Research on key privacy protection technologies supporting flexible distributed resource layered aggregation transactions

In the "dual carbon" goal background, massive, dispersed, and ubiquitous distributed resources are becoming an important component of China's power system. However, distributed flexible resources faced with security issues, such as data loss, data tampering, and privacy breaches, during the process of participating in power trading by aggregation method. Therefore, this article proposes key privacy protection technologies to support flexible resource hierarchical aggregation transactions. Through fully analyzing the current situation of flexible resource hierarchical aggregation transaction and the existing privacy leakage problems, this paper designs a collaborative interaction process of flexible resource hierarchical aggregation transactions, and implements privacy protection for electricity enterprises participating in aggregation and benefit distribution in a trustworthy and autonomous manner.
