N2 - This paper proposes a power flow control strategy (PFCS) for a decentralized DC microgrid (DCMG) system using transition operations based on the DC-link voltage (DCV) observer value to achieve both the voltage and power regulations even under DCV sensor faults. The transition operation modes are employed to transmit the information of the DCMG system to other power agents without any digital communication links while the steady-state operation modes are used to ensure the DCV regulation to the nominal value. Moreover, to maintain the system stabilization even under DCV sensor faults, a voltage sensor fault identification method is introduced for each power agent in the decentralized DCMG by using the estimated DCV value. When a DCV sensor fault occurs in a power agent, its operation is adjusted to the proper control mode to ensure the DCMG system stabilization. Several simulations are carried out with the PSIM software to verify the reliability of the proposed PFCS.
