In a wireless power supply system, a power transmitting apparatus wirelessly supplies power to an assigned power receiving apparatus. The wireless power supply system includes an assigning unit that assigns the power receiving apparatus to the power transmitting apparatus, and a determining unit that, when the assigning unit assigns a particular power receiving apparatus to a plurality of power transmitting apparatuses, determines a power supply schedule such that the plurality of power transmitting apparatuses supply the power to the particular power receiving apparatus, not simultaneously.

The methods and apparatus described enable automatic configuration, or commissioning, of controller devices and load control devices through a low voltage communication network controlled by one or more controller devices. These methods and apparatus further enable expansion of the load control system by connection of additional loads and or load control devices and or controller devices which will reinitialize the low voltage communication network and automatically reconfigure the controller devices and load control devices connected to the network.

The present disclosure provides energy control systems for whole home and partial home backup with integrated breaker spaces and metering. The energy control system includes a grid interconnection electrically coupled to a utility grid, a backup power interconnection electrically coupled to a backup power source, a backup load interconnection electrically coupled to at least one backup load, and a non-backup load interconnection electrically coupled to at least one non-backup load. The energy control system includes a microgrid interconnection device that switches between an on-grid mode to electrically connect the grid interconnection and the backup power interconnection with the backup and non-backup load interconnections and a backup mode to electrically disconnect the grid interconnection and the non-backup load interconnection from the backup power interconnection.

An apparatus for controlling components in a grid branch of an electrical power supply grid having a grid branch control unit for limiting a load in the grid branch, containing a grid state determination device, by means of which at least one physical parameter denoting a grid state of the grid branch is determinable, a control device for generating a control signal, by means of which an electric current between the grid branch and a component connected to a connection point thereof is influencable on the basis of the grid state, wherein the components have associated communication means for sending and/or receiving data and the control device of at least one of the components evaluates the determined parameters of the multiple components and takes the evaluation result as a basis for generating the control signals of the associated components of the same grid branch.

An asset manager controls power distribution within an aggregated distributed energy resources system (“DERs system”) having a plurality of assets. The asset manager is configured to operate with a given asset. As such, the asset manager has 1) an interface to receive asset information relating to the given asset and to communicate with another asset manager in the DERs system, and 2) a function generator configured to produce a local cost function using data relating to the given asset only. The local cost function represents a portion of a system cost function for the DERs system. The asset manager also has 3) a controller configured to use the local cost function for the given asset to manage operation of the given asset in the DERs system. In addition, the controller also is configured to determine, using the local cost function, an operating point for the given asset.

The methods and apparatus described enable automatic configuration, or commissioning, of controller devices and load control devices through a low voltage communication network controlled by one or more controller devices. These methods and apparatus further enable expansion of the load control system by connection of additional loads and or load control devices and or controller devices which will reinitialize the low voltage communication network and automatically reconfigure the controller devices and load control devices connected to the network.

A multi-port power delivery system includes a first universal serial bus (USB) port, a second USB port, a first power conversion unit, a second power conversion unit, a power delivery control circuit and a switch circuit. The first USB port is configured to output power delivered to a first power path. The second USB port is configured to output power delivered to a second power path. The first power conversion unit has a first output terminal coupled to the first power path. The second power conversion unit has a second output terminal coupled to the second power path. The power delivery control circuit generates a switch control signal according to first connection information on the first USB port and second connection information on the second USB port. The switch circuit selectively couples the first output terminal to the second output terminal according to the switch control signal.

An electrical distribution site energy management and router device, or SER device, may be installed between a customer premises and a distribution grid, and one or more alternative energy sources and energy storage devices may be electrically connected to the SER device. The SER device may intelligently route power from alternative energy sources to the customer premises, energy storage devices, even to the grid, through various modes of operation. The SER device may efficiently and economically route power during peak electricity price periods and outside of peak periods.

An electrical distribution grid energy management and router device, or GER device, may be installed in a distribution grid, and route power from power supply to one or more power consumers. The GER devices described herein may provide platforms to add one or more features to a distribution transformer, provide additional features and benefits to both the utility company and end consumer, and may serve as a platform for providing other features, such as communications services, local and remote management, and intelligence to components of the distribution grid. A GER device may include sensors to measure electrical properties of incoming and outgoing power, and may include an electrical circuit layer having a central DC power stage. A GER device may also include a communications platform for one or more communication devices to communicate with a utility, power consumers, other electrical devices/parties, and/or other GER devices to form a micro-grid.
