A novel concurrent control scheme of optimal re/active power regulation in a wind farm is proposed in this letter, of which the objective is to minimize the detrimental shortfall of active power during low-voltage-fault events. Distinguished from the existing works, the proposed control scheme incorporates an efficient optimization module into the wind turbine controllers. Specifically, it features the merit that the practical feasibility of tracking the resultant references can be ensured via considering multiple constraints in presence of complex wake interactions. Case studies on a permanent-magnet-synchronous-generator based wind farm built in a joint DIgSILENT-MATLAB platform are carried out to demonstrate the effectiveness of the proposed control scheme.

低电压穿越运行下风电场的并发优化无功功率控制

在这封信中提出了一种新的风电场优化无功/有功功率调节的并发控制方案，其目标是在低压故障事件期间最小化有害的有功功率不足。与现有工作不同，所提出的控制方案将有效的优化模块纳入风力涡轮机控制器。具体而言，它的特点是可以通过考虑存在复杂尾流相互作用的多个约束来确保跟踪合成参考的实际可行性。对在联合 DIgSILENT-MAT​​LAB 平台上建造的基于永磁同步发电机的风电场进行了案例研究，以证明所提出的控制方案的有效性。
