The detection of false data injection attacks (FDIA) in new-type power systems urgently requires a balance between accuracy and real-time performance. To simultaneously improve detection precision and speed
this paper proposes a detection method based on a crown porcupine algorithm-optimized squeeze-and-excitation convolutional neural network (CPO-CNN-SE). Aiming at the problem that manual selection of hyperparameters for convolutional neural networks (CNN) often fails to achieve optimal configuration
the method utilizes the crown porcupine optimizer (CPO) to perform hyperparameter tuning
thereby enhancing the accuracy of the CNN detection model. Meanwhile
to meet the demand for faster FDIA detection
a squeeze-and-excitation (SE) attention mechanism is introduced to construct a hybrid learning model based on CNN-SE
which strengthens the CNN’s efficiency in representing spatial features of FDIA. Simulation results demonstrate that the proposed method can accurately and rapidly detect FDIA
providing important technical support for improving situational awareness and defense resilience of new-type power systems under complex cyberattacks.
