本文介绍了一种通过发电重新调度来缓解大规模互联电力系统区域间振荡的新方法。通过搜索从当前操作条件到具有所需振荡模式阻尼比的目标操作条件的最短距离，得出最佳缓解程序。基于敏感性的方法用于选择最有效的发电机进行发电重新调度，并训练决策树以近似由所选发电机表征的空间中的安全边界。可以通过解决由决策树规则提供边界约束的优化问题来找到最佳操作规则。该方法在西部电力协调委员会（WECC）179总线简化模型上进行了测试，仿真结果证明了基于决策树的方法的有效性，并在实时运行中显示出良好的应用前景。
This paper introduces a new method for mitigating inter-area oscillations of a large scale interconnected power system by means of generation re-dispatch. The optimal mitigation procedures are derived by searching for the shortest distance from current operating condition to a targeted operating condition with the desired damping ratio of the oscillation mode. A sensitivity-based method is used to select the most effective generators for generation re-dispatch and decision tree is trained to approximate the security boundary in a space characterized by the selected generators. The optimal operational rules can be found by solving an optimization problem where the boundary constraints are provided by the decision tree rules. This method is tested on a Western Electricity Coordinating Council (WECC) 179-bus simplified model and simulation results have demonstrated the validity of the decision-tree-based method and shown promising application in real time operation.
