Impact of present and future HVDC links on the nordic power grid

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1475684

This article presents preliminary results from ongoing work on establishing a simulation model for R&D activities on the impact of the increasing number of HVDC links in the Nordic power grid. The total HVDC power capacity will be 13100 MW (excluding some smaller systems) by 2021. This study add...

Review of investment model cost parameters for VSC HVDC transmission infrastructure

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1481167

Cost parameters for VSC HVDC transmission infrastructure have been gathered from an extensive collection of techno-economic sources. These cost parameter sets have been converted to a common format, based on a linear investment cost model depending on the branch length and the power rating of cable ...

Optimal Operation Voltage for Maximal Power Transfer Capability on Very Long HVAC Cables

http://www.sintef.no/en/publications/publication/?pubid=CRIStin+1392510

An analytical approach towards the operation of very long HVAC cables has been developed. The main physical phenomena have been expressed with simplified analytical equations. A comparison with numerical simulations has shown acceptable accuracy. A set of long distance cable parameters has been intr...
