Abstract

With the high penetration of renewable energy sources in power systems, DC microgrid clusters are widely installed and employed that can interface several types of renewable energy sources to different types of loads. However, being highly dependent on communication networks, DC microgrids are exposed to cyber-attacks. Therefore, in this paper, a resilient cooperative control method is proposed for DC microgrid cluster systems, that is able to achieve both the voltage regulation and power sharing in the presence of cyber-attacks. Firstly, a comprehensive microgrid cluster model is developed taking the grid forming converters, grid feeding converters, loads and line impedances into account. Based on the Lyapunov-based stability analysis, a design guideline for controller that depends only on parameters of the local microgrid is then presented. Next, steady state analysis is carried out showing that the controller is capable of eliminating the impact of cyber-attacks on the microgrid. Finally, the resilience performances of the provided control scheme are validated by experimental results.
