论文摘要
电力系统限制电力传输能力的界限虽然是领带线的振荡。为了进行稳定的操作，部署大区域动力系统稳定器可提供足够的阻尼。但是，由于反馈通过通信网络，它带来了诸如其他通信层和网络安全问题之类的挑战。为了解决这个问题，提出了一个用于从本地测量中综合远程信号的框架，作为广阔的电力系统稳定器中的反馈。在两个面积基准系统的案例研究中，使用观察者的不同变体合成远程信号。提出的框架可以改善静态输出反馈控制器的区域间振荡的阻尼。提出的框架应有助于设计智能网格中的攻击弹力控制器设计。
Inter-area oscillations in power system limit of power transfer capability though tie-lines. For stable operation, wide-area power system stabilizers are deployed to provide sufficient damping. However, as the feedback is through a communication network, it brings challenges such as additional communication layer and cybersecurity issues. To address this, a framework for synthesizing remote signal from local measurement as feedback in the wide-area power system stabilizer is proposed. The remote signal is synthesized using different variants of observers in a case study of two-area benchmark system. The proposed framework can improve the damping of inter-area oscillations for static output feedback controller. The presented framework should help to design attack-resilient controller design in smart grid.
