| 摘 要： | 针对区域电网难以通过获取外网实时状态信息来实施静态电压稳定控制的问题，提出了一种基于外部网络单点等值，并考虑区域电网静态电压稳定裕度的广域切负荷控制策略。首先采用戴维南等值方法对区域电网的外部系统进行等值。然后以区域电网在负荷增长状态下的潮流等式约束作为静态电压稳定约束条件，建立了全二次最小切负荷优化模型，并采用半光滑...

| Abstract: | In allusion to the problem that it is difficult for regional power network to implement the strategy to response static voltage stability by acquiring real-time status information of exterior power network,a wide-area load shedding control strategy,which is based on the equivalence of single-bus and considering static voltage stability margin of regional power network,is proposed.Firstly,the exterior system equivalence of regional power network is carried out by Thevenin equivalence;then taking the power fl... |
