Distributed Generators (DG) systems based on Renewable Energy Sources (RES) such as
hydro, wind, and solar power plants have been spread widely due to their lower cost and the …

Renewable Energy Sources (RES) are widely used worldwide due to their positive effect on
the environment, being sustainable, low cost, and controllable. The power generated from …

DC-offset in the input of the phase-locked loop (PLL) is an emerging problem that causes
oscillations in the estimated fundamental grid phase, frequency, and voltage amplitude. The …

With the increasing penetration of renewable energy, a weak grid with declining inertia and
distorted voltage conditions becomes a significant problem for wind and solar energy …

Fast and accurate monitoring of the phase, amplitude, and frequency of the grid voltage is
essential for single-phase grid-connected converters. The presence of DC offset in the grid …

Due to the increasing penetration of single-phase distributed generations into the utility grid
the need of an improved and efficient controller to control the distributed power generating …

In power distribution networks, the fundamental positive-sequence component detection of
the utility voltage is required to synchronize the control reference signals of power …

This paper presents a comparative study of two grid synchronization techniques,
synchronous reference frame phase-locked loop (SRF-PLL) and double synchronous …

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

The phase-locked loop (PLL) is an essential synchronization technique to ensure stable
operation and control of grid-connected converters. Nevertheless, under actual conditions …
