Data associated to the publication "Including the power regulation strategy in aerodynamic optimization of wind turbines for increased design freedom"

This dataset contains wind turbine optimization results related to the publication "Iori J, McWilliam MK, Stolpe M. Including the power regulation strategy in aerodynamic optimization of wind turbines for increased design freedom. Wind Energy. 2022.  https://doi.org/10.1002/we.2769 "

There are 3 types of optimization results in this dataset:
- Type A: AEP maximization
- Type B: AEP maximization with thrust penalty
- Type C: AEP maximization with thrust penalty and constraints on the rotational speed and thrust.

The detailed description of each optimization type can be found in the related paper.

For the optimization type A, the same optimization is done for 5 different number of wind speeds: 11, 22, 33, 44 and 88. In addition, the optimization is done in 3 possible ways: using a nested formulation, using a one-level formulation with analytic gradients, and using a one-level formulation with finite-difference gradients. The prefix of each file describes the formulation and the number of wind speed used.

For the optimization type B, the optimization is ran for the one-level and nested formulation.

For the optimization type C, the optimization is ran for the one-level formulation only. The characteristics of the initial design are also reported.

There are 5 types of file, depending on the postfix:
- XXX_planform.dat : reports the planform design (radius, chord, twist, relative thickness)
- XXX_reg_strategy.dat: reports the regulation strategy and the power and thrust evolution in the operational range
- XXX_cp_ct.dat: reports the data to draw the power and thrust coefficient surfaces for the design
- XXX_opt.dat: reports the optimization characteristics at each iteration. It corresponds to the output given by IPOPT. Note that the objective function is the AEP (with or without thrust penalty) with a scaling factor.
- XXX_vr.dat: reports the value of the rated wind speed. This only relevant for the optimization type A, and the optimization type B when the nested formulation is used.

本数据集收录了与发表在《Wind Energy》期刊上的论文《Iori J, McWilliam MK, Stolpe M. Including the power regulation strategy in aerodynamic optimization of wind turbines for increased design freedom. Wind Energy. 2022. https://doi.org/10.1002/we.2769》相关的风力涡轮机优化结果。

数据集中包含三种类型的优化结果：
- 类型A：平均有效功率最大化
- 类型B：在推力惩罚条件下的平均有效功率最大化
- 类型C：在推力惩罚条件下，并对转速和推力施加约束的平均有效功率最大化。

每种优化类型的详细描述均可在相关论文中查阅。

对于优化类型A，针对5种不同的风速数量（11、22、33、44和88）进行了相同的优化操作。此外，优化以3种可能的方式进行：采用嵌套公式、采用单级公式并利用解析梯度，以及采用单级公式并利用有限差分梯度。每个文件的名称前缀描述了所使用的公式和风速数量。

对于优化类型B，仅对单级公式和嵌套公式进行了优化。

对于优化类型C，仅对单级公式进行了优化，并报告了初始设计的特征。

根据后缀，数据集中存在5种类型的文件：
- XXX_planform.dat：报告机翼平面设计（半径、弦长、扭转、相对厚度）
- XXX_reg_strategy.dat：报告调节策略以及操作范围内功率和推力的演变
- XXX_cp_ct.dat：报告绘制设计功率和推力系数表面的数据
- XXX_opt.dat：报告每次迭代的优化特征。它对应于IPOPT给出的输出。请注意，目标函数是包含或不含推力惩罚的平均有效功率，并附带缩放因子。
- XXX_vr.dat：报告额定风速的数值。这仅与优化类型A相关，以及当使用嵌套公式时优化类型B相关。
