Stability Monitoring and Control of Power Systems

将开发在压力环境下运行的电力系统的电压稳定监测和控制技术。重点将放在使用探头信号来检测即将失去的稳定性，并将所产生的警告信号用于闭环系统控制以实现系统稳定。通过这种基于信号的方法，减少了对准确模型可用性和大量离线计算的依赖。新的控制律将被开发用于稳定电压失稳附近的电力系统。在以前的研究中，PI和他的学生对分叉控制理论做出了重要贡献，最近，他们将这一理论与稳定性监测结合起来。在这项拟议的研究项目中，这些结果将应用于压力电网中临时性不稳定的检测和控制。与以前工作的一个主要区别是，强调在实际遇到不稳定之前检测它们，并通过信号而不是纯粹基于模型的技术实现这一点。此外，由电力系统应用引发的分析问题自然也将对该理论作出新的贡献。

Techniques for the monitoring and control of voltage stability in electric power systems operating in a stressed environment will be developed. Emphasis will be placed on the use of probe signals to detect impending loss of stability and using the resultin warning signals in closed-loop control for system stabilization. Through such a signal-based approach, reliance on availability of accurate models and on extensive off-line computations is reduced. New control laws for stabilizing power systems near voltage instability will be developed. In previous research, the PI and his students have made important contributions to the theory of bifurcation control and, more recently, have coupled this with stability monitoring. In this proposal research project, these results will be applied to detection and control of impending instability in stressed electric power networks. One major departure from previous work is the emphasis on detection of instabilities before they are actually encountered, and achieving this with a signal- rather than purely model-based technique. Additionally, it is expected that new contributions to the theory will also naturally result from analytical problems motivated by the power system application.
