A rapidly deployable modular microgrid including a plurality of renewable and other energy generation technologies, energy storage technologies, energy distribution networks, and intelligent control systems capable of managing the flow of electrical energy between one or more locations of energy generation, storage, and consumption are disclosed. The aforementioned microgrid may be delivered and rapidly deployed to provide primary or secondary electricity for a variety of purposes; including but not limited to household electrification, commercial or industrial productivity, grid resiliency, water pumping, telecommunication systems, medical facilities, and disaster relief efforts.

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 another embodiment, the energy storage unit is integrated into the chassis of an appliance itself.

The invention is related to a method for controlling an electrical installation from a remote control station, the electrical installation comprising a coupling network 5 powering one or more electrical loads 7, 8, a main switch 13 to connect a main power source 10 to the coupling network 5 and an auxiliary switch 23 to connect an auxiliary power source 20 to the coupling network 5.

The control method comprises a first step for synchronising the auxiliary power source 20 with the main power supply source 10 comprising a phase of measuring electric data relative to the main power supply source and to the auxiliary power source and a verification phase, from the remote control station, to ensure that the measured electric data relative to the main power supply source and the auxiliary power source is compatible, a step to send an order to close the auxiliary switch 23 from the remote control station, a step to send an order to open the main switch 13 from the remote control station and a checking step, from the remote control station, that the loads 7, 8 are correctly powered by the auxiliary power source.

An externally-controllable electrical power generating system for providing auxiliary or backup power to a load bus or device. The system may be used indoors, and generally includes a power source comprising a first DC output, an electrical storage unit comprising a DC input coupled to the first DC output of the power source, the electrical storage unit further comprising a second DC output. An inverter coupled to the second DC output receives power, the inverter having a first AC output that can be synchronized with an AC load bus or AC grid. The system includes a contactor connected between the first AC output and an AC load bus, and is controllable with an external controller operated by a utility or a managing entity, such that the external controller can enable the controller to connect or disconnect the contactor.

A micro-network includes at least two heating appliances with communication modules, one being used for obtaining and transmitting a first data set having at least one measurement related to the electricity consumption of the heating appliance, at least one measurement related to the electricity production of same and at least one measurement related to a state of charge of an electrical energy storage device, and subsequently controlling the power supply to the heating member. The other module is used for obtaining, and transmitting to a supervision module, first and second data sets including at least one item of data relating to an electrical power source, and subsequently transmitting a first setpoint state of charge related to the state of charge of the electrical energy storage device of the other heating device. The first setpoint state of charge is taken into account when controlling the power supply to the heating member.

The first power storage unit includes multiple first battery assemblies connected in series, and a respective first battery assembly has at least one secondary battery. The first detection unit includes multiple first detectors. The first data transmission unit includes a first one-way transmit port and a first two-way transmit port. The sub battery module includes a second power storage unit, a second detection unit, a second processing unit, and a second data transmission unit. The second power storage unit includes multiple second battery assemblies connected in series. The second detection unit includes multiple second detectors.

An example system includes an aggregator configured to receive a service collaboration request and iteratively determine, based on minimum and maximum power values for DERs under its management, an optimized operation schedule. The aggregator may also be configured to iteratively determine, based on the optimized operation schedule, an estimated flexibility range for devices under its management and output an indication thereof. The system may also include a power management unit (PMU) configured to iteratively receive the indication and determine, based on a network model that includes the estimated flexibility range, a reconfiguration plan and an overall optimized operation schedule for the network. The PMU may also be configured to iteratively cause reconfiguration of the network based on the plan. The PMU and aggregator may also be configured to iteratively, at a fast timescale, cause energy resources under their management to modify operation based on the overall optimized operation schedule.

Various implementations power homes and businesses without needing to connect to electric utility company-provided power, i.e., they can operate off-grid. Generally the system includes solar panel racks (e.g., photovoltaic cells on sheets stabilized using ballasts, anchors, or mounting) that generate electrical power used to provide power to a building or that is stored on batteries. The system includes the solar panel racks and an enclosure to be installed at the premises and separate from the building. The enclosure includes the batteries and inverters that are electronically connected to the solar panel racks and batteries. The inverters are configured to convert direct current (DC) electricity from the solar power racks and batteries to alternating current (AC) electricity to provide power to the building via wires electrically connecting the inverters to the main panel of the building.
