Abstract

This study deals with the distributed power generation system (DPGS) connected to the grid, the major
issue is synchronization with grid. The phase-locked loop (PLL) is used for detecting the phase angle of the utility
voltage and locking the grid phase with the incoming power source. The synchronization of power electronic
converters with grid even in unbalanced and variable voltage/frequency situation is the main target of this paper. The
method Synchronous Reference Frame PLL (SRF-PLL) with PI-regulator gains calculated with the symmetrical
optimum method has been designed and simulations in SIMULINK have been made. Further another one method
double synchronous reference frame (DSRF-PLL) has been simulated and compared both techniques. For supporting
the research MATLAB simulation is utilized.
