A power management device for intelligently splitting and controlling a high power outlet is described. The device includes a housing, power input, outlets, power sensor, and a controller. The housing has an internal compartment configured to hold components of the device and an exterior surface. The device has a plurality of outlets on the exterior surface of the housing. Each outlet is configured to connect to an appliance. Each outlet has a power sensor configured to sense current draw and/or power use at the outlet. The controller of the device is contained within the internal compartment of the housing and monitors the usage of each outlet via readings from the power sensors. The controller determines, based on the monitored usage and appliance parameters, one or more outlets to provide current to, and causes current to be provided to the determined outlet(s).

An aircraft propulsion system includes at least first and second electrical generators, each being configured to provide electrical power to a respective first and second AC electrical network. The system further comprises at least first and second AC electrical motors directly electrically coupled to a respective AC network and coupled to a respective propulsor, and a DC electrical network electrically coupled to the first and second AC networks via respective first and second AC to DC converters, and to a further electrical motor, the further electrical motor being coupled to a propulsor.

Disclosed is an all-in-one emergency shed that can supply electricity and potable drinkable water during an emergency when electrical grid power is not available and water sources may be contaminated. The emergency shed can use battery banks from electric cars to store electrical energy for emergencies and can store electrical energy in electric car battery banks that are charged during off-peak times and resold to the utility company during peak demand periods.

An air conditioning device includes an alternating current (AC) bus, a direct current (DC) bus, a first AC/DC circuit, a first DC/AC circuit, and a backup power supply apparatus. The AC bus is connected to two power supplies through a switching circuit. The backup power supply apparatus is connected to the DC bus or the AC bus. The backup power supply apparatus provides electric energy for the DC bus or the AC bus when the two power supplies are switched or fail, so that the first air conditioning load is not powered off. The backup power supply apparatus may supply power to the load when the two power supplies are switched or fail.

A DC power feeding device includes a power feed line connected to a DC load, a first DC/DC converter provided between a solar battery and the power feed line, and a second DC/DC converter provided between a battery and the power feed line. A first controller controls the first DC/DC converter such that maximum power tracking control of the solar battery is performed in a normal state of a commercial AC power source. The first controller controls the first DC/DC converter such that the solar battery outputs a power smaller than a load power in a power failure. A second controller controls the second DC/DC converter such that the battery is charged in the normal state of the commercial AC power source. The second controller controls the second DC/DC converter such that DC voltage on the power feed line attains a reference voltage in the power failure.

A hydraulic fracturing system includes one or more battery trailers having one or more batteries for providing operational energy to one or more connected components. The system also includes a switchgear system and fracturing equipment to receive operational energy from the one or more batteries of the one or more battery trailers to perform one or more fracturing actions.

Methods for implementing power delivery transactions between a buyer and a seller of electrical energy supplied to an electrical grid by an integrated renewable energy source (RES) and energy storage system (ESS) of a RES-ESS facility are provided. Estimated total potential output of the RES is compared to a point of grid interconnect (POGI) limit to identify potential RES overgeneration, and the buyer is charged if potential RES overgeneration is less than potential overgeneration during one or more retrospective time windows. The method provides a basis for the RES-ESS facility owner to be paid for an estimated amount of energy that did not get stored as a result of a grid operator not fully discharging an ESS prior to the start of a new day.

A method of generating a customized secondary power distribution assembly (SPDA) includes generating one or more customizable SPDAs. Each of the one or more customizable SPDAs is a construct corresponding with a microprocessor configured to control a set of customizable channels in each of a set of virtual line replaceable modules (vLRMs). The method also includes creating a mapping between one of the one or more customizable SPDAs and the customized SPDA, the mapping indicating line replaceable modules (LRMs) of the customized SPDA and defining each channel of each LRM, and deploying the customized SPDA in an application. The microprocessor is initiated to control the customized SPDA according to the mapping at startup.

A power conditioner includes a PV converter that generates an output voltage, which is obtained by boosting a direct-current voltage input from a solar panel, an inverter that converts the output voltage of the PV converter into an alternating-current voltage, and a first relay connected between the inverter and a commercial power system. A controller includes a control circuit that controls the entire power conditioner, a control circuit that controls the PV converter, and a control circuit that controls the inverter. In a start process, the control circuit controls activation and deactivation of a DC-DC converter and causes the impedance of a DC-DC converter to change. The control circuit detects an input voltage and an input current of the PV converter and determines whether or not the first relay is to be in a close state according to those values.

An electrical distribution system includes a distributor designed to distribute an electric current in an electrical installation, the distributor being configured to be connected to a distribution grid, to at least one secondary electrical power supply source and to a plurality of the electrical loads . An electronic control device is configured to manage power supply parameters of at least some of the electrical loads to reduce the electric current consumed and/or to manage operating parameters of at least some of the secondary electrical power supply sources in order to reduce the electric current delivered by these sources, so as to comply with a current threshold dictated by a protection element and/or by the distributor .
