Study on Submarine Cable Selection Considering Loss Reduction Potential and Economy

With the promotion of the construction of a new power system with new energy as the main body, the island area is expected to become a key development area with its rich scenery resources. The scale of submarine cable laying will be greatly increased. More attention has been paid to the loss reduction of distribution network in island areas. In this paper, from the perspective of submarine cable selection, the life cycle cost model of submarine cable is constructed while considering reducing the loss of submarine cable itself. Finally, through the comparison and analysis of different submarine cable losses and economy, it provides a reference for future submarine cable selection.
