Power system security assessment is a major issue among the fundamental functions needed for the proper power systems operation. In order to perform the security evaluation, the contingency analysis is a key component. However, the dynamic evolution of power systems during the past decades led to the necessity of novel techniques to facilitate this task. In this paper, power systems security is defined based on the N-l contingency analysis. An artificial neural network approach is proposed to ensure the fast evaluation of power systems security. In this regard, the IEEE 14 bus transmission system is used to verify the performance of the proposed model, the results showing high efficiency subject to multiple evaluation metrics.

The lack of strong cyber-physical modeling capabilities presents many challenges across the design, development, verification, and maintenance phases of a system [7]. Novel techniques for modeling the cyber-grid components, along with analysis and verification techniques, are imperative to the deployment of a resilient and robust power grid. Several works address False Data Injection (FDI) attacks to the power grid. However, most of them suffer from the lack of a model to investigate the effects of attacks. This paper proposed a cyber-physical model using Architecture Analysis & Design Language (AADL) [15] and power system information models to address different attacks in power systems.
