In this study, the effect of attacks on networked systems is studied and a new security index to analyse the impact of such attacks usingH 2 norms of attacks to target and monitoring outputs is proposed. In addition, optimisation problems for selecting inputs or outputs that point to attacks with maximum impact and least detectability are posed, and subsequently solved. To demonstrate the applicability of the analysis methods proposed in this study, the IEEE 9‐bus and 50‐generator 145‐bus systems are considered as test cases.
