Transactive energy systems require careful attention to privacy while maintaining transparency and auditability of trades. This work is innovative because it provides a comprehensive framework addressing all three requirements simultaneously through blockchain-based architecture with cryptographic privacy mechanisms.
This paper presents PETra, a privacy-preserving platform for transactive energy systems using blockchain and cryptographic techniques. The work addresses security, safety, and privacy requirements for energy trading in microgrids, implementing mechanisms for anonymous trading, secure smart contracts, and distributed ledger transparency. The paper includes detailed description of asset structures and trading workflows.
The paper demonstrates PETra handling energy and financial asset transfers in a real microgrid system, achieving 90-percent trade closure within 23 seconds. The platform successfully implements anonymous address usage while maintaining immutable transaction records and enabling system operator oversight.

abstract = {Transactive energy systems (TES) are emerging as a transformative solution for the problems faced by distribution system operators due to an increase in the use of distributed energy resources and a rapid acceleration in renewable energy generation. These, on one hand, pose a decentralized power system controls problem, requiring strategic microgrid control to maintain stability for the community and for the utility. On the other hand, they require robust financial markets operating on distributed software platforms that preserve privacy. In this paper, we describe the implementation of a novel, blockchain-based transactive energy system. We outline the key requirements and motivation of this platform, describe the lessons learned, and provide a description of key architectural components of this system.},
