Transient stability analysis in multi-terminal VSC-HVDC grids [PDF]
A novel approach to transient stability analysis in multi-terminal high voltage direct current (MTDC) grids is presented in this paper. A symmetrical three-phase fault in an ac grid connected to a rectifier terminal of the MTDC grid causes the power injected into the dc grid to decrease, which in turn leads to a lower dc voltage in the MTDC grid. If dc

Harmonic‐Amplitude Modulation Strategy for PtP‐VSC‐HVDC Links Providing Frequency Support
ABSTRACT This paper presents a communication‐free frequency support strategy for point‐to‐point voltage source converter high‐voltage direct‐current (PtP‐VSC‐HVDC) links. The proposed strategy is conceived as a harmonic‐amplitude modulation (HAM), where the frequency deviation experienced by one power system is described as an instantaneous bi ...

This paper introduces the waveform similarity index (WSI), which is an effective index to characterise the input current performance of harmonic injection matrix converter (HIMC). A closed‐loop control strategy is proposed to regulate the WSI difference through multi resonant controllers (RCs), which can fully suppress the effect of inaccurate harmonic
