Abstract

On the basis of [1] and [2], this paper investigates the possibility of jamming the method of the detection of the hook style energy theft (HS-DET method) that is used for the detection of the hook style energy theft in the overhead low-voltage (OV LV) power grids. Three more sophisticated scenarios, which have been revealed in [2] and are the evolution of the three main suspicious issues of [1], are further investigated in this paper. The detection efficiency of HS-DET method is assessed by using the already validated percent error sum (PES) submetrics and appropriate contour plots. Citation: Lazaropoulos, A. G. (2019).

Highlights

The hook style energy theft detection method (HS-DET method), which has been proposed in [1] and partially tested on its detection performance during a set of special cases in [2], aims at detecting the hook style energy theft in overhead low-voltage (OV LV) power grids that exploit broadband over powerlines (BPL) technology conveniences
HS-DET method is added in the existing portfolio of BPL broadband applications, such as Topology Identification Methodology (TIM) [3], Fault and Instability Identification Methodology (FIIM) [4], methodology to preserve power system stability [5], [6] and main line fault localization methodology (MLFLM) [7]-[9], while its application is considered valid when all the problematic cases of TIM, FIIM and MLFLM are excluded
The robustness of decisions of HS-DET method is evaluated as well as the road map towards safer decisions concerning the detection of hook style energy thefts

Summary

Introduction

The hook style energy theft detection method (HS-DET method), which has been proposed in [1] and partially tested on its detection performance during a set of special cases in [2], aims at detecting the hook style energy theft in overhead low-voltage (OV LV) power grids that exploit broadband over powerlines (BPL) technology conveniences. If remains above the strict threshold, which is equal to 10%, a safe detection of a hook style energy theft can be received. If remains between the above the loose threshold, which is equal to 0%, and the strict threshold, a less safe detection of a hook style energy theft can be received. It should be noted that HS-DET method can give reliable decisions concerning the existence of the energy theft regardless of the existence of very intense measurement differences due to the definition that can significantly mitigate them (see [1] and Appendix of [2])
