Under the background of “carbon peak and carbon neutrality” proposed by China, the power market trading has flourished, and the capital has participated in the trading of distributed energy as an operator. In order to ensure that the data of users participating in the electricity market transaction has credibility, and lay a foundation for the development of the electricity market trading system and the issuance of green certificates, a trusted metering terminal for distributed power supply is proposed. By integrating lightweight acquisition, power optimization, data encryption, and blockchain technology, it provides secure data trust support for operators and distributed power users to participate in power market transactions.
