考虑约束变化的风电场尾流优化

考虑约束变化的风电场尾流优化
摘要：新能源电站投资巨大，故发电效率非常重要。尾流效应是影响风电场发电效率的重要因素，然而现有的尾流优化算法忽略了风速变化对叶尖速比(tip speed ratio ，TSR)调节范围的影响，这可能导致优化结果实际无法实现。考虑到处于尾流区域内的风机，其优化变量可行区间将随前排风机的优化而变动，论文对此变动进行了建模，并提出了一种考虑约束变动的优化算法以提高风电场尾流优化的准确性。通过对比有无考虑约束变化的两种算法在相同环境下的仿真结果，验证了所提算法的有效性。

Abstract:The investment in new energy power stations is vast, so the power generation efficiency is critical. The wake effect is an important factor affecting the power generation efficiency of wind farms. However, the existing wake optimization algorithms ignore the influence of wind speed change on the regulation range of tip speed ratio (TSR), which may lead to the actual failure of optimization results. Considering that the feasible interval of the optimization variables of the turbine in the wake area will change with the optimization of the front turbines. This paper models that change and proposes an optimization algorithm considering the constraint change to improve the accuracy of the wake optimization of the wind farm. The effectiveness of the proposed algorithm is verified by comparing the simulation results of the two algorithms with or without constraint changes in the same environment.
