This research proposes a methodology for mapping operational zones of transmission systems based on voltage source converter high voltage direct current technology (VSC-HVDC) linking offshore ports to onshore power grid. Various operational conditions are investigated using the simulation software PECAD in order to evaluate the feasibility of application of VSC-HVDC technology on offshore ports whereas supporting three economic activities: transshipment, subsea mining and power generation. The electrical power source considered in this research is based on nuclear energy or driven by fossil fuel. Varying the settings of the HVDC control strategy as well as the power balance within the offshore port and running several simulations on the power system, the power and voltage profiles in the generation, distribution and transmission of the system can be evaluated in details. Based on the methodology, stability boundaries in the HVDC system can be defined and mapped for reliable operation of the system during unusual and critical scenarios.
