Resumo

The use of IEDs in substations have brought a great improvement in terms of speed, costs, maintenance, and reliability. In this context, the use of IEC 61850 standard appears as one of the main recommendations for substation automation in smart grids that perform the electrical network control and protection in a digitally. Nevertheless, this improvement may cause several security issues. Therefore, security threats in substation networks must be detect in order to improving cyber security solutions. Thereat, we improve GEEESE generator in order to allow interaction with operator through a graphical interface. GEESE 2.0 allows a cyber security threat validation. We deployment a substation local networks and use GEESE 2.0 to perform an attack. After we analyze the impact of an attack in a protection scheme of a substation .
