| 摘 要： | 在分析多故障暂态稳定约束最优潮流(transient stability constrained optimal power flow,TSCOPF)轨迹灵敏度法存在问题的基础上,提出基于单机无穷大母线等值和轨迹灵敏度的暂态稳定度约束最优潮流计算方法.根据单机无穷大母线等值,在暂态稳定约束最优潮流模型中引入严格的暂态稳定判据,并应用轨迹灵敏技术提高计算效率.将故障分为稳定故障、极度稳定故障、一般不稳定故障和极度不稳定故障,分别在暂念稳定约束中分别加以处理,可快速地进行放障筛选.同时,对于小稳定故障不需要寻找临界稳定轨迹,可节省大量的仿真时间.在3机、10机和20机系统上的仿真结果验证了所提出算法的有效性.

| Abstract: | On the basis of analyzing the existing problems in trajectory sensitivity method for transient stability constrained optimal power flow(TSCOPF) under multi-contingency condition,a computational method for TSCOPF was proposed based on one-machine infinite bus equivalent and trajectory sensitivity.According to one-machine infinite bus equivalent,the strict transient stability criterion could be introduced in TSCOPF model,while trajectory sensitivity method was used to enhance computational efficiency.Furtherm... |
