A measurement device that performs a predetermined measurement task together with a plurality of other measurement devices is provided. This measurement device is provided with a sampling phase generator for generating a sampling phase for instructing a timing of sampling, and a communication unit for communicating with at least one of the plurality of other measurement devices. The communication unit transmits the sampling phase generated by the sampling phase generator to at least one of the plurality of other measurement devices. The sampling phase generator is configured to generate a third sampling phase, using an operation that is based on a generated first sampling phase and a second sampling phase received by the communication unit from at least one of the plurality of other measurement devices.

In an electrical apparatus, a power consumer consumes power. A request acquirer acquires a request for reducing power consumed by the power consumer. Upon the request acquirer acquiring the request, a power controller controls the power consumer based on at least one of environmental information relating to an ambient environment of the electrical apparatus, apparatus information relating to the electrical apparatus, or time information, to reduce the power.

A computer-implemented method and system is provided. The system manipulates load curves corresponding to time-variant energy demand and consumption of a built environment. The system analyzes a first, second, third, fourth and a fifth set of data. The first set of data is associated with energy consuming devices. The second set of data is associated with an occupancy behavior of users. The third set of data is associated with energy storage and supply means. The fourth set of data is associated with environmental sensors. The fifth set of data is associated with energy pricing models. The system executes control routines for controlling peak loading conditions associated with the built environment. The system manipulates an optimized operating state of the energy consuming devices. The system integrates the energy storage and supply means for optimal reduction of the peak level of energy demand concentrated over the limited period of time.

A modular monitoring and control system for NEMA-style load center smart electrical distribution panels is built up from interconnectable modules, starting with a Base Unit for monitoring and reporting on select branch circuits, then adding a Control Module for Remotely Operated breakers or additional current monitoring or both; and/or adding a separate Expansion Module with Current Transformer expansion capabilities for adding a larger number of power monitors within the load center. The modules plug into breaker pole slots within the panel for ease of installation and are independent of the breakers. The system keeps initial smart panel costs low by placing monitoring and control functionality and required parts into add-on modules.

In the battery control system pertaining to the present invention, one antenna is provided for each cell controller or each group of cell controllers. A battery controller switches between antennas by using a switch and performs wireless communication with each cell controller or each group of cell controllers. Hence, even if the number of cell controllers increases, a countermeasure can be taken by adding antennas and changing switches, and an increase in the number of battery controllers can be suppressed.

A system may include a device including a sensor configured to measure a parameter of a resource distributed along a distribution line of the resource distribution system and one or more validation devices. Each validation device includes a sensor configured to measure the parameter of the resource distributed along the distribution line or a related parameter. When the device detects that the parameter is out-of-range condition, it sends a query to the validation devices requesting information on the parameter or the related parameter. When the information regarding the parameter or related parameter also indicates an out-of-range condition, then the system validates the out-of-range condition. After validating the condition, the system may control a resource regulation device to adjust the parameter.

A modular photovoltaic (PV) array system includes a PV array installed onto a fleet vehicle such as a trailer, bus etc., a host control system into which a plurality of fleet vehicles can connect to collectively generate electricity, and a subscriber system which collectively tracks energy generation and allocates respective contributions to the system.

A personal power plant stores energy at the load site from renewable sources and through connection with a utility, enabling the personal power plant to support real time or near real time system load balancing and to eliminate net-metering. The personal power plant determines a charging profile based on predicted energy usage for a next 24-hour period. The personal power plant can provide an indication of the excess amount of electrical energy stored, but not needed for the next 24-hour period. When times of high demand are anticipated, the utility can reallocate energy to other users which it would otherwise provide to participating personal power plants aggregating the excess energy from a plurality of personal power plants. At such times, inverse power generation occurs as the personal power plants do not draw power from the grid which, in aggregation, reduces grid load.
