The dc distribution power system has drawn widespread attention and rapidly developed in
recent years; however, its stability issue is one of the urgent challenges, requiring much …

The high penetration of renewables has sparked new oscillatory concerns in hybrid AC/DC
grids. Knowledge of the oscillation regarding its source and propagation mechanism, is …

Two individually stable converters are well-known preconditions for discussing the stability
of a two-stage cascaded system. However, for a multistage cascaded system, the …

This two-part paper presents a general method to model three-phase ac-dc converters in the
frequency domain for power system stability studies. In the developed approach, an ac-dc …

Growing concerns with the harmonic oscillation phenomenon of multiterminal DC (MTDC)
systems calls for appropriate harmonic stability analysis methods. However, the …

Virtual synchronous machine (VSM) based high voltage dc systems enhance the inertia of
the power system. However, the dynamic interactions between the VSM-based rectifier …

This paper is mainly focused on the stability-related issues of a grid-tied interlinking
converter system. First, hybrid AC/DC admittance characteristics of an interlinking converter …

The impedance-based criteria are well known to assess the stability of DC systems by
impedance measurement method. However, these criteria apply to the DC systems with the …

The hybrid AC/DC admittance of interlinking converters operating under AC voltage control
mode may contain right half-plane (RHP) pole (s), and thus, the existing harmonic stability …

For grid-connected converters operating under nonunity power factor, their admittances
become off-diagonal due to emerging of the coupling admittances. Consequently, the grid …
