Grid-tied inverters are widely used for interfacing renewable energy sources or storage
devices to low-voltage electrical power distribution systems. Lately, a number of different …

Due to the advantages of superior harmonics attenuation ability and reduced size, the LCL
filter has been widely adopted to interface between the inverter and the grid for improving …

When LCL-type converter is attached to weak grid, its current control and phase-locked loop
(PLL) will interact with each other, via the point of common coupling voltage. Unfortunately …

LCL resonance complicates the design of a current control loop and can even threaten its
stability. Extensive approaches have been proposed to deal with this resonance, among …

The phase-locked loop (PLL)-based grid-following inverters have been widely used as the
interface between renewable energy resources (eg, wind and solar power) and the utility …

An active power filter (APF) is a power electrical equipment that possesses the functions of
harmonic suppression and reactive power compensation in the power grid. Its performance …

This paper presents an adaptive multi-loop control scheme for inverters interlinking dc
voltage sources to single-phase, low-voltage ac grids. Control self-adaptation is particularly …

To suppress the effect of the point of common coupling (PCC) voltage on the grid current, the
unit PCC voltage feedforward scheme is commonly applied to the grid-connected inverters …

For the LCL-Filtered single-stage photovoltaic (PV) generators, the low-frequency power
oscillation (<; 50 Hz) occurs frequently when they are connected to the weak grid, whose …

This paper provides a new design procedure for robust state feedback current controllers
suitable for grid-tied inverters under wide grid impedance ranges. The proposed procedure …
