Smart Grid Security Applied to the Brazilian Scenario: A Visual Approach

Many countries are experiencing a transformation from the traditional generation power system into a smart grid which incorporates communication and data processing technologies. New services become possible and are important to improve the system operation, but there is a large increase in data gathering. This new paradigm increases the complexity of the network and brings new security issues. This article simplifies the understanding of security in power networks by surveying one hundred and eight recent studies in smart grid security, mapping graphically the type of risk they represent to their location in the smart grid, organizing them by the lifecycle of smart grid data as proposed by 1, and comparing the ideal case to the current Brazilian scenario.
