【摘要】 在电力系统动态安全分析中,基于能量函数的PEBS/BCU方法应用时,识别穿越PEBS界面的出口点方法包括射线法和梯度法。鉴于这两种方法应用的局限性,论述了新的动态梯度法,以提高识别出口点的准确性。并以电科院6机22节点系统为例进行了主导不稳定平衡点的计算。更多还原

【Abstract】 In power system dynamic security assessment, based on the PEBS/BCU method, the dominant methods for detecting the exit point across PEBS are the ray and gradient methods. For improving the reliability of PEBS detection, a novel dynamic gradient method is illustrated in this paper. The calculating results for identifying CUEP are given in the six-generator twenty-two bus test system.更多还原
