3. Abstract
The increasing demand for electricity has led to the growth of smart grids, which offer numerous
advantages such as improved energy efficiency, reduced power outages, and enhanced security.
However, one of the significant challenges in smart grids is electricity theft, which is a major cause of
revenue loss for utility companies. So, electricity theft is a major concern for electric power
distribution companies. The aim of this project is to develop an effective approach for detecting
electricity theft in smart grids based on Artificial Neural Network (ANN). The proposed approach will
use electricity usage dataset which is referred from the popular web repository kaggle. The collected
data will be preprocessed and fed into the ANN, which will learn to identify patterns and anomalies in
the consumption data. The ANN model will be trained using a dataset of legitimate consumption
patterns and then tested with data that contains instances of electricity theft. To evaluate the
performance of the proposed approach, the model will be tested on a test data. The results predicted
from our proposed system of electricity theft detection in smart grids using ANN is Good. Our system
achieved Training Accuracy of 99% and Validation Accuracy of 99%. The performance metrics used
will include accuracy, precision, recall, and F1-score. We also developed the proposed system in Flask
Web framework for easy usage with better User Interface for the predicting the results. The expected
outcome of this project is an effective approach for detecting electricity theft in smart grids using
ANN, which can be used by utility companies to improve their revenue collection and enhance the
security of the smart grid. This project can also be extended to other domains that involve anomaly
detection in large-scale datasets, such as fraud detection in financial systems and intrusion detection in
computer networks.

4. SYNOPSIS OF THE WORK
1. Relevance and Introduction:
The proliferation of smart grids has revolutionized the way electricity is generated,
distributed, and consumed. This modernization has brought about numerous benefits,
including enhanced energy efficiency, real-time monitoring, and demand response
capabilities. However, along with these advancements, the challenge of electricity theft has
also evolved, necessitating innovative solutions to safeguard the integrity of the power
distribution infrastructure.
Electricity theft, often referred to as "energy pilferage," is a significant concern for utility
companies and regulators worldwide. It involves unauthorized consumption of electricity
without proper billing, resulting in substantial financial losses and compromised grid
reliability. Traditional methods of detecting theft, which primarily rely on manual
inspections and rule-based algorithms, have proven inadequate in addressing the growing
sophistication of fraudulent practices.
To tackle this issue, there is a pressing need for more advanced and automated techniques
that can accurately identify instances of electricity theft in real time. This project proposes
the utilization of deep neural networks (DNNs) as a cutting-edge approach to electricity theft
detection in smart grids. DNNs have demonstrated remarkable capabilities in various
domains, including image recognition, natural language processing, and anomaly detection.
The fundamental premise of this project revolves around harnessing the power of DNNs to
analyze the voluminous data generated by smart meters and other sensors within the grid. By
capturing intricate patterns, correlations, and anomalies hidden within this data, DNNs can
provide a more accurate and efficient means of distinguishing between legitimate energy
consumption and fraudulent activities. This approach holds the promise of significantly
improving the accuracy and effectiveness of theft detection systems.
In this context, the following sections of the project will delve into the methodology, data
collection and preprocessing, DNN architecture design, and experimental results. By
addressing the challenges associated with electricity theft using a state-of-the-art technology
like DNNs, this project aspires to contribute to the advancement of smart grid security and
reliability, ultimately benefiting both utility providers and consumers alike.
