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.

将开发在压力环境中运行的电力系统中的电压稳定性的监测和控制技术。重点将放在使用探针信号来检测即将发生的稳定性损失，并使用闭环控制系统稳定的结果警告信号。通过这种基于信号的方法，减少了对精确模型的可用性和对大量离线计算的依赖。将开发用于稳定接近电压不稳定的电力系统的新的控制律。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，最近又将其与稳定性监测相结合。在本研究计划中，这些结果将应用于检测和控制即将发生的不稳定性，在强调电力网络。与以前的工作的一个主要区别是强调在实际遇到不稳定性之前检测不稳定性，并使用信号而不是纯粹基于模型的技术来实现这一点。此外，预计新的贡献理论也将自然产生的动力系统应用程序的分析问题。
