Wind power generation is making an increasingly significant contribution to global electricity
production. The high penetration of wind power greatly affects the stability of modern power …

The wide adoption of a new type of electric trains results in multiple frequency-scale
instability problems, such as low-frequency oscillation (LFO), harmonic resonance, and …

The Grid-connected inverter (GCI) often operates in the weak grid with asymmetrical grid
impedance due to the unbalanced and single-phase loads. However, the time-periodic …

Recently, the converters controlled by droop controller with phase-locked loop were
observed in islanded ac microgrids. However, only the state-space-based approach was …

Power converters may lose synchronization with the remaining network when integrated in a
weak power grid. Such an instability phenomenon [known as grid-synchronization instability …

This article proposes a reduced-order small-signal closed-loop transfer function model
based on Jordan continued-fraction expansion to assess the dynamic characteristics of the …

A photovoltaic inverter (PVI) may enter operational instability region based on grid supply
conditions, such as the presence of voltage waveform distortions and high grid impedance …

The utilization of a large number of power electronic converters in the high-speed railway
system results in the low-frequency instability for the single-phase vehicle-grid system. In …

To address the growing dynamic issues in the power electronics-based power system, this
paper proposed an enhanced impedance-based stability analysis which can not only obtain …

Instability problem is an important issue for dc/dc conversion cascaded systems (Cascaded
system in short). Though most of the existing stabilization methods can stabilize the whole …
