As one of the most sophisticated attacks against power grids, coordinated cyber-physical attacks (CCPAs) damage the power grid's physical infrastructure and use a simultaneous cyber attack to mask its effect.

By manipulating tens of thousands of internet-of-things (IoT) enabled high-wattage electrical appliances (e. g., WiFi-controlled air-conditioners), large-scale load-altering attacks (LAAs) can cause severe disruptions to power grid operations.

Our results show that the SINDy algorithm outperforms the PINN and UKF algorithms in being able to accurately estimate the power grid parameters over a wide range of system parameters (including high and low inertia systems).

To overcome this drawback, we propose a DNN-based OPF predictor that is trained using a meta-learning (MTL) approach.
