%X this paper introduces a new approach for the analysis of the vulnerability of power systems based on a hybrid model: an efficient multi-objective optimization evolutionary approach (moea) and the use of deterministic network interdiction concepts (dnip). the paper analyzes the interaction between the power system£¿s component outages, due to external attacks or random failures and the system load shedding and considers that multiple prospective solutions could be selected, based on the preference of the decision-maker. a simple but powerful evolutionary algorithm can be used to address this multi-objective perspective. to illustrate the proposed approach, classical systems from literature are studied (ieee 30-bus and ieee-rbts) along with a simplified version of the italian power system. as presented, the approach can be used as an initial straightforward screening approach to identify severe system disturbances and, to reproduce and/or significantly improve upon the results presented in previous studies
