摘　　要：在应用连续潮流法进行电压稳定性分析之中,提出了一种最优参数化组合方法。该方法利用负荷功率变化量绝对值对PV曲线进行区域划分,并在各个区域对各种参数化方法进行了分析研究,得出了在整个区域的最优参数化方法组合。这种最优参数化组合方法不仅能够提高连续潮流法的计算效率,而且还适用于交直流系统,特别是能够保证并加速潮流计算的收敛。通过对IEEE118节点交流标准测试系统以及交直流混合系统的分析计算,验证了该方法的有效性。This paper proposes an optimal combination of parameterization in voltage stability analysis with continuous power flow.In this method,the PV curve is divided into three zones by the absolute value of the variation of load power,and then based on the zone division,the parameterization is analyzed and selected in each part so as to get the optimal combination of the parameterization in the whole zone.This method can not only improve the computational efficiency of the continuous power flow,but also is suitable for AC/DC hybrid system,ensuring and accelerating the convergence of the power flow computation.By applying the optimal combination of the parameterization to IEEE 118-bus test system and AC/DC hybrid system for simulation,the results show the validity of the proposed method.
