论文摘要
在本文中，我们提出了AC微电网系统及其网络证券解决方案系统中二级频率调节的共同设计。我们称二级频率调节器是微自动生成控制（Micro-AGC），以突出其与大量功率系统中的AGC相同的功能。我们确定了感官挑战和微型AGC面临的网络威胁。为了应对感官挑战，我们通过利用微电网动力学的排名一项缺陷属性引入了新的微电网模型。该模型用于构成易于实现的最佳微型AGC控制问题，因为它不需要快速频率测量。针对拟议的Micro-AGC开发了针对错误数据注入（FDI）攻击检测和缓解措施的端到端网络安全解决方案。通过引入数据驱动的建模方法，可以消除应用现成算法进行网络攻击检测的前端障碍。最后，我们提出了一个基于观察者的微电网和AC微电网系统中的协作缓解方案的基于观察者的纠正控制。我们展示了在网络攻击过程中微电网系统系统的协作作用。在两个网络微电网的系统中测试了所提出的网络弹性微型AGC的性能。
In this paper we propose a co-design of the secondary frequency regulation in systems of AC microgrids and its cyber securty solutions. We term the secondary frequency regulator a Micro-Automatic Generation Control (Micro-AGC) for highlighting its same functionality as the AGC in bulk power systems. We identify sensory challenges and cyber threats facing the Micro-AGC. To address the sensory challenges, we introduce a new microgrid model by exploiting the rank-one deficiency property of microgrid dynamics. This model is used to pose an optimal Micro-AGC control problem that is easily implemented, because it does not require fast frequency measurements. An end-to-end cyber security solution to the False Data Injection (FDI) attack detection and mitigation is developed for the proposed Micro-AGC. The front-end barrier of applying off-the-shelf algorithms for cyber attack detection is removed by introducing a data-driven modeling approach. Finally, we propose an observer-based corrective control for an islanded microgrid and a collaborative mitigation schemes in systems of AC microgrids. We demonstrate a collaborative role of systems of microgrids during cyber attacks. The performance of the proposed cyber-resilient Micro-AGC is tested in a system of two networked microgrids.
