Method and apparatus for load identification
A load communication device and method is provided, that identifies and transmits to a PSU the load requirement to operate a load device that is powered by the PSU, by analyzing the characteristics of current applied to the load device by a given input voltage generated by the PSU. The load communication device is configured to transmit between the PSU and the load device solely over the 2 wire cable that extends between the PSU and the load device.
Power consumption analyzing server and power consumption analyzing method thereof
A power consumption analyzing server and a power consumption analyzing method thereof are provided. According to the user data, the power consumption analyzing server clusters users into a plurality of groups. For each group, the power consumption analyzing server generates M+1 number of encoded outputs by inputting total power consumption time sequence data corresponding to a reference user in the group into an autoencoder. For each group, the power consumption analyzing server receives an actual appliance measurement data from an energy management system apparatus of the reference user, and labels M number of encoded outputs of the M+1 number of encoded outputs to map them to M categories of appliances. Finally, for each group, the power consumption analyzing server establishes a non-intrusive load monitoring system model of the group.
Energy disaggregation techniques for low resolution whole-house energy consumption data
The present invention is generally directed to methods of disaggregating low resolution whole-house energy consumption data. In accordance with some embodiments of the present invention, methods may include steps of: receiving at a processor the low resolution whole house profile; selectively communicating with a first database including non-electrical information; selectively communicating with a second database including training data; and determining by the processor based on the low resolution whole house profile, the non-electrical information and the training data, individual appliance load profiles for one or more appliances.
AUTOMATIC SYSTEM FOR MONITORING ELECTRIC POWER CONSUMPTION
A system for managing devices supplied through a power grid is proposed. Each device is configured to consume over time electric power according to at least one respective power profile when operating. The system comprises at least one unit interfaced with the devices for exchanging data. The at least one unit collects power profile data indicative of the power profiles of the devices, and generates a time schedule of the device operations by distributing over time start times of the power profiles in such a way that at any time the total power consumption of the devices is kept under a maximum power threshold of the power grid.
DISCOVERING UPGRADE TO INCREASE CAPACITY FOR SUPPORTING ELECTRICAL LOAD AT PARTICULAR LOCATION OF POWER GRID
A system can obtain data that is sourced from an operator of a power grid and includes data items provided on a per-segment basis for feeders. The system can branch the data items into respective feeder groups and generate a data structure based on an adjacency map for segments of a feeder group. The system can construct a feeder load profile based for a feeder on the ordered data structure. The feeder load profile depicts a load capacity for the feeder as a function of a distance from the substation. The system can then determine, based on the feeder load profile, that an available load capacity at the interconnection point is below a threshold required to support an electric vehicle (EV) charging station and identify upgrades based on variations in the feeder load profile to support the EV charging station.

The device and method prevent accurate identification of powered devices, their presence, their operating characteristics, their consumption data, and any inferences of power device user's behaviors and activities by the analysis of disaggregated data. The operation of the device may include any of a range of steps, actions and instructions to introduce altering impedance elements and filtration circuits in coordinated fashion with the operation of the targeted devices to be masked.
DISAGGREGATION AND LOAD IDENTIFICATION OF LOAD-LEVEL ELECTRICAL CONSUMPTION FOR AUTOMATED LOADS
A disaggregation and identification method arranged to disaggregate and identify aggregated electrical load data. The method comprises obtaining operation data from an automated control management system; extracting a timing sequence from the operation data for each load in the automated system; storing each timing sequence in a datastore; streaming aggregated power data from a load center associated with the system, wherein the power data comprises measured electrical signals; and recording time stamps for each new event measured from the streamed aggregated power data, wherein an event is a change in power signal at a load. The method further comprises performing nearest neighbour comparison of the recorded power time series data to the timing sequence of the operation data; mapping each event timestamp to the nearest time sequence; classifying the load according to the mapped time data; and storing the classified load profile in a datastore.
Power Tool Pack Adapter Having Audio and Video Components
Adapters for a power tool are backwards compatible with a variety of different power tools, battery packs, and other power tool devices. The power tool pack adapter fits between a power tool and a battery pack (or other such power tool devices) and provides extra functionality (e.g., voice control, cameras, machine learning, etc.) to a power tool or other power tool device. The added functionality can be implemented by a dedicated electronic controller and/or processor in the power tool pack adapter.
