摘　　要：分布式电源高比例渗透和柔性负荷的灵活调度给配电网安全运行带来了极大挑战。分布式调度可以减轻配电系统运营商的运行难度,保障用户隐私,提升市场竞争。首先,建立了配电系统运营商和产消者之间的二次规划优化模型,采用基于迭代配网节点电价的分布式算法确定配电系统运营商和产消者之间的电价。其次,引入金融输电权概念用于平抑阻塞电价风险,防止节点阻塞费用补偿负作用于阻塞管理。最后在修改的IEEE33节点配电网测试系统上验证了所提方法在阻塞管理上的有效性。The high penetration of distributed generation(DG)and flexible loads dispatch has brought great challenges to the safe operation of the distribution network.Distributed scheduling can reduce operating difficulty of the distribution system operator(DSO),protect user privacy and enhance market competition.First,a quadratic programming model between the DSO and prosumers is established.The distributed algorithm based on the iterative distribution locational marginal prices(iDLMP)is adapted to determine the electricity price between the DSO and prosumers.Secondly,the concept of financial transmission rights(FTR)is introduced to suppress the risk of congestion price and prevent congestion cost compensation from negatively contributing to congestion management.Finally,the effectiveness of the proposed method in congestion management is verified on a modified IEEE33 node distribution network test system.
