A high performance grid synchronization method for renewable energy grid-connected applications

Aiming at the problem of insufficient harmonic suppression capability for distributed renewable energy grid-connected application equipments, an efficient grid synchronous phase-locked loop(PLL) which will suppress harmonics is proposed. Firstly, a novel high-order generalized integral (NHOGI) is pr...
