| 摘 要： | 结合前推回代法的特点,分析研究了各种类型分布式电源在前推回代潮流计算中的数学模型。针对前推回代法对PV节点和环网失效的问题,提出了依据节点电阻矩阵、节点电抗矩阵及电压偏差对P、V恒定型分布式电源和环网断点功率修正方法,设计了适合于分布式电源和环网的灵活节点编号方法,给出了改进前推回代潮流算法的执行过程。通过20节点系统和IEEE90节点系统的仿真,对所提出算法的适应性、计算速度、收敛性等进行了分析,结果表明本文提出模型和方法能够快速、方便求解含多电源多类型的配电网潮流。

| Abstract: | Integrated with the characteristics of the back/forward sweep,this paper presents the various models of distributed generators (DGs) adapted to the back/forward sweep method. Considering the limits of the back/forward sweep for solving PV node and meshed network,their power correction equations are put up based on resistance matrix,reactance matrix and mismatch of voltage magnitude,planning the flexible nodal numbering scheme suited for DGs and meshed network,giving the procedure of the improved back/forwar... |
