A phase-locked loop (PLL) is a nonlinear negative-feedback control system that
synchronizes its output in frequency as well as in phase with its input. PLLs are now widely …

The increasing penetration of distributed renewable energy sources (RES) requires
appropriate control techniques in order to remain interconnected and contribute in a proper …

The electric power system is witnessing a shift in the technology of generation. Conventional
thermal generation based on synchronous machines is gradually being replaced by power …

To improve the performance of phase-locked loops (PLLs) under adverse grid conditions,
incorporating different filtering techniques into their structures have been proposed in the …

Despite the wide acceptance and use of the conventional synchronous reference frame
phase-locked loop (SRF-PLL), no transfer function describing its actual input–output …

The phase, frequency, and amplitude of the fundamental-frequency positive-sequence
component of the grid voltage are crucial information in control of most grid-connected …

Phase-locked loop (PLL) technique is widely used for synchronization applications. A variety
of moving average filter (MAF)-based PLLs have been presented in recently published …

The presence of the dc component in the phase-locked loop (PLL) input results in
fundamental frequency oscillations in the phase and frequency estimated by the PLL. The …

With increasing the penetration of distributed and renewable sources into power grids, and
with increasing the use of power electronics-based devices, the dynamic behavior of large …

Islanded microgrids can enhance the resilience of power systems. Their stability is subject to
ongoing research. This work introduces a unique way of sensitivity analysis, parameter …
