A method for detecting non-technical losses in an electrical power system includes measuring an area under a squared RMS current curve for a power cable in the electrical power system over at least one time interval, measuring an active and a reactive energy for the power cable over the at least one time interval, and characterizing a cable reactance and a cable resistance using the active energy, the reactive energy, and the area under the squared RMS current curve. The method further includes determining an active energy loss and a reactive energy loss over the at least one time interval using the area under the squared RMS current curve and the reactance and the resistance of the cable, and detecting a non-technical loss in the electrical power system based on the active energy loss and the reactive energy loss over the at least one time interval.

Method and system to detect non-technical losses in an electrical power system

Detection and correction of technical and non-technical errors in smart grid power distribution are described. A system, method and non-transitory computer readable medium having instructions stored therein that, when executed by one or more processors, causes the one or more processors to perform a method for detecting and correcting technical and non-technical power losses in a smart grid that feature the following functions: remotely characterizing and updating the cables impedances, detecting and classifying the types of losses, estimating the technical and non-technical power losses when a check or smart meter is in error, estimating losses due to tapping a power cable by a registered or an unregistered user, and estimating losses due to a cyber attack. Technical errors corrected are impedance and reactance losses in the power distribution. Non-technical errors identified and corrected are no error, check meter in error, smart meter in error, tapping service cables, or cyber attacks.

Accurate detection and correction of technical and non-technical losses using smart metering

A system, method, and computer-readable storage medium for charging management for electric vehicles performing vehicle-to-grid regulation are presented. The system includes an aggregator that communicates with the electric vehicles according to a dispatch strategy to switch charging with electric power from the electric grid. The aggregator that aggregates and manages charging of a set of electric vehicles associated with an electric grid. A dispatch controller controls switching of at least a subset of electric vehicles of the set of electric vehicles between an ON state and an OFF state at a given time by sending binary charge commands to the subset of batteries, in a manner that change of charging rate of individual batteries is minimized while maintaining charging fairness among the respective electric vehicles.

Optimal dispatch of electric vehicles performing V2G regulation

The autonomous charging management system for electric vehicles utilizes a voltage feedback control structure that compares the system voltage at the point of charging against a reference, while also taking into account the EV battery state of charge (SOC). A proportional control structure reduces the EV charging as the system voltage approaches the reference. Moreover, the control structure does not require any communication between the EV and the utility.

The memory polynomial based digital predistorter utilizes a cluster-based particle swarm optimization (PSO) technique and has an embedded model-size estimator. The PSO technique and model-size estimator efficiently find the dimensions and accurately estimate the coefficients of the memory polynomial based digital predistorter for improved linearity of a power amplifier.
