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 …

Stable operation of LCL filtered grid-connected inverters can be achieved using active
damping. However, the stability can be threatened by non-ideal conditions such as delay in …

In this paper, a feedforward virtual inductance control strategy is developed for the stability of
voltage source inverters (VSIs) in weak grids. A weak grid is characterized by a low short …

SiC grid-tied inverters can reduce interface filter size and weight to reduce cost and achieve
fast dynamics, but pose control challenges, such as stability as well as large current …

With growing environmental concerns, the installation of distributed generation systems
forming microgrids in power systems has received much attention recently. This panacea …

This article analyzes the global stability of synchronous reference frame phase-locked loops
(SRF-PLLs) from a large signal viewpoint. First, a large-signal model of SRF-PLL is …

The nonignorable grid impedance is one of the characteristics of a weak grid. Meanwhile,
the filter inductance also fluctuates with temperature or aging factors. The resonant …

In single-phase grid-connected converters, unexpected perturbations and variations of
system parameters can deteriorate the performance of grid current and dc-link voltage …

A nonlinear optimization-based hybrid control architecture for grid-connected inverters is
presented in this article. The proposed control approach augments the existing inverter …
