Traditional thermal-based microgrids are transforming towards distributed renewable energy sources (DRESs) dominated microgrids, aiming at promoting sustainable environment and economy. This work thus incorporates two popular DRESs (i.e., wind turbines and plug-in electric vehicles (PEVs)) in the thermal-based power plants. Considering the inevitable sensor failures caused by hostile outdoor environment and the communication failures caused by resource constraints, this paper proposes a novel handling method to intermittent feedback in load frequency control (LFC) for microgrids. Furthermore, to deal with the fluctuations of power outputs from DRESs, this paper incorporates the robust performance index into the control law derivation. By taking into account such intermittent feedback and robust performance index, the operation of microgrid system can better realize resiliency enhancement. Validation results demonstrate the feasibility of this novel handling method under different degree of intermittent feedback.
