In this paper a sensor fault resilient control approach for electronically interfaced distributed energy resource (DER) in islanded (autonomous) microgrids is proposed. The proposed control strategy consists of sliding mode observer (SMO) and output feedback control law to ensure resiliency of DER units against erroneous measurements associated with sensor malfunctioning. The error in measurements results from malfunctioning of sensors are modelled as sensor faults in this paper. The SMO in the proposed approach estimates (reconstructs) sensor faults, and the reconstructed faults are used to devise fault tolerant control strategy. In order to demonstrate that the proposed control strategy is resilient to sensor malfunctioning, various simulation studies are carried out on single DER unit and multi DER units in an islanded microgrid.
