This paper investigates the harmonic interactions of current controllers in multiparalleled
grid-connected inverters. Potential harmonic instability phenomenon, which features …

Three-phase inverter-based multibus ac power systems could suffer from the harmonic
instability issue. The existing impedance-based stability analysis method using the Nyquist …

Stability analysis of power-converter-based ac systems poses serious challenges not only
because of the nonlinear nature of power converters, but also because linearization is not …

Frequency-domain stability criteria are developed for converter-based power systems with
any number of converters. The converters may be grid following or grid forming, and the grid …

Paralleled inverters with asynchronous carriers are increasingly emerging into renewable
power plants and other power-electronic-based power systems. The sideband harmonics …

Small-signal stability is an important concern in three-phase inverter-based ac power
systems. The impedance-based approach based on the generalized Nyquist stability …

The small time constants of power electronics devices lead to dynamic couplings with the
electromagnetic transients of power networks, and thus complicate the modeling and …

The aim of this paper is to analyze the power quality of a low-voltage distribution or a stand-
alone network with different grid connected power converter topologies. Passive harmonic …
