Cooperative Jamming Attack Strategy against Power Balance of Wireless Smart Grid Networks

Wireless based smart grid networks are widely applied due to its features of efficiency and agility to the power system. However, it is also vulnerable to malicious attacks via the communication channels, which has a great impact on stability of the whole power system. In this paper, a cooperative jamming attack strategy is proposed, in which a team of mobile attackers is tasked to jam the power price signals sent by the control center to power users, and halt jamming operation when the true price value monitored by attackers has been varied noticeably. Based on a dynamic coverage control scheme, attackers optimally coordinate their motion and continually disrupt wireless communication channels between power users and the control center during each jamming operation period. It ensures that the instantaneous imbalance of generated power and consumed power at the control center is gradually up to a maximum level when the true price is updated by local unit of each power user. The effect of such an attack is also discussed analytically. Simulation results are provided to validate the effectiveness of the proposed method.
