Abstract

Reinforcement learning (RL) algorithms are expected to become the next generation of wind farm control methods. However, as wind farms continue to grow in size, the computational complexity of collective wind farm control will exponentially increase with the growth of action and state spaces, limiting its potential in practical applications. In this Letter, we employ a RL-based wind farm control approach with multi-agent deep deterministic policy gradient to optimize the yaw manoeuvre of grouped wind turbines in wind farms. To reduce the computational complexity, the turbines in the wind farm are grouped according to the strength of the wake interaction. Meanwhile, to improve the control efficiency, each subgroup is treated as a whole and controlled by a single agent. Optimized results show that the proposed method can not only increase the power production of the wind farm but also significantly improve the control efficiency.

基于强化学习的风电场集体偏航控制分组策略
强化学习(RL)算法有望成为下一代风电场控制方法。然而,随着风电场规模的不断扩大,风电场集体控制的计算复杂度将随着动作和状态空间的增长而呈指数级增长,从而限制了其在实际应用中的潜力。在这封信中,我们采用了一种基于 RL 的风电场控制方法,该方法具有多代理深度确定性策略梯度,可优化风电场中分组风力涡轮机的偏航操纵。为降低计算复杂度,风电场中的涡轮机根据尾流相互作用的强度分组。同时,为了提高控制效率,每个分组都被视为一个整体,由单个代理进行控制。优化结果表明,所提出的方法不仅能提高风电场的发电量,还能显著提高控制效率。
