With the increasing proportion of prosumers possessing dual-source-load attributes, the establishment of an effective trading mechanism suitable for prosumers to incentivize energy consumption has become an urgent issue. To address this challenge, a cluster trading model based on blockchain technology for prosumers and operators is proposed, also the application of blockchain technology to prosumer electricity consumption behavior is quantified. Considering the independence of each entity within the cluster and the sequential nature of electricity price setting and quantity scheduling, Stackelberg game theory is employed to determine the optimal interaction strategy. Blockchain technology is used to update interaction information during this process. Simulation results demonstrate that establishing internal electricity pricing is able to enhance the photovoltaic self-consumption level within the cluster. Additionally, the aggregation and optimization of resources within the cluster can effectively improve the benefits of prosumers and operators by blockchain technology. Furthermore, in light of the PV on-grid tariff reduction policy, the effectiveness of the proposed model is validated.
