According to the operating characteristics of a proton exchange membrane fuel cell (PEMFC) generation system, a PEMFC grid-connected control system model is developed and a virtual line-flux-linkage oriented vector control strategy (VFOC) based d-axis and a modified virtual flux-linkage observer are designed. The total harmonic distortion (THD) of grid-connected voltages and currents are measured by means of the criterion of IEEE Std1547-2003. The simulation results demonstrate that this PEMFC grid-connected control system can achieve unit power factor operation. Furthermore, the FFT analysis results testify that this grid-connected system can also decrease the total h
