N2 - Distributed secondary control schemes are widely adopted for distributed energy resources (DERs) to restore bus voltages and share output current/power in DC microgrids. However, when the control variables of the conventional distributed secondary control is attacked by false data injection (FDI) attacks, the control objectives cannot be achieved. More seriously, the stability of the entire DER system is threatened. To address this issue, a distributed linear state observer (DLSO)-based distributed secondary control is presented in this digest. The DLSO detects the attack signals based on local and neighboring measurements. The estimated attack-signals in the DLSO are further compensated by the control variables of the distributed secondary control to eliminate the negative impact from the cyber-attacks. Both simulation and experimental results have validated the effectiveness of the proposed control for both bus voltage regulations and output current/power sharing.
