For single-phase grid-connected inverters, the second-order generalized integrator-based
phase-locked loop (SOGI-PLL) is widely used for good harmonics attenuation and frequency …

In recent decades, Renewable Energy (RE) generation and penetration to the grid has
grown tremendously. The REs are intermittent in nature and connected to the grid through …

Control design of advanced grid synchronization systems is complex as they are often
adaptive nonlinear feedback systems with one or more filtering networks and feedback …

The multiple second-order generalized integrator (MSOGI), which is composed of parallel
second-order generalized integrators (SOGI), is widely used in grid synchronization and …

This work presents an enhanced second-order generalized integrator (ESOGI) based

Aiming at the accuracy deterioration of the synchronous reference frame phase-locked loop
(SRF-PLL) caused by the non-ideal grid conditions and the limitation of phase-locked loop …

Grid forming (GFM) inverter interfaced energy storage system can offer frequency support for
islanded microgrids (IMGs), and the frequency response relies on the GFM inverter's power …

Grid-connected converters require grid frequency and phase information for controlling the
power injections into the grid. This information is achieved by a phase-locked loop (PLL) or …
