| Abstract: | This paper introduces the structure and control of single stage grid-connected photovoltaic system establishes photovoltaic array model and grid-connected photovoltaic model and simulates the output of grid-connected photovoltaic system with the change of illumination and temperature by photovoltaic array model.Simulation experiment shows that this single stage grid-connected photovoltaic system quickly and effectively tracks the maximum power point in photovoltaic array,accurately tracks the voltage phase as for grid-connected current control,assures the output current of inverter and the grid voltage of the same frequency and phase and guarantees the sinusoidal waveform with few ripples of current output. |
