风能的更高渗透率对风能转换系统（WECS）的电网支持和功率管理功能提出了越来越高的需求。研究了一种集成有功功率管理和无功功率补偿功能的中压固态Transformer（SST）-永磁同步发电机系统。具体而言，WECS包括风力涡轮机，SST，和直流负载。此外，提出了一种分布式电源管理算法的直流网络与当地的风力涡轮机控制纳入实现独立的功率平衡的条件下，无需能量存储或通信设备。所考虑的方案包括并网模式、孤岛模式和模式转换。仿真结果验证了该策略的有效性。此外，使用缩小的实验室原型的概念进行了实验验证。
The higher penetration of wind energy poses increasing demand for grid support and power management functions of a wind energy conversion system (WECS). This paper investigates a medium-voltage solid-state transformer (SST)-interfaced permanent magnet synchronous generator system with integrated active power management and reactive power compensation functions. Specifically, a WECS consisting of wind turbines, SSTs, and dc loads is presented. In addition, a distributed power management algorithm is proposed for a dc network with local wind turbine controls incorporated to achieve a self-contained power-balanced condition without the need for energy storage or communication devices. Scenarios considered include the grid-connected mode, the islanding mode, and the mode transitions. Simulation results are provided to verify the effectiveness of the proposed strategy. Additionally, the concept is experimentally verified using a scaled-down laboratory prototype.
