Accurate and Efficient Harmonic Estimation for LCC-HVDC Systems
EnergiesModern grids’ dual-high characteristics elevate the role of wideband impedance measurement in operational risk assessment. In thyristor-based line-commutated converter-based high-voltage direct-current (LCC-HVDC) systems, where severe waveform distortion and high harmonic content prevail, nonintrusive wideband techniques rely on precise spectral ...

Increased Capacity Using VSC‐HVDC Emergency Control in Voltage Stability‐Constrained Systems
IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This paper proposes a VSC‐HVDC emergency power control strategy for increasing transmission capacity in voltage stability‐constrained systems. The method derives the active–reactive power allocation that maximises loadability when converter limits are reached, and implements it using either PMU‐based wide‐area angle measurements or local fallback ...
