Power delivery in multiterminal VSC-HVDC transmission system for offshore wind power applications [PDF]

2010 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT Europe), 2010
This paper deals with one of the challenges in the field of offshore wind power systems: power transmission among the wind farms and the land when there is more than one AC grid to be considered. This case is known in the literature as multiterminal connection. The proposed studies are going to present three strategies in order

Impedance-compensated grid synchronisation for extending the stability range of weak grids with voltage source converters [PDF]

, 2016
This paper demonstrates how the range of stable power transfer in weak grids with voltage source converters (VSCs) can be extended by modifying the grid synchronisation mechanism of a conventional synchronous reference frame phase locked loop (PLL).

Improved DC Properties of Polypropylene HVDC Cable Insulation by Grafting and Blending Combined Modification

High Voltage, EarlyView.
ABSTRACT In order to meet the needs of mechanical properties of cable insulation, polypropylene (PP) needs to be blended with low modulus materials to achieve toughening and softening. However, the compatibility between two or more resins can significantly affect the electrical properties of the composites.

A Novel AC/DC Power Flow: HVDC-LCC/VSC Inclusion Into the PFPD Bus Admittance Matrix

IEEE Access, 2022
In this paper, the matrix algorithm PFPD is generalized in order to compute the power flow solution of real and large AC/DC transmission networks. In particular, it is demonstrated that the HVDC-VSC/LCC links can be seen from the AC power systems as PV ...
