Abstract

In this article, a power generation and energy storage integrated system based on the open-winding permanent magnet synchronous generator (OW-PMSG) is proposed to compensate for wind power fluctuations and reduce system costs. First, a new integrated topology of power generation and energy storage is constructed to support the flexibility of energy flow in the system through OW-PMSG. Then, the control principles of the semi-controlled OW-PMSG system are analyzed, and the bidirectional energy flow between energy storage and the permanent magnet synchronous generator (PMSG) is fulfilled by controlling the voltage vector generated by the energy storage converter. Furthermore, the acceptable range of the dc-bus capacitor voltage is calculated to guarantee effective modulation. On this basis, a stable power control strategy based on voltage regulation is proposed to maintain the constant power transmitted to the grid. The effectiveness of the proposed scheme is verified through experiments.

基于开式绕组永磁同步发电机的发电储能一体化系统

本文提出了一种基于开绕组永磁同步发电机（low - pmsg）的发电储能一体化系统，以补偿风电的波动，降低系统成本。首先，构建了一种新的发电和储能集成拓扑结构，通过低功率pmsg支持系统中能量流的灵活性；然后，分析了半控制的低压永磁同步发电机系统的控制原理，通过控制储能变换器产生的电压矢量来实现储能与永磁同步发电机（PMSG）之间的双向能量流动。此外，还计算了直流母线电容电压的可接受范围，以保证有效调制。在此基础上，提出了一种基于电压调节的稳定功率控制策略，以保持输电网功率恒定。通过实验验证了该方案的有效性。
