(English Abstract)
Due to the charging system for electricity in which the amount of money charged varies depending on the purpose it is used for, as laid out by the contract between the electricity provider and the consumer, any losses caused by contract violation can be greatly increased. Recently, with the expansion of the Advanced Metering Infrastructure (AMI), it has become possible to collect the electricity usage information of consumers in real time through smart meters. However, studies into the detection of violations, including contract type violations, still have difficulties caused by data imbalances due to a lack of collected violation data. In this paper, we propose a method to detect contract type violations by modelling normal usage patterns based on normal consumers¡¯ usage data according to specific contract type: from this base we apply an abnormal pattern detection method to the AMI smart meter data stream of consumers with a particular contract type. In an experiment simulating contract violations using power usage data of about 300 people collected from smart meters over a 3 years 7 months period, the proposed method obtained an f1 value of 0.83 and a detection delay of, on average, 6 days after violation occurred. This shows that the proposed method can be effectively used for detecting contract violation in real situations.
