【摘要】 电力系统潮流可行域(PFFR)是一种评估系统静态安全的有效手段。本文在作者以前工作的基础上,展开了对于不同的子空间——负荷注入子空间与发电注入子空间——中潮流可行域边界所具有的不同的拓扑性质的讨论。随后,本文讨论了处理高维空间中潮流可行域的思路,分别提出了计算最近／最远边界点的新算法。本文关于发电注入空间潮流可行域边界拓扑性质的结论也被用来解释最远边界点算法的多解性。更多还原

【Abstract】 Power Flow Feasibility Region(PFFR)is regarded as one of the most promising frameworks for static security assessment of power systems.With the help of our pervious works,we analysis different topological properties of boundaries of PFFR in two sub-regions which are so called“Region of Load Injection Space(RLIS)”and“Region of Generator Injection Space (RGIS)”.The concerns are focused on the special topological property of PFFR in RGIS.Then,we discuss how to deal with hish-dimension PFFR,and new algorithms for computing closest/farthest boundary point are suggested.Our conclusion about topological property of PFFR is also used to explain multi-solution of the farthest boundary point algorithm.更多还原
