Study of DQ Rotating Frame Control for Single-Phase Photovoltaic Grid-Connected System

Abstract:

Nowadays solar photovoltaic energy has become an important alternative energy sources. This paper focuses on single-phase PV grid-connected system, a reference frame which used for three-phase inverter has been used in this single-phase grid-connected inverter. The in-quadrature signal is generated used T/4 transport delay technique. This single-phase grid-connected inverter uses space vector pulse width modulation(SVPWM) method. Finally, the 3KW small power single-phase photovoltaic inverter system model is built to verify the presented control strategy by using the Matlab/Simulink.
