Abstract

Considering the actual engineering requirements, this paper proposes an intelligent offshore-wind-farm layout optimization approach under geometrical constraints. The proposed approach adopts the Gaussian wake model to calculate the velocity deficit, and maximizes the wind-farm annual energy production （AEP） with a differential evolution algorithm, which can meet various geometrical constraints in the offshore-wind-farm layout optimization. Then this approach is used to optimize the wind turbine layout for a practical offshore wind farm under 3-, 4-, 7-rows geometrical constraints. The optimized results indicate that compared with the original layout scheme, the layout optimization scheme can increase the AEP of the wind farm by 2.13%-2.64% when considering the increase of cable laying cost. Further analysis suggests that the setup of potential solution number should consider the difficulty of getting the optimized result for this intelligent method.
