For this purpose, this paper proposes a new methodology that evaluates the substitution of the power flow technique by the geodesic vulnerability index to identify critical nodes in power grids. Both methods are applied comparatively to demonstrate the scope of the proposed approach. The applicability of the methodology is illustrated using the IEEE 118-bus test system as a case study. To identify the critical components, a node is initially disconnected, and the performance of the resulting topology is evaluated in the face of simulations for multiple cascading faults. Cascading events are simulated by randomly removing assets on a system that continually changes its structure with the elimination of each component. Thus, the classification of the critical nodes is determined by evaluating the resulting performance of 118 different topologies and calculating the damage area for each of the disintegration curves of cascading failures. In summary, the feasibility and suitability of complex network theory are justified to identify critical nodes in power systems. info:eu-repo/grantAgreement/ES/MINECO/ENE2016-77172-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 4.469 2021 ENGINEERING, ELECTRICAL & ELECTRONIC 78 / 274 = 0.285 2021 Q2 T1 1.438 2021 Renewable Energy, Sustainability and the Environment 2021 Q1 Energy Engineering and Power Technology 2021 Q1 8.7 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Garcia-Paricio, Eduardo Universidad de Zaragoza (orcid)0000-0003-2457-0422 Ruiz, Hector F.
