Resilient Collaborative Distributed Energy Management System Framework for Cyber-Physical DC Microgrids

This article investigates the resilience of the consensus-based distributed economic dispatch (ED) in cyberphysical DC microgrid energy management system (EMS). A holistic framework, called resilient collaborative distributed EMS (R-CoDEMS), is proposed to model the system dynamics, adversaries, and the cybersecurity of the consensus-based distributed ED. Under the R-CoDEMS framework, a reputation-based distributed attack detection and mitigation algorithm is also proposed to improve the system's resilience against typical non-colluding and colluding false data injection attacks. The effectiveness and scalability of the proposed R-CoDEMS countermeasure is evaluated on a typical microgrid system and large-scale networks via numerical simulations.
