摘要(Abstract)：

根据配电网三相不平衡的实际情况,为准确计算各种分布式电源(distributed generation,DG)并入配电网后的潮流问题,文章基于前推回代法,提出了可处理PV和PQ节点模型DG的三相不平衡潮流算法。按照配电网拓扑结构,利用支路分层技术,加快了潮流计算速度。在处理PV节点模型DG时,将电压正序分量幅值作为电压调节参数,计算电压正序分量幅值和额定电压幅值差,得到PV节点的无功补偿量,将DG由PV节点运行模型转换为PQ节点运行模型。IEEE34节点系统算例结果验证了该算法的正确性。最后,通过分析DG对电压的调节和无功补偿能力,研究了不同类型DG对配电网电压的影响。
