摘　　要：基于连续潮流法对静态电压稳定性问题进行研究,提出了一种协调组合参数化法。在PV曲线的不同区域采用不同的参数化法,以当前预测次数来表征参数化切换断点;以“接近校正不收敛”作为组合切换的判据;对切换判据的阈值进行动态设定,以使得组合切换更加合理有效。基于IEEE标准节点系统进行仿真验证,结果表明了所提协调组合参数化法的有效性与优越性。This paper used the methodology of continuous power flow to study the static voltage stability problem and proposed a coordinated combination parameterization method.This research used different parametric methods in dissimilar parts of PV curve so that it could predict the number of times to characterize the breakpoint change of parameterization.Furthermore,“Close to Non-Convergent Correction”is used as a criterion for coordinative combination switching.At the same time,the threshold of the switching criteria is dynamically setting so that the combination switching is reasonable and efficient.Finally,based on the calculation results of the IEEE standard node system,the validity and superiority of the proposed coordinated combination of parameterization methods are verified.The results show the effectiveness and superiority of the proposed coordinated combination parameterization method.
