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).

Methods and systems for automatically checking an operational status of electrical components of an elevator system, the methods including setting a first power state of all addressed electrical components of the elevator system, measuring a control value power consumption with a power consumption counter, switching a first addressed electrical component into a second power state, monitoring a power consumption associated with the first addressed electrical component, comparing the power consumption associated with the first addressed electrical component with the control value power consumption, and when the power consumption associated with the first addressed electrical component is not greater than the control value power consumption, performing a detected failure operation.

Load disaggregation is useful for both the consumers and producers of energy. The present-day supervised learning models for load disaggregation necessitate the learning of models for every appliance load of interest, which incurs high computational costs. Embodiments of the present disclosure implement a Restricted Boltzmann Machine (RBM) based source-separation model with application to load disaggregation of appliances of interest. Representations of appliance of interest are learnt, between the power aggregate data and the appliance signatures, to output the mapping of data representations on the appliance signatures, for load disaggregation. Discriminative ability for each load/appliance of interest is achieved by adding the free energies of softmax layers of the RBM on other loads/appliance, as a discriminating gradient to the approximate gradients obtained on the load under consideration.

The present disclosure relates to methods and systems for managing and controlling resources. A system for managing and controlling resources may comprise a storage device configured to store a set of instructions, one or more processors configured to communicate with the storage device. When executing the set of instructions, the one or more processors may be configured to cause the system to collect resource usage data through one or more meters, process the resource usage data based on a preset algorithm to determine resource usage state, and control at least the one or more meters and/or one or more smart devices to perform specified operations based on the resource usage state. The present disclosure provides methods and systems for managing and controlling resources based on meters or smart devices controlled by the network.

Certain aspects and features include a system and method for validating fundamental-only power measurements. A meter testing application calculates an expected registration for a meter under test by comparing a fundamental demand indicating an amount of power expected to be delivered by the fundamental component to a known load with a wideband demand indicating an amount of power expected to be delivered by the wideband voltage to the known load. The application further measures, from the meter under test, a measured registration by applying the wideband voltage component and the known load to the meter under test, which is configured to measure power consumption from the fundamental component only. The application calculates based on the expected registration and the measured registration, an error for the meter. When the error is outside a tolerance, the application identifies the meter under test as non-compliant.
