Abstract: “As the current power grid system is upgrading to smart grid, it becomes more vulnerable to security attacks such as Denial-of-Service attacks. One type of such attacks is jamming attack. In this paper, we analyze the scenario in which the attacker can jam specific signal channels in order to change the electricity prices to create the opportunity for profit, and the defender protect a limited number of channels. Based on the electricity marketing model, we propose multi-act dynamic game between the attacker and the defender, in which both of them will take the optimal strategy to maximize their own profits. We construct the gaming process and discuss the prosperities of the outcome. Simulation results confirm the optimality and prosperities of the proposed scheme.”
