Xiao, J. (author), Wang, L. (author), Qin, Z. (author), Bauer, P. (author)Communication-based distributed secondary control is deemed necessary to restore the state of islanding AC microgrids to set points. As its limited global information, the microgrids become vulnerable to cyber-attacks, which by falsifying the communicating singles, like the angular frequency, can disturb the power dispatch in the microgrids...journal article 2024
