Presidential Young Investigator Award: Nonlinear Security and Control Techniques for Power Systems

本工作涉及到动力学中的几个问题的研究 大型电力系统的安全评估。 的 重点是电压不稳定问题，并建议 为这个问题制定概率安全措施。 沿着 这是一项对吸引力区域性质的调查 在涉及无功潮流和电压的模型中， 方面的影响. 初步调查显示， 吸引力和不稳定平衡点是完全不同的， 包括电压动态的模型。 对这个特别感兴趣的是 工作将是任何技术开发的系统， 其包括可控高压DC链路。

This work involves investigation into several problems of dynamic security assessment for large-scale electric power systems. The emphasis is on the problem of voltage instabilities and proposes to develop a probabilistic security measure for this problem. Along with this is an investigation into the nature of the regions of attraction of equilibria in models that involve reactive power flow and voltage effects. Initial investigations have shown that the regions of attraction and unstable equilibria points are radically different in models that include voltage dynamics. Of particular interest in this work will be extensions of any techniques developed to systems that incorporate controllable high voltage dc links.
