Segurança Cibernética em Microrredes: Estado de Arte e Desafios

Abstract

The evolution that the world's electric grids have gone through in recent years (becoming intelligent) brings several advantages, such as reduced electric losses, optimization of their operation, greater integration of distributed generations, among others. However, when becoming intelligent networks, electrical networks become extremely dependent on information and communication systems with higher resilient and trustworthy standards. This feature makes the grid vulnerable to cyber-attacks of the most varied types. This bibliographical review proposes to expose some of these possible threats to smart grids, with a particular focus on the so-called microgrids, as well as their characteristics, defense mechanisms and attack detection and possible failure recovery modes.
