Dynamic simulation of simultaneous HVDC contingencies relevant for vulnerability assessment of the nordic power system
Solvang, Espen Hafstad; Sperstad, Iver Bakken; Jakobsen, Sigurd Hofsmo; Uhlen, Kjetil (Chapter, 2019)Large power-infeed of individual HVDC interconnectors may make the power system vulnerable to contingencies involving multiple HVDC interconnectors. This paper describes and demonstrates an approach to quantitative ... -
Dynamic Simulations of Simultaneous HVDC Contingencies in the Nordic Power System Considering System Integrity Protection Schemes
Solvang, Espen Hafstad (Master thesis, 2018)Individual HVDC links connecting the Nordic power system to other synchronous systems may carry gigawatts of power. For the transmission system operators, who must maintain power balance to operate the grid at 50.0 Hz, the ...
