In order to solve the problem of distribution network congestion caused by a large number of distributed power sources and flexible load access to the distribution network, a comprehensive solution for distribution network congestion management based on distribution network reconstruction and marketmechanism is proposed. In the proposed scheme, the flexibility of different types of loads and the respective advantages of the two congestion management methods are used to restructure the distribution network into the market mechanism framework to solve the problem of line and flexible load congestion. This comprehensive solution uses the NSGAII algorithm to solve the blocking problem quickly and effectively, and meet the requirements of the minimum energy cost of the distribution system operator side and the minimum electricity cost of the flexible load side. A simulation study is carried out using a standard IEEE 33 node distribution network test system, which verifies the effectiveness and superiority of the proposed comprehensive scheme.
