Technology for mitigating impact of a power outage includes a method that determines power regulation data and identifies a power interruption event. The power interruption event is determined to disrupt operation of an electronic device powered by a grid power supply based on the power regulation data. The method mitigates the identified power interruption event by causing an electronic power supply device to transition from receiving power from the grid power supply to receive power from a local power supply where the electronic device is electrically coupled to the electronic power supply device.

An energy planning system that proposes an appropriate energy plan for a home includes: a sensor that senses a state of an energy facility in a home; a predictor that predicts a future lifestyle of a resident of the home; and a proposer that determines information about an energy plan for the home based on a result of the sensing by the sensor and the lifestyle predicted by the predictor, and outputs the information.

Systems and methods for distributed control and energy management of one or more communities of energy-consuming units may include aggregation of consumption data from units, and determining per-unit electricity consumption based thereon, including consumption of backup power provided by a community during periods of time of poor quality (brownouts) or blackouts of a utility. A system may calculate and assess to respective units per-unit costs for such backup power. A system may also issue a command or alert to units to carry out one or both of community electricity usage objectives and electricity quotas required by the utility, which may be determined through execution of rules.

A power interface device includes a first connecting module, a second connecting module and a processing module. The processing module performs the following: receiving a supply voltage through the first connecting module from a power supply device that employs a fast charging technology and that provides, based on an informing output, the supply voltage having a magnitude dependent on the informing output; generating the informing output; outputting the informing output to the power supply device through the first connecting module; and starting to output the supply voltage to the second connecting module when determining that a condition associated with the magnitude of the supply voltage is met.

A method of managing electric energy consumption and/or production dynamics, includes the steps of: sampling an electric energy flow, adapted to be measured by an electricity metering device (1) within a network (15) of an electrical company; calculating a variation ΔE.sub.i=(E.sub.i−E.sub.i−1)/Δt at regular intervals, where E.sub.i and E.sub.i−1 are two integral sum values of electric energy amounts consolidated over a given number of cycles and Δt represents a time interval between the respective times at which the two values are obtained; adding the variation (ΔE.sub.i) to analogous variations calculated at previous times, to obtain a cumulative sum of such variations; determining whether the variation and/or the cumulative sum exceed a predetermined threshold value (δ.sub.DE); transmitting a message over the network (15) from the electricity metering device (1) if the variation and/or cumulative sum exceed the predetermined threshold value (δ.sub.DE).

A method of analyzing events for an electrical system includes: receiving event stream(s) of events occurring in the electrical system, the events being identified from captured energy-related signals in the system; analyzing, an event stream(s) of the events to identify different actionable triggers therefrom, the different triggers including a scenario in which a group of events satisfies one or more predetermined triggering conditions; analyzing, over time, the different actionable triggers to identify a combination of occurring and/or non-occurring actionable triggers which satisfies a predefined trigger combination condition and an analysis time constraint; and in response to the observation of the combination, taking one or more actions to address the events. The analysis time constraint can be a time period duration and/or sequence within which time-stamped data of events in the event stream(s) and the associated actionable triggers are considered or not considered in the analysis to identify the combination.

Aspects of the subject disclosure may include, for example, embodiments detecting and correcting load imbalance on power supply phases within a managed scope using a software controlled power switch matrix that is resident in each power distribution unit supplying power in the managed scope.
