Abstract :
To guarantee a smooth transition from islanding mode to grid-connected mode, synchronization is the first issue to be considered. This paper puts forward a new synchronizing strategy based on voltage-controlled inverter. It can easily and accurately make the voltage frequency and phase of the distributed generation system track the main grid even if it varies. At the same time, there is a very small voltage instantaneous impact on the output voltage and the current.
