| Abstract |
This paper presents findings from a comparative study on LCoE (levelized cost of energy) impact from various configurations of electrical power conversion in on-shore wind turbines. All comparisons are made against a baseline configuration, based on proprietary models and input data, thus boundary conditions and assumptions apply, which do not necessarily translate to other manufacturers of wind turbines and electrical power conversion solutions. In our analysis, we asked the question: which power conversion topology and converter building block size can offer the best LCoE reduction across a broad range of wind turbine products employing uniform architecture_ And which contributions to life-cycle cost dominate_ The methodology is explained, and results indicate, among those analysed, that a scalable, modular medium-voltage converter platform should be employed in a turbine down-tower architecture. |
