| Abstract: | This paper researches a new grid synchronization method for grid-connected power converters under unbalanced and distorted grid conditions. This method is called MSOGI-FLL. A harmonic decoupling network is consisted of multiple second-order generalized integrators and a frequency-locked loop, which can detect positive and negative component by filtering harmonic components and makes the system frequency adaptive. MSOGI-FLL is analyzed and compared with DSOGI-FLL. Finally, this paper uses MATLAB simulation software to test these methods, the simulation results validate the performance of this method. |
