North of Norway has extremely good conditions for wind power generation. As the existing main

grid will not be able to integrate all the wind parks, the alternative to build a new corridor with

multi-terminal HVDC Light North of Norway to Middle of Norway, is under study.

HVDC Light is more and more concerned recently to improve power system stability due to its

supreme controllability. The thesis will be directed towards investigating the possible problems to

be encountered in an HVDC Light installation. A platform for the control of HVDC Light based on

the vector control principle will be first established. With a good understanding of this control

platform, the model will then be tested under several circuit conditions, to test the capability and

robustness of the controller to handle these situations.-North of Norway has extremely good conditions for wind power generation. As the existing main
