In standard implementations of distributed secondary control for DC\nMicroGrids (MGs), the exchange of local measurements among neighboring control\nagents is enabled via off-the-shelf wireless solutions, such as IEEE 802.11.\nHowever, Denial of Service (DoS) attacks on the wireless interface through\njamming prevents the secondary control system from performing its main tasks,\nwhich might compromise the stability of the MG. In this paper, we propose\nnovel, robust and secure secondary control reconfiguration strategy, tailored\nto counteract DoS attacks. Specifically, upon detecting the impairment of the\nwireless interface, the jammed secondary control agent notifies its peers via a\nsecure, low-rate powerline channel based on Power Talk communication. This\ntriggers reconfiguration of the wireless communication graph through primary\ncontrol mode switching, where the jammed agents leave the secondary control by\nswitching to current source mode, and are replaced by nonjammed current sources\nthat switch to voltage source mode and join the secondary control. The strategy\nfits within the software-defined networking framework, where the network\ncontrol is split from the data plane using reliable and secure side power talk\ncommunication channel, created via software modification of the MG primary\ncontrol loops. The simulation results illustrate the feasibility of the\nsolution and prove that the MG resilience and performance can be indeed\nimproved via software-defined networking approaches.\n
