Distributed Primary Frequency Control through Multi-Terminal HVDC Transmission Systems [PDF]
, 2015 This paper presents a decentralized controller for sharing primary AC frequency control reserves through a multi-terminal HVDC grid. By using Lyapunov arguments, the proposed controller is shown to stabilize the equilibrium of the closed-loop system ...

Economy Analysis of Flexible LCC-HVDC Systems with Controllable Capacitors
CSEE Journal of Power and Energy Systems, 2022 Commutation failure (CF) is a frequent dynamic event at inverter of LCC-HVDC systems caused by AC side faults which can lead to inverter blocking, interruption of active power transfer, and even system blackout. To eliminate CFs and improve system performance, new Flexible LCC-HVDC topologies have been proposed in previous research but with limited ...

Harmonic Analysis of Transmission Scheme for Offshore Wind Farms Based on Diode Rectifier Unit
Engineering Reports, Volume 7, Issue 10, October 2025.This paper builds a general mathematical for the multiple rectifier circuit used in DRU, which is based on the 12‐pulse and 24‐pulse rectifier circuits, and analyzes the harmonics of DRU using different rectifier circuits before and after the installation of AC filters by an offshore wind farm integration project. ABSTRACT The diode rectifier unit (DRU)

Design of cooling structure improvement of hybrid commutated converter valve
High Voltage, Volume 10, Issue 3, Page 570-580, June 2025.Abstract This paper presents a thermal management framework for 120 kV hybrid commutated converter (HCC) valves, addressing critical cooling challenges in multi‐hundred‐MW power conversion systems. Power loss calculations under rated (1.0 p.u.) and overload (1.2 p.u.) conditions demonstrate that HCC valves achieve comparable loss levels to line ...
