Intermediate Steps in Developing a Framework for Power System Operation Closer to Security Limits (SGER)

这是一个关于一个有争议的主题的SGER项目：电力系统的暂态稳定方法。调查人员正在研究暂态稳定性的新指标和措施，包括安全裕度、关键参数、关键事故、脆弱性和压力指数的措施。该项目包括能够直接计算这些参数的方法。其他项目重点包括稳定性指标的专家系统分类和在线方法。该项目具有争议性，因为它与传统方法及其用于暂态稳定评估的方法不一致。

This is a SGER project on a controversial subject: transient stability methodology for electric power systems. The investigators are examining new indices and measures for transient stability including measures of security margin, critical parameters, critical contingencies, vulnerability, and indices of stress. The project includes methodologies which are capable of direct calculation of these parameters. Additional project foci include expert system sorting of stability indices and on-line methodologies. The project is controversial in that it is at odds with traditional methods and their use for transient stability assessment.
