A Simplified Modeling Approach of Floating Offshore Wind Turbines for Dynamic Simulations

Currently, floating offshore wind is experiencing rapid development towards a commercial scale. However, the research to design new control strategies requires numerical models of low computational cost accounting for the most relevant dynamics. In this paper, a reduced linear time-domain model is p...
