چکیده
Electricity theft is one of the challenging problems in smart grids. The power utilities around globe face huge economic loss due to ET. traditional electricity detection (ETD) models confront several challenges, such as highly imbalance distribution consumption data, curse dimensionality and inevitable effects non-malicious factors. To cope with aforementioned concerns, this paper presents a novel ETD strategy for grids based on attacks, long short-term memory (LSTM) gated recurrent unit (GRU) called TLGRU. It includes three subunits: (1) synthetic attacks data balancing, (2) LSTM feature extraction, (3) GRU classification. used drift identification. stores extracts long-term dependency data. beneficial In way, minimum false positive rate (FPR) obtained. Moreover, dropout regularization Adam optimizer are added tackling overfitting trapping model local minima, respectively. proposed TLGRU uses realistic EC profiles Chinese utility state grid corporation China analysis solve problem. From simulation results, it exhibited that 1% FPR, 97.96% precision, 91.56% accuracy, 91.68% area under curve obtained by model. outperforms existing terms ETD.

Electricity Theft Detection using Machine Learning
Non-technical losses (NTL) in electric power grids arise through electricity theft, broken electric meters or billing errors. They can harm the power supplier as well as the whole economy of a country through losses of up to 40% of the total power distribution. For NTL detection, researchers use artificial intelligence to analyse data. This work is about improving the extraction of more meaning...
متن کاملEntropy - based electricity theft detection in AMI network
Advanced metering infrastructure (AMI), one of the prime components of the smart grid, has many benefits like demand response and load management. Electricity theft, a key concern in AMI security since smart meters used in AMI are vulnerable to cyber attacks, causes millions of dollar in financial losses to utilities every year. In light of this problem, the authors propose an entropy-based ele...
متن کاملElectricity theft: a comparative analysis
Electricity theft can be in the form of fraud (meter tampering), stealing (illegal connections), billing irregularities, and unpaid bills. Estimates of the extent of electricity theft in a sample of 102 countries for 1980 and 2000 are undertaken. The evidence shows that theft is increasing in most regions of the world. The financial impacts of theft are reduced income from the sale of electrici...
