Cables and Electrical Components
Presentation Description: Although the benefits of offshore wind (OSW) energy have been globally recognized, its grid integration technologies are not yet fully matured and understood, specifically when it comes to HVDC solutions in North America.
Presenter(s) will rely on their international and domestic experience to illustrate a methodology, and their lessons learned, to effectively evaluate and compare various offshore wind integration solutions for a given OSW project. Two recent case studies related to U.S. North East OSW development will be presented. The evaluation methodology considers multiple quantitative and qualitative factors. Firstly, a detailed qualitative assessment matrix (DQAM) is introduced. For HVAC solution, this includes selection of optimal voltage level, cable configuration & technology, reactive power compensation strategy, offshore & onshore AC platform design, spatial requirement and market incentives. Similarly, for HVDC solution, DQAM considers optimal voltage level based on the planned transferred MW, cable & converter technology, HVDC link types, offshore & onshore converter station and market incentives. These preliminary selections are further evaluated using a quantitative approach considering reliability, ampacity, energy loss, reactive power needs, capital as well as life-time operating cost. Finally, shortlisted design solutions are ranked considering the delivered OSW energy based on the availability of each solution and annualized capital and operating cost.
