| 摘 要： | 提出一种基于MonteCarlo仿真和静态电压稳定域方法的概率最大输电能力(TTC)分层计算模型,实现了综合考虑负荷、发电机出力和设备故障不确定性因素的概率TTC快速计算。针对设备故障引起的电压稳定域边界的改变,利用阻尼牛顿法从故障前稳定域边界点直接计算得到故障后稳定域边界点,用切平面描述故障后稳定域的局部从而快速得到该故障情况下的TTC。

| Abstract: | A layered TTC(Total Transfer Capability)calculation model is developed based on Monte Carlo simulation and the SVSR(Statistic Voltage Stability Region)method.Load,generator output and device contingencies uncertainties are considered in this model.The post-contingency SVSR partial boundary is described by a plane,whose tangent point is directly calculated from the pre-contingency point by Damped Newton Method.The advantages of this proposed method are illustrated by an application to a IEEE RTS-118 system. |
