论文摘要
我们考虑通过基于逆变器的资源（IBR）控制低惯性功率系统的频率的问题，这些资源弱连接到网格。我们提出了一种新型的网格形成控制策略，即所谓的频率构成控制，旨在塑造同步发电机（SG）的频率响应以加载扰动，从而有效阻止突然的频率下降。我们的解决方案放松了文献中的几个现有假设，并且能够在峰值功率需求和最大频率偏差之间进行权衡。最后，我们分析了对网络参数不完善的知识的鲁棒性，同时尤其强调了对这些参数进行准确估计的重要性。
We consider the problem of controlling the frequency of low-inertia power systems via inverter-based resources (IBRs) that are weakly connected to the grid. We propose a novel grid-forming control strategy, the so-called frequency shaping control, that aims to shape the frequency response of synchronous generators (SGs) to load perturbations so as to efficiently arrest sudden frequency drops. Our solution relaxes several existing assumptions in the literature and is able to navigate tradeoffs between peak power requirements and maximum frequency deviations. Finally, we analyze the robustness to imperfect knowledge of network parameters, while particularly highlighting the importance of accurate estimation of these parameters.
