A power trading mode based on blockchain for prosumers

With the increase of penetration rate distributed generation on distribution network side, access a large number prosumers makes trading information massive, and demand for more flexible power mechanism is also strengthened. Therefore, weak-centralized mode based blockchain proposed in this paper. Trading automatically stored form smart contracts. The centralized organization only manages congestion does not participate process matching settlement. In security verification, successive over relaxation (SOR) iterative method improved paper, which improves efficiency convergence stability algorithm. Finally, case consisting six nodes presented to verify feasibility method.
