N2 - Wide-Area Load Shedding (WALS) protection schemes are the schemes used in power system to perform a load shedding after a large disturbance in the power system. These schemes are used to avoid power system cascading if all other remedial means fail to mitigate against a large disturbance. Hence, any small mistake in the operation of WALS protection schemes may result in huge damage in the power system i.e., blackouts, component damage, service disruption, etc. Since WALS protection schemes are centralized schemes that use communication system, they are vulnerable against cyber attacks. This paper shows the effects of False Data Injection (FDI) cyber attacks on the WALS protection schemes. To validate the problem formulation, the IEEE 39 bus New England system is simulated under FDI attacks using the AC power flow. The results show that the attacker can alter the load shedding distribution or location, and as result forces the control center operator to make an unintended load shedding decision and deviate from the optimal course of action.
