Abstract

Controller parameter optimization-based inertia provision methods for wind turbines (WTs) have received much attention, due to their economy and convenience. However, the existing methods fail to consider the effect of multiple controllers on the magnitude-phase characteristics of inertia, which may cause a short support time of WT's inertia response and even deteriorate the system frequency dynamics. To cope with it, this article proposes a collaborative design of multiloop controllers for doubly-fed induction generator (DFIG)-based WTs to optimize inertia characteristics. First, the magnitude-phase characteristics of WT's inertia and their effect on system frequency are analyzed. Then, based on the Sobol' sensitivity analysis method, the dominant influences affecting the magnitude and phase of WTs’ inertia are revealed, respectively. On this basis, a collaborative design method of multiloop controllers is proposed from the perspective of the magnitude-phase characteristics optimization of WT's inertia, which can support system frequency effectively while satisfying constraints of stability as well as rotor kinetic energy. Finally, the analysis and the proposed design method are verified by hardware-in-loop experiments.

为基于 DFIG 的风力涡轮机协同设计多回路控制器以优化惯性特性

基于控制器参数优化的风电机组惯性供给方法因其经济性和便捷性而备受关注。然而，现有的方法没有考虑多个控制器对惯性幅相特性的影响，这可能导致小波变换惯量响应的支持时间短，甚至使系统的频率动力学恶化。针对此问题，本文提出了一种基于双馈感应发电机（DFIG）的WTs多回路控制器的协同设计，以优化WTs的惯性特性。首先，分析了小波惯量的幅相特性及其对系统频率的影响。然后，基于Sobol敏感性分析方法，揭示了影响WTs惯性大小和相位的主要因素。在此基础上，从WT惯量的幅相特性优化的角度，提出了一种多环控制器协同设计方法，在满足稳定性约束和转子动能约束的同时，有效地支持系统频率。最后，通过硬件在环实验验证了分析和提出的设计方法。

期刊介绍： The IEEE Transactions on Power Electronics journal covers all issues of widespread or generic interest to engineers who work in the field of power electronics. The Journal editors will enforce standards and a review policy equivalent to the IEEE Transactions, and only papers of high technical quality will be accepted. Papers which treat new and novel device, circuit or system issues which are of generic interest to power electronics engineers are published. Papers which are not within the scope of this Journal will be forwarded to the appropriate IEEE Journal or Transactions editors. Examples of papers which would be more appropriately published in other Journals or Transactions include: 1) Papers describing semiconductor or electron device physics. These papers would be more appropriate for the IEEE Transactions on Electron Devices. 2) Papers describing applications in specific areas: e.g., industry, instrumentation, utility power systems, aerospace, industrial electronics, etc. These papers would be more appropriate for the Transactions of the Society which is concerned with these applications. 3) Papers describing magnetic materials and magnetic device physics. These papers would be more appropriate for the IEEE Transactions on Magnetics. 4) Papers on machine theory. These papers would be more appropriate for the IEEE Transactions on Power Systems. While original papers of significant technical content will comprise the major portion of the Journal, tutorial papers and papers of historical value are also reviewed for publication.
