Abstract: This paper proposes a day-ahead congestion management scheme for distribution networks with the dynamic tariff (DT) and re-profiling products. In the proposed scheme, the DT method is first employed to resolve congestion before the energy bidding process and the re-profiling product is used afterwards to resolve remaining congestion through the flexibility market. Moreover, the original DT model is relaxed to resolve the possible infeasible issue of the DT problem and set a maximum limit for DTs. With the combination of the DT and re-profiling product, the proposed scheme can resolve congestion more effectively while ensuring that the DTs are within an acceptable range. Two case studies were conducted with the Roy Billinton Test System (RBTS) to validate the effectiveness of the proposed scheme.
