A Blockchain-Based Microgrid Trading Solution with Incentive Compatibility Mechanism

The emergence of microgrids has addressed a series of issues arising from energy supply diversity. Microgrid transactions typically exhibit characteristics such as peer-to-peer, high-frequency, and small-value. However, traditional centralized power trading platforms often struggle to rapidly respond to transaction requests and make efficient decisions. Therefore, a distributed and automated microgrid transaction scheme based on blockchain and incentive compatibility mechanisms is proposed. This scheme employs an incentive-compatible bilateral auction mechanism to induce users to make transaction bids based on their true valuations. Simultaneously, the scheme designs a sharded PBFT consensus algorithm optimization strategy and integrates a reputation mechanism to enhance the efficiency and security of the PBFT algorithm. Finally, simulation experiments are conducted on a 17-node blockchain network, confirming the effectiveness and practicality of the proposed solution.
