| 摘 要： | 阐述了一种改进的连续潮流法。该方法预测过程中采用了非线性预测,在功率极限点附近不需要减小步长,校正过程中采用局部参数法求解校正方程,从而减少了绘制PV曲线的时间;潮流计算采用牛拉法,保证了PV曲线绘制过程中的稳定性。通过对IEEE 39和IEEE 118节点测试系统进行仿真计算,取得了良好的计算结果,从而验证了本算法的有效性和快速性。

| Abstract: | In this paper,an improved continuation power flow method is presented. Nonlinear predictor is used in the process of predictor. It does not have to take smaller steps near the nose point. Locally parameterized algorithm is used in the corrector. The new method for drawing a PV curve has advantage in terms of computation speed. Newton-Raphson power flow method is used which plays a stable role in the process of drawing a PV curve. The results obtained with the new method for the IEEE 39-bus and 118-bus test ... |
