Integrated Control of Floating Offshore Wind Farms with Reconfigurable Layouts

Abstract. This study proposes an integrated control method for floating offshore wind farms (FOWFs) that seeks to maximize farm-level power output or regulate it to a prescribed reference while mitigating wake-induced losses. To achieve these objectives, the method integrates existing control strategies: turbine repositioning, wake steering, power derating, and dynamic wake mixing, within a unified framework that adaptively selects the most effective combination based on wind conditions and control goals. This integration is motivated by the fact that individual strategies may be effective only under specific conditions or broadly effective but not always optimal, whereas their coordinated use can deliver robust performance improvements across a broad range of operating scenarios. The framework targets FOWFs with reconfigurable layouts, where turbines are mounted on floating platforms anchored to the seabed with sufficiently long and slack mooring lines, allowing them to shift within a certain range and thereby enabling controlled positional adjustments. Numerical simulations using the flow redirection and induction in steady state (FLORIS) engineering wake model show that the integrated method consistently outperforms any individual strategy. These findings highlight the potential of integrated control to enhance the efficiency, flexibility, and adaptability of FOWFs, offering a promising pathway to overcome the limitations and improve the performance of standalone control methods.
