router and a plurality of switches. A power supply of the site router is in operational communication with the uninterruptable power source. Each switch is in operational communication with the site router and the uninterruptable power source. The data center comprises a primary core router in operational communication with the site router of each location network, the uninterruptable power source, and a plurality of network stations.

A power supply unit for an IED for LV or MV electric power applications characterized in that it comprises: a power transformer stage, which is operatively coupled to a feeding conductor to harvest electric power from said feeding conductor; a first storage stage, which is electrically connected to said power transformer stage to store electric energy; a first step-down conversion stage, which is electrically connectable/disconnectable to/from said first storage stage; a switching stage adapted to electrically connect/disconnect said first step-down conversion stage with/from said first storage stage; and a second storage stage, which is electrically connected to said first step-down conversion stage to store electric energy.

A power control system for managing energy transfer includes a shared electrical bus including an electrical energy generating source, an electrical energy storage device, and an electrical load, each connected to the shared electrical bus; and a controller operable to execute a plurality of instructions stored in a non-transitory memory on the controller to: receive a command corresponding to a desired operation of the power control system, generate a plurality of control commands as a function of a signal received from at least one sensor, and generate a log storing the present operating state for each of the electrical energy generating source, the electrical energy storage device, and the electrical load over a predefined duration, and wherein the at least one input corresponding to the past operating state of the power control system is the log.

Apparatuses including power electronics circuitry are provided. The power electronics circuitry includes at least one power converter that is coupled to a DC bus. Moreover, in some embodiments, the at least one power converter is configured to regulate a voltage of the DC bus. Related methods of operating an apparatus including power electronics circuitry are also provided.

A system of modules which control and measure energy usage at a building which are in communication with a software program executing on a remote server controlled by a third party. The third party said usage via the software program which communicates with the modules to modify energy usage and demand for energy and is responsible or liable for energy usage charges the building where the third party does not actually use the energy.

A remote drive with a support element for a top-hat-rail mounting. Opposing actuators disposed on the support element alternatingly act on a displaceably mounted slider by rod-shaped anchors. A slider passage receives a first lever arm of a rocker lever pivotable about a rotational axis parallel to the top hat rail length and nearly passes through a rotational point of a shift lever of a switching device. A carrier rail on a second lever arm is parallel to the top hat rail length, the shift lever engaging the carrier rail to the side of the second lever arm. When the slider is displaced, the rocker lever flips simultaneously activate the shift lever. In a remote drive assembly, two remote drives are disposed adjacent to one another on a top hat rail with a locking mechanism. Alternatively, individually controlled actuators act on first and second legs of a T-shaped rocker switch.

A cell and/or internet device that can be connected to existing city devices that are powered by city power to install a wireless cell and/or internet service to the city. The system has a plurality of the cell and/or internet devices connected to associated city devices powered by city power, and the cell and/or internet devices are controlled by a server. A method of using the system to provide cell and/or internet services to a city.
