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.
