Methods and systems identify connection paths between a power source and a plurality of loads. A reachability signal is sent on a cable connecting a power output of the power source to a power distribution unit (PDU). The PDU receives the reachability and forwards a modified reachability signal on one or more power outputs of the PDU to one or more loads. The PDU receives a return reachability signal from the one or more loads and forwards corresponding modified return reachability signals on the cable to the power source. The power output of the power source receives a plurality of modified return reachability signals that each comprises an identity of the PDU, an identity of a respective power output of the PDU, and an identity of a respective load. A reference between these identities is stored by the power source in a database.

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.

An offshore oil and gas platform has a power supply system with a cascaded arrangement for a black start. The power supply system includes a first power supply apparatus for providing power at a first energy level, an uninterruptible power supply arrangement configured to receive power from the first power supply apparatus, wherein the uninterruptible power supply is for powering at least one essential and/or safety critical component, and a second power supply apparatus for providing power at a second energy level to a main power distribution system, wherein the second energy level is higher than the first energy level, wherein the second power supply apparatus includes a power source and a high-power energy storage system capable of supplying power at the second energy level, and wherein the second power supply apparatus can receive and store energy from the first power supply apparatus.

A master controller controls a plurality of uninterruptible power supply apparatuses each including a slave controller and detection circuits that detect at least a DC input voltage, an AC output voltage, and an output current of an inverter. The master controller generates a first voltage command value and a second voltage command value common to the plurality of uninterruptible power supply apparatuses based on detection values from the detection circuits transmitted from the slave controller of each of the uninterruptible power supply apparatuses. The master controller transmits the generated first and second voltage command values to the slave controller of each of the uninterruptible power supply apparatuses. The slave controller generates a first control signal for controlling a converter in accordance with the received first voltage command value. The slave controller generates a second control signal for controlling the inverter in accordance with the received second voltage command value.

A system includes an uninterruptible power supply (UPS) configured to selectively provide power to a critical load from a grid and an energy storage device, and a grid edge controller configured to communicate with a controller of the UPS and to cause the UPS to operate the energy storage as a distributed energy resource (DER) for the grid while preserving autonomous operation of the UPS to serve the critical load. The grid edge controller may be configured, for example, to maintain a critical reserve in the energy storage device that enables the UPS to maintain the critical load, while allowing the energy storage device to also be used for demand management, frequency regulation and other grid-oriented tasks. The grid edge controller may be configured to control the UPS, for example, via an application programming interface (API) of the controller of the UPS.

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.
