Abstract

This research work focuses on addressing the challenges of controlling a wind energy conversion system (WECS) connected to the grid, particularly when faced with variable wind speed profiles. The system consists of a Doubly-Fed Induction Generator (DFIG) connected to the grid through an AC/DC/AC converter, along with a Li-ion battery storage system connected to the Back-to-Back converter DC link via a DC/DC converter. The non-linearity and internal parametric variation of the wind turbine can negatively impact energy production, battery charging performance, and battery lifespan. To overcome these issues, the study proposes a robust control approach called Integral action Sliding Mode Control (ISMC) to enhance the dynamic performance of the WECS based on DFIG. Additionally, the battery charging and discharging controllers play a crucial role in efficiently distributing power to the grid and storage unit based on the battery's state of charge, extracted energy, and power injected into the grid. Two current regulation modes, buck charging and boost discharging, are employed to ensure proper energy distribution. Furthermore, a storage system energy management algorithm is implemented to ensure battery safety during one of the charging modes. The effectiveness and robustness of the proposed control method were validated through simulations of a 1.5 MW wind power conversion system using Matlab/Simulink. The results confirmed the method's efficiency and efficacy.
卷风条件下基于 DFIG 的 WECS 和储能系统的鲁棒控制系统
这项研究工作的重点是解决与电网相连的风能转换系统(WECS)的控制难题,尤其是在风速变化的情况下。该系统包括一个通过交流/直流/交流转换器与电网相连的双馈感应发电机(DFIG),以及一个通过直流/直流转换器与背对背转换器直流链路相连的锂离子电池存储系统。风力涡轮机的非线性和内部参数变化会对能源生产、电池充电性能和电池寿命产生负面影响。为了克服这些问题,该研究提出了一种名为 "积分动作滑动模式控制"(ISMC)的稳健控制方法,以提高基于 DFIG 的 WECS 的动态性能。 此外,电池充放电控制器在根据电池的充电状态、提取的能量和注入电网的电量向电网和存储单元有效分配电能方面起着至关重要的作用。该系统采用降压充电和升压放电两种电流调节模式,以确保适当的能量分配。此外,还实施了一种存储系统能量管理算法,以确保在其中一种充电模式下的电池安全。通过使用 Matlab/Simulink 对 1.5 兆瓦风能转换系统进行仿真,验证了所提控制方法的有效性和稳健性。结果证实了该方法的效率和有效性。
