A Privacy-preserving Settlement Model for Power Transactions in Virtual Power Plants
Under the driving force of the"Peak Carbon Emissions and Carbon Neutrality"target,virtual power plants have gradually become an effective way to aggregate and control flexible resources in the power system and participate in power market transactions,achieving optimized allocation and rational utilization of distributed resources.However,when virtual power plant operators participate in electricity market transactions as market players,issues such as a lack of credibility in data collection and measurement,difficulty in privacy protection,and lack of transparency in benefit distribution still exist.Blockchain technology,with its decentralization and distributed storage features,aligns well with the autonomous decentralization of virtual power plants.To solve the above problems,a blockchain integration device is proposed to address the credibility issue of on-chain data from the source,and a profit distribution mechanism based on homomorphic encryption technology is designed to achieve verifiable privacy-preserving multi-party computation.Rigorous security proofs and simulation tests are conducted to demonstrate that the proposed solution achieves the goal of a transparent profit distribution mechanism while effectively protecting the privacy of all parties involved.
