由于风电场的物理面积很大，在相关的电力输送过程中存在一些不确定性和低效问题。为了为公用电网提供所需的无功辅助服务，需要进一步的优化过程，以保持整个系统的可靠性和效率。本文介绍了一种基于风电场线性化系统部件的无功分配策略，该风电场包含一个功率变换系统。此外，我们执行实际的分配过程，以验证该策略的有效性与电磁暂态使用直流软件工具。通过将无功功率分配给附近的风力涡轮机，探索了通过利用风电场的径向结构来减少总的表观功率流。验证过程侧重于比较指定风电场中的正常分配和所提出的方法的输出分布损失。
Owing to the large physical area of a wind farm, some uncertainty and inefficiency issues exist in the related power delivery process. To provide required ancillary services regarding reactive power for the utility grid, further optimization processes are needed to maintain the reliability and efficiency of the entire system. In this paper, we introduce a reactive power assignment strategy that is based on the linearized system components of a wind farm, which comprises a power conversion system. Additionally, we perform realistic assignment processes to verify the effectiveness of this strategy with electromagnetic transients using dc software tool. Reducing the total apparent power flow by utilizing the radial structure of the wind farm is explored by assigning reactive power to nearby wind turbines. The verification process focuses on comparing the loss in output profile of a normal assignment and the proposed method in a designated wind farm.
