The present invention discloses a method for detecting abnormal
electricity consumption behavior applicable to a
new energy distribution network. Based on historical data of user stations,
feature extraction is performed to obtain a sample set of a network for screening suspicious
electricity consumption behavior. Three-layer
deep learning screening networks are respectively constructed according to the
coupling degree of data in a
training set, and training of the suspicious behavior screening network is completed based on the sample set. The historical abnormal data is used as a sample set for
false alarm identification, and an abnormal
false alarm identification model is established. Data in an
electricity collection system is input into a suspicious behavior screening network after
feature extraction, and when the output abnormal state value exceeds a threshold, the user data is transmitted to an abnormal
false alarm identification model. The abnormal false alarm identification model identifies whether there is an abnormal false alarm in the suspicious electricity consumption behavior of the user according to the characteristics of the electricity consumption data, and if so, the user is included in a monitoring
list. The method is executed again for users in the monitoring
list, and if the output abnormal state value still exceeds the threshold, it is determined that the user has abnormal electricity consumption behavior.
