摘要
本文提出了一种基于几何参数化求取PV曲线方法。该方法应用预测校正法的连续潮流算法,采用几何参数化,从而消除了在功率极限附近雅可比矩阵奇异的现象,有效地改变了收敛方向,可以精确获得电压稳定极限和完整的PV曲线。应用该算法对IEEE39节点和IEEE118节点的电力系统进行了仿真计算,取得良好的计算结果,证实了该算法的有效性。
This paper presents an efficient geometric method trace the whole PV curve.The method is based on predictor-corrector method, adoping the geometric correction,effectively changed the direction of convergence without encounting the numerical difficulty of power Jacobian matrix singular phenomenon,can get accurate limit of voltage stability and the entire PV curve. The result for IEEE 39-bus and 118-bus test system are calculated and analysed,confirmed the effectiveness of thealgorithm.
