HEBR

This project implements the method of hierarchical electricity-theft behavior recognition proposed in [1], which is an algorithm for detecting electricity theft.

Testing

This project is implemented in Python 3.6

Dependency:

• Python 3.6. Version 3.6.2 has been tested.
• Tensorflow. Version 1.2.0 has been tested. Note that the GPU support is encouraged as it greatly boosts training efficiency.
• Other Python modules. Some other Python module dependencies are listed in requirements.txt, which can be easily installed with pip pip install -r requirements.txt

Testing the Project:

python run.py -f ./data/ -o ./data/result.csv

Usage

Given an array of multi-source time series data, including users' electricity records, non-technical losses in transformer area, temperature records, this program can be used to estimate the electricity-theft probabilities for users.

Input Format

The input files are expected to be four parts:

(1) Electricity Usage Records: a CSV file, which contains daily records for every user: #userID, #areaID, #date, #total electricity, #top electricity, #on-peak electricity, #flat electricity, #off-peak electricity.

(2) Non-Technical Loss Records: a CSV file, which contains daily records for every area: #areaID, #date, #cost electricity, #billed electricity, #lost electricity. Here, the areaID corresponds to the areaID in (1)

(3) Temperature Records: a CSV file, which records daily weather, containing #areaID, #data, #high temperature, #low temperature. We can spider the data by the code in ./data_factory/temperature_spider.py

(4) Labels of Electricity Thieves: a CSV file, which records the time that the electricity thieves are caught, containing #userID, #areaID, #date.

Output Format

The program outputs to a file named result.csv which contains the results of electricity-theft probabilities estimated by HEBR.
