Experimental results show that, through the proposed approach, neural networks can be used to learn parameters underlaying system behaviour, and their output processed to detecting anomalies due to hijacking of measures, changes in the power network topology (i.e. transmission lines breaking) and unexpected power demand trend. %R 10.1007/978-3-540-30132-5_168 %U http://mclab.di.uniroma1.it/publications/papers/papers/Martinelli2004.pdf %U https://doi.org/10.1007/978-3-540-30132-5_168 %P 1242-1248
