a distribution network false data injection attack detection method based on attention mechanism and bidirectional long short-term memory network is proposed. Initially
the measurement data gathered by power system is broken down through variational mode decomposition
introducing the idea of signal energy to identify the most suitable mode number for variational mode decomposition. Subsequently
a small disturbance attack vector is constructed. Reconstruction of the measurement data using the Pearson correlation coefficient to filter out the high-frequency noise in the measurement data. Ultimately
a bidirectional long short-term memory network detection model based on the attention mechanism is designed. The reconstructed time series measurement data and attack vector are used as training set input and verified using the test set. The proposed method is verified by comparative experiments. The results show that this method can effectively improve the detection accuracy of false data injection attacks in distribution networks. This helps enhance the ability of the distribution network to resist attacks and ensures the safe operation of the power system.
