For stability processes that are difficult to perform in real time, security evaluation approaches for current SG devices may therefore require extensive historical domain training. Given that predictions are instantaneous, machine learning (ML) can be used to predict DSA. To classify and predict the time margin and transient energy margin (TEM) for a specific fault position and operating condition, input features, reactive power outputs, SG device transient energy function (TEF) terms, and fault location are used. False data injection (FDI) attacks are analyzed to predict the vulnerability using the developed Stacked Autoencoder (SAE) with ML models. In particular, the hybrid voting machine classifier (VMC) values are modified, and the data features are used to identify attack targets. The proposed technique is more effective because it uses ML models to develop an instance-based DSA method that identifies high-importance features to inform effective predictive countermeasures against FDI attacks in the SG system. The proposed algorithm’s viability is confirmed using test power systems on the real-time 128-feature IEEE 3-bus dataset and our developed Industrial Internet of Things (IIoT) dataset, namely the UKMNCT_IIoT_FDIA dataset (Published in Data in Brief; dataset available at: https://zenodo.org/records/14864902).
