| Abstract: | The grid-connected inverters control technology becomes a research hotspot,because the inverter is an important equipment,which connects the photovoltaic grid-connected system and the grid.At first,the principle of the d-q coordinate transformation and passivity are introduced,and then a grid-connected current control strategy based on passivity and d-q coordinate transformation is designed.Finally,the modeling and the simulation of the system based on MATLAB/SIMULINK environment are presented.The experimental result verifies that the output wave of gird-connected current is good,and it has the same frequency and phase as utility grid. |
