Optimization of offshore wind turbines layout considering wake effect. Issue 1 (1st October 2022) - Li, Li-Xia
Abstract: In the actual construction of an offshore wind farm, the layout of wind turbines directly affects the flow characteristics of each wind turbine. When the wind passes through the upstream unit, the work done at the hub of the downstream fan decreases, resulting in the wake effect. Therefore, on the premise of considering the wake flow, it is of great significance to study the optimization of fan arrangement. The research and selection of reasonable wind turbine arrangements have a significant effect on power generation efficiency and power output. In this paper, the improved Gauss model is used to simulate the wake flow, and the cost model that is more close to the actual construction is selected. By taking the number and distance of wind turbines as variables and the cost generated as the objective function, the research is carried out. The research is carried out in the process of automatic optimization through a particle swarm optimization algorithm.
