Optimal Topology and Repowering Time for Offshore Wind Turbines

Abstract : Finding the optimal repowering strategies for offshore wind turbines is a major issue within the wind industry worldwide. This paper deals with series, parallel and series-parallel systems that each component has several versions available in the market. We present a model for finding the best topology and optimal time for repowering systems based on cost and availability functions. An application on offshore wind turbine systems as a series-parallel system is given.
