一种基于局部测量的区域间振荡控制框架

A Framework to Control Inter-Area Oscillations with Local Measurement

Abhilash Patel

摘要:

电力系统区域间振荡对联络线输电能力的限制。为了稳定运行,部署广域电力系统稳定器以提供足够的阻尼。然而,由于反馈是通过通信网络进行的,因此会带来额外的通信层和网络安全问题等挑战。为了解决这个问题,提出了一种用于从本地测量合成远程信号作为广域电力系统稳定器的反馈的框架。在两区域基准系统的案例研究中,使用不同的观测器变体来合成远程信号。所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。所提出的框架将有助于设计攻击弹性控制器的设计在智能电网。

英文摘要:

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.
