FLEP-SGS²: a Flexible and Low-cost Evaluation Platform for Smart Grid Systems Security

As digital emerging technologies are being widely integrated in the grid infrastructure, security incidents to these systems could have severe outcomes. In order to understand security vulnerabilities of both field devices and communication protocols used in the newly formed smart grid, testbed frameworks are developed to conduct vulnerability studies. To date, efforts in grid security to develop such testbeds have resulted in costly, non-modular, and proprietary-based environments. In this paper, we present FLEP-SGS ² : a flexible, scalable, multilayer, and low-cost platform to examine security scenarios in smart grid. Power systems simulation tools are integrated with open-source software and code running on Raspberry Pis. FLEP-SGS ² allows to investigate the performance of the testbed components and evaluate different cyber-attack scenarios on the power system operation while providing a user-friendly interface.
