Abstract

The model and simulation of three-phase Two-level Grid-connected Photovoltaic System are established. According to the equivalent circuit and mathematical model of the PV cell, the general simulation model of photovoltaic array is established. Regulating duty ratio in Boost circuit to realize the maximum power point tracing with method of high-precision incremental conductance. Model of photovoltaic inverter is established based on power decoupling vector control strategy. SVPWM modulation improves the utilization ratio of voltage in DC side. Finally, the simulation of three-phase two-level grid-connected photovoltaic system is conducted in MATLAB. The result shows that the system can rapidly and accurately track maximum power point and the output of current keep in the same frequency and phase, which can be connected to power grid flexibly.
