Abstract

This paper proposed a method for controlling the active power of a single-phase grid-connected photovoltaic(PV) system by the quasi-Z-source inverter (QZSI). The MPPT of PV array is achieved by adjusting a shoot-through time of QZSI. The PI+R controller is used for reducing the steady-state error of the grid current. The simulation studies are carried out to verify the performances of proposed system.
