Peer-to-peer energy transaction matching mechanism balancing privacy-preserving ard result verifiability

Under the impetus of multi-bilateral economic dispatch, the peer-to-peer energy trading mode has gained significant attention. However, data privacy breaches and transaction regulatory challenges have emerged as critical barriers to its growth. A new peer-to-peer energy transaction matching mechanism named PV-RCI was proposed, which ensured the effectiveness of privacy-preserving mechanism and the validity of transaction matching mechanism. By incorporating a trusted auditing party and leveraging homomorphic encryption in conjunction with zero-knowledge proof, the proposed mechanism not only safeguarded data privacy but also ensured the verifiability of transaction matching outcomes. On the basis of promoting transaction matching between supply and demand parties, the proposed mechanism significantly reduced the overall social cost of transaction, offering a new approach to addressing privacy- preserving and regulatory issues in the energy trading sector.
