摘要
以IEEE24与IEEE118两个系统为例,提出了一种基于快速解耦法的改进连续潮流算法,将PV曲线分段求取,从基本工况开始增加负荷,采用非线性预测与快速解耦法求解潮流,直至不能获得潮流解,并采用切线预测与连续快速解耦法求解潮流获得完整的PV曲线。仿真计算结果表明,该算法快速、有效、准确、精度高,具有实用价值。
Taking the IEEE 24 and IEEE 118 system for an example, an improved continuation method based on fast decoupled power flow is proposed. PV curve is solved with piecewise method. Nonlinear prediction and fast decoupled power flow method are used to solve power flow by increasing load from the basic condition to that of not obtaining the solution of power flow, The tangent prediction and continuation fast decoupled power flow method are applied to obtain the whole PV curve. The improved algorithm has characteristics of fast computation speed, accuracy, effectiveness and high precision. It has practical value.
