摘要:

以节点注入功率和PV电压运行曲线为基础,分析了几种概率潮流模型在迭代算式和计算精度上的差别,包括线性化模型、近似二阶模型和完整二阶模型.各种模型中,计及方差对均值的修正,同时还采用扩展的雅克比矩阵考虑了PV点和平衡点的电压曲线.试算结果表明,长期以来备受关注的近似二阶模型并不能保证电压实部方差的精度,而采用完整二阶模型计算的电压均值和方差具有相当高的精度.

Abstract:

Based on the operation curves of nodal injection power and PV voltage, the differences in iterative calculation and calculation accuracy of several probabilistic power flow models are analyzed, including linearization model, approximate second-order model and complete second-order model. In various models, the correction of variance to mean is taken into account, and the extended Jacobi matrix is also used to consider the voltage curves of the PV point and the equilibrium point. The trial results show that the approximate second-order model that has attracted much attention for a long time cannot guarantee the accuracy of the real variance of voltage, while the voltage mean and variance calculated by the complete second-order model have quite high accuracy.
