This paper presents a methodology in order to evaluate the security of electrical industrial systems considering security, quality, reliability and availability factors and the system response to sudden disturbances such as short circuit and harmonics.The models proposed using the probabilistic networks theory: Bayesian Networks and Generalized Stochastic Petri Nets. The obtained results allow the...
The augmented use of ICTs in power systems, and the dependency of the electrical infrastructure on this type of technology has created a new form of vulnerability: ICTs are exposed to denominated ldquocyberattacksrdquo. Due to this interaction as well as the importance of the electrical power systems, it is appropriate to assess the risk of how the power system security would be affected if it was...
This article presents a model to evaluate the power quality phenomenon denominated voltage sags by means of Bayesian networks. This model considers the main events that can be generated by the presence of voltage sags in the power industrial systems, especially on electronic and sensitive equipment. The relations of causality established between the main causes and the final effects consider both...
The electrical power system is a set of networks and assets offering a service of public nature essential for the society. Terrorist acts that can affect the power system are increasing. One of the causes is the growing activity of extremist groups from different nations around the world. This paper introduces a technique for ranking contingency resulting from terrorist acts that could represent larger...
