...his study investigates the techno-economic potential of offshore power generation from natural gas with carbon capture and storage to reduce the climate impact of mainland electricity and the offshore oil and gas industry. This potential is assessed through techno-economic assessments over two relev...

In the increasingly interconnected and integrated European power system, transmission system operators need to consider new kinds of risk associated with the interconnection to neighbouring systems. For the Nordic power system, there is now more than 8 GW of HVDC interconnector capacity connecting t...

Expansion of offshore wind power and the use of high voltage direct current (HVdc) technologies in power transmission are modifying the power system dynamics making them more sensitive to power disturbances. Thus, in order to ensure a power system secure and stable operation, transmission system ope...

Grid codes are technical specifications that define the requirements for any facility connected to electricity grids. Wind power plants are increasingly facing system stability support requirements similar to conventional power stations, which is to some extent unavoidable, as the share of wind powe...

Investment model cost parameters for VSC HVDC transmission infrastructure continue to be associated with high uncertainty and their validity remains a crucial challenge. Thus, it is the key objective of this analysis to identify a new cost parameter set providing better investment cost estimates tha...

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 ...
