    摘 要:基于連續(xù)潮流法對靜態(tài)電壓穩(wěn)定性問題進行研究,提出了一種協(xié)調(diào)組合參數(shù)化法。在 PV 曲線的不同區(qū)域采用不同的參數(shù)化法,以當前預(yù)測次數(shù)來表征參數(shù)化切換斷點;以“接近校正不收斂”作為組合切換的判據(jù);對切換判據(jù)的閾值進行動態(tài)設(shè)定,以使得組合切換更加合理有效。基于 IEEE 標準節(jié)點系統(tǒng)進行仿真驗證,結(jié)果表明了所提協(xié)調(diào)組合參數(shù)化法的有效性與優(yōu)越性。
    關(guān)鍵詞:連續(xù)潮流法;協(xié)調(diào)組合參數(shù)化法;參數(shù)化切換斷點;切換判據(jù);動態(tài)切換

    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
