    Abstract: 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.
    Key words: continuation power flow method; coordinated combination parameterization method; parameterized switching breakpoint;switching criterion; dynamic switching
