The contribution of solar photovoltaic (PV) in the electrical power sector is increasing
expeditiously. Recent interest in the integration of solar PV into the grid raises concerns …

Synchronization is the key part to ensure the high performance of grid-connected systems.
Phase-locked loop (PLL) is one of the most popular synchronizations due to its simple …

The scope of this work is to find the best approach to control advanced inverters used to
connect electric vehicles to the grid. Phase-locked Loop (PLL) is a grid voltage phase …

This paper presents an active islanding detection method which has zero non-detection
zone. This method is the advanced version of the conventional slip mode frequency shift …

Phase synchronization and frequency tracking are essential part of control unit design for
the grid-tie power converter of the efficient energy conversion system. A robust but …

It is well known that network analyzers perform reliable estimations of the Total Harmonic
Distortion (THD). A distorted signal is actually decomposed in real time into its harmonic …

This paper discusses the design, modelling and analysis of a single-phase grid-tied
photovoltaic (PV) system feeding a variety of loads. Normally, the phase-locked loop (PLL) …

This paper presents the digital implementation of an adaptive notch filter (ANF) for the
application of utility grid synchronization. Due to the nonlinear structure of the ANF, the …
