In the photovoltaic micro-grid control system, delay and filter inductance change can influence system response speed, stability and grid-connected current distortion rate. Therefore, a power feed-forward dead-beat grid-connection control method for robustness prediction is proposed in this paper. The power feed-forward control is introduced therein to accelerate the system response speed, and the dead-beat control method for robustness prediction is proposed for the grid-connected current control in order to strengthen system robustness and reduce the grid-connected current distortion caused by control delay and inductance deviation. Specifically, Z-domain dead-beat control model with delay link is analyzed in this paper in order to discuss the influence of delay and inductance on system stability and accordingly provide the dead-beat control design method for robustness prediction as well as analyze the stability thereof according to the transfer function in Z-domain, thus to determine the control parameter scope. Moreover, the simulation experiment results have verified the effectiveness of the proposed control method.
