This paper proposes an optimizing design scheme of photovoltaic(PV) module according to the technical parameters of Grid-connected PV Power Plant. Statistics analysis was conducted on solar radiation data of chosen engineering area in the typical year with the assistance of RETScreen. Based on the analysis, the operation mode can obviously improve the PV module’s ability to use the sun light to design a dual-closed loops voltage space vector control strategy. The output current and its harmonics through inverter were simulated via Matlab/Simulink. The result indicates that current waveform has been significantly improved due to the above experiment. Moreover, the harmonics content fulfills the index requirements for current harmonic technique of grid-connected system, the photoelectric conversion efficiency has been further improved.
