| Abstract: | In this paper, Denial-of-Service (DoS) attacks on a microgrid (MG), especially on service-provider-edge routers in the MG, are considered and analysed. To increase the tolerance of the MG for DoS attacks with decreased computing time, we present consensus-based secondary frequency controllers with dynamic P-f droop controllers. Then, with the consideration of the impact on these controllers caused by DoS attacks, a state-space model of the MG is established based on which the stability analysis is derived. Finally, the effectiveness of the method is verified by simulation and experimental results. |
