| Abstract: | Anti-islanding is the key problem for photovoltaic grid-connected power generation system.To overcome the shortcoming of the active frequency drift (AFD)method,a novel AFD islanding detection is proposed.The simulation model of the system is established,and the experimental results verify the good performance of the proposed method,which ensure the power quality recycling to the grid. |
