A household wind generation system connected with the grid are advanced in this paper, in which a diode rectifier, a boost DC/DC converter and a single-phase inverter paralleled with the grid are utilized, and a grid-connected operation mode without power injection is adopted. A double-loop control method with a current loop and a voltage loop is applied to the inverter so that the inverter feed no power into the grid. Islanding prevention is simply and effectively realized by the control strategy. The effectiveness of the control strategy is verified by simulation under different operating conditions and by parallel operation experiments for the single-phase inverter.
