Present invention concerns charging of a power source of a device. A power usage pattern collector is configured to: collect data on power usage in a device, power source of which is chargeable, with regard to at least one particular criterion having influence on power usage in the device; and determine at least one power usage pattern by use of the collected data, said power usage pattern specifying power usage in the device with regard to at least one particular reoccurring criterion. A charging controller is configured to: acquire at least one power usage pattern; and control charging of a power source of a device by use of the at least one acquired power usage pattern. Present invention relates also to corresponding methods, correspondingly arranged computer program products, correspondingly arranged computer-readable recording media, and a system comprising the power usage pattern collector and the charging controller.

A control system for and a method of fault isolation and electrical power restoration on an electrical network are provided and comprise: a plurality of electrical power supply facilities connectable to a region of a network, the region comprising a plurality of segments, and each segment being connectable to one or more neighbouring segments by a respective switching device; and the method including the steps of: detecting a fault condition within the region; operating the plurality of switching devices connecting the segments within the region so as to disconnect those segments from one another; performing a reconnection routine for each of a plurality of reconnection zones, being run concurrently.

A system includes a control unit having one or more processors and a communication interface. The communication interface is configured to communicate with one or more charging stations that are electrically coupled to receive electrical power from a power distribution grid and that are configured to selectively charge one or more energy storage devices connected to the charging stations. The one or more processors are configured to generate first control signals for communication by the communication interface to the one or more charging stations to control transfer of reactive and/or active power from the charging stations to the power distribution grid. The control signals are generated based at least in part on a load cycle profile of one or more electric machines electrically coupled to the power distribution grid.

Methods and systems are provided for managing environmental conditions and energy usage associated with a site. One exemplary method of regulating an environment condition at a site involves a server receiving environmental measurement data from a monitoring system at the site via a network, determining an action for an electrical appliance at the site based at least in part on the environmental measurement data and one or more monitoring rules associated with the site, and providing an indication of the action to an actuator for the electrical appliance.

Computer software and a system are disclosed to provide group control and network operations to/for a multiplicity of distributed energy storage units. The group control software and system can connect multiple individual distributed energy storage units and operate those units in synchronicity to create a large virtual energy storage device. Methods of controlling the distributed energy storage units include: a browser-based online user portal, or network-based, system-to-system protocols by third-party operation controllers.

[Problem] As compared with the case where the apparent power in the electric line on the supply side is adjusted without supplying the current to the electric line closer to the power supply side than the distribution transformer, there is a reduction in the effect of the state in the electric line closer to the power reception side than the distribution transformer on the adjustment of the apparent power in the electric line closer to the power supply side than the distribution transformer.

[Solution] A power control system includes a device that receives power from an electric line of a distribution system via a distribution transformer, an acquisition unit that acquires electric line information on the electric line, and a control unit that causes the device to generate a current used for adjustment of apparent power in the electric line based on the electric line information acquired by the acquisition unit.

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.
