Abstract

Blockchain has emerged as a promising solution for enhancing transparency and trust in peer-to-peer (P2P) energy trading. Due to the difficulty of handling optimization tasks on blockchain, existing studies usually clear the P2P market on blockchain without considering network constraints, then a central entity adjusts the trading results to guarantee the network security. However, an untrusted entity could manipulate the trading results in such an adjustment, which may undermine optimality and trust. This paper proposes a blockchain-based network-constrained P2P energy trading method for a reconfigurable distribution network. To address the challenges of handling optimization tasks, an on-chain and off-chain collaborative architecture is proposed to solve the network-constrained P2P energy trading model in a blockchain environment. A Proof-of-Mixed-Integer-Programming (PoMIP) consensus algorithm is proposed to ensure the transparency and trust of the P2P trading results. A fault-tolerant feasible region splitting method is embedded into the PoMIP algorithm to further improve the off-chain computational efficiency. Theoretical analysis and simulation results demonstrate the robustness and computational efficiency of the proposed method.
