Performance enhancement of DSOGI-PLL with a simple approach in grid-connected applications

In the literature history, many enhanced phase locked loops (PLLs) have been presented to enhance the performance of synchronous reference frame-PLL (SRF-PLL) against the grid imbalances and disturbances. One of these methods is a dual second order generalized integrator-PLL (DSOGI-PLL), which provi...
