摘要: Single-stage grid-connected photovoltaic (PV) systems have advantages such as simple topology, high efficiency, etc. However, since all the control objectives maximum power point tracking (MPPT), synchronization with utility voltage, and harmonics reduction for output current need to be considered simultaneously, complexity of scheme is much increased. This paper presents implementation a single-stage three-phase PV system. In addition realize aforementioned objectives, proposed can also remarkably improve stability MPPT method modified incremental conductance method. The reactive compensation local load realized, so alleviate grid burden. A DSP employed implement controller unit. Simulation experimental results show efficiency this
