The present disclosure relates to a power supply management system adapted for use with at least one utility proxy power source, to help control powering a load when an AC mains power source is not available to provide power to the load. The system has a power converter forming an uninterruptible power supply, and includes a controller configured to control operation of the power converter. A supplemental battery subsystem is included which is in communication with the power converter for supplying DC power to the power converter. The controller monitors the application of power from the utility proxy to the load and uses the DC power supplied by the supplemental battery subsystem, when needed, to supplement the generation of power by the power converter, to thus assist the power converter in powering the load along with the power being provided by the utility proxy.

A system includes an electrical apparatus configured to monitor or control one or more aspects of an electrical power distribution network; and a control system including more than one electronic processor, where the electronic processors are configured to cause the control system to interact with the electrical apparatus, an interaction between the control system and the electrical apparatus including one or more of the control system providing information to the electrical apparatus and the control system receiving information from the electrical apparatus, and if some of the electronic processors are unable to cause the control system to interact with the electrical apparatus, at least one of the other electronic processors is able to cause the control system to interact with the apparatus.

Systems and methods for efficient power conversion in a power supply in a power distribution system are disclosed. In particular, a low frequency transformer having high conversion efficiency is coupled to an input from a power grid. An output from the transformer is rectified and then converted by a power factor correction (PFC) converter before passing the power to the distributed elements of the power distribution system. By placing the transformer in front of the PFC converter, overall efficiency may be improved by operating at lower frequencies while preserving a desired power factor and providing a desired voltage level. The size and cost of the cabinet containing the power conversion circuitry is minimized, and operating expenses are also reduced as less waste energy is generated.

Systems, apparatuses, and methods are described for a backup system. The configuration of the backup system in terms of number of load groups, power sources, and/or total power limit may be altered. An interface enclosure of the backup system may include a housing for electric circuitry, where the housing may be a clam-shell design including a base plate and a backup interface module. The base plate may comprise a frame, one or more detachable hinges, and/or two or more multi-terminals. The base plate may include a plurality of multi-terminals. The multi-terminals may be arranged to connect to one or more load groups, power sources, power devices, other multi-terminals, etc. Each load group that is connected to the multi-terminals may be disconnected from the utility grid and connected to the one or more sources of backup power in the case of a utility grid shutdown.

A controller circuit for a PV module includes a receiver circuit and a mode control and power conversion circuit. The receiver circuit receives a first signal from a transmitter circuit associated with the PV module. The receiver circuit changes a second signal from a first state to a second state based the first signal. The mode control and power conversion circuit receives a DC string voltage from a string of PV cells associated with the PV module, receives the second signal from the receiver circuit, switches from a first mode to a second mode in response to the second signal being changed to the second state, converts the DC string voltage to a standby voltage in the second mode, and provides the standby voltage to DC power lines between the PV module and a DC-to-AC inverter in the second mode.

The analysis processor provided in the energy storage device can analyze, through learning, power consumption patterns, environmental information, and/or disaster information, control the charging speed and/or charging amount of the energy storage device on the basis of such learning data, and control output according to the priority of the load device.

A method, system and apparatus are provided for optimized load shaping for optimizing production and consumption of energy. Information signals indicative of a first load shape signal are obtained corresponding to a total load, a renewable energy load of one or more renewable energy sources and a non-renewable energy load of one or more non-renewable energy sources. The first load shape signal corresponding to renewable energy load is removed from a non-renewable energy load to obtain a resulting load shape signal. The resulting load shape is flattened signal by apportioning the resulting load shape signal across time intervals to obtain a flattened load shape signal. At least a portion of the first component corresponding to the renewable energy load is added to the flattened load shape signal to create an optimized load shape signal. The optimized load shape signal is provided to modulate electric loads of energy-consuming devices.
