Abstract

In PV microgrid control system, the delay and filter inductance value change will influence the response speed, stability and grid-connected current distortion rate of system. Therefore, this article proposes a power feedforward robust prediction dead-beat grid-connected control method. The system’s response speed is sped up by introducing power feedforward. The robust prediction dead-beat control method is proposed to be used on grid-connected control to strengthen robustness of system and reduce distortion of grid-connected current caused by control delay and inductance value deviation. It also analyzes Z-domain dead-beat control model and discusses influences of delay and inductance value on system stability. This article gives the design method of robust prediction dead-beat control and performs stability analysis according to transfer function within Z-domain, determines selection scope of control parameters. The simulation and experiment results prove the effectiveness of the proposed control method.
