Based on Feed-Forward Photovoltaic Grid Converter Control Strategy

Abstract:

In photovoltaic grid-connected system, the method of adding voltage feed-forward to improve the shape of grid-connected current wave is presented, the reason for the introduction of the net voltage feed-forward decreasing the phasic difference between grid-connected current and net voltage and reducing the THD of grid-connected current is analyzed. It is confirmed that the net voltage feed-forward compensation can improve grid-connected current availably by the results of simulations and experiments, keep the current frequency and phase synchronous to the grid.
