Distributed MPC-Based Constant Voltage Control for DC Microgrids Under DoS Attacks

This paper investigates the voltage control problem of DC microgrids under asynchronous denial-of-service (DoS) attacks. Considering the maximum continuous DoS attack on the communication channel between the subsystems, a prediction-based data security transmission strategy is proposed to compensate for the data loss caused by asynchronous DoS attacks. Based on this, a secure communication-driven distributed predictive controller is further constructed to ensure the stability of bus voltage in DC microgrids under DoS attack. It is worth emphasizing that by combining the secure transmission strategy with the distributed predictive controller, this study ensures the stable operation of the DC microgrid even under asynchronous DoS attacks. Finally, the effectiveness of the proposed security control method is validated through a series of simulations.
