A phase locked loop (PLL) generates the frequency and phase angle of the grid that can be used to synchronize a grid connected converter. The tutorial describes with examples the concept of a PLL with simulation examples. The zip file available here contains the report (pll_tutorial.pdf), simulation files and a README document with information about the contents and the software Python Power Electronics.
