摘　　要：针对常规的连续潮流计算在求取P-V曲线时存在的缺点,提出了一种连续潮流计算的改进算法。该改进算法通过采用单位化处理切线预测向量、以切线预测向量的内积确定预测方向以及变步长控制等措施,提高了连续潮流计算在求取P-V曲线时的准确性和计算效率。Matlab仿真验证了该改进算法的有效性。Aiming at the shortcomings of conventional continuous power flow calculation in obtaining P-V curve,this paper proposes an improved algorithm for continuous power flow calculation, which applies some measures including unitization of processing tangent prediction vector,the inner product of tangent prediction vectors used to determine prediction direction and variable step size control. In this way, the accuracy and computational efficiency is improved for the continuous power flow calculation in obtaining the P-V curve. The Matlab simulation results have verified the effectiveness of the improved algorithm.
