Privacy in transactive energy systems is challenging because protecting prosumer information can conflict with grid operator needs for system control. This work is innovative because it proposes privacy-preserving architectures that enable decentralized trading while allowing necessary system-level oversight without revealing individual transaction details.
This paper extends PETra with privacy-preserving mechanisms for IoT-based transactive energy systems using distributed ledgers. The work focuses on ensuring prosumer privacy while maintaining grid safety and security through anonymous trading, encrypted asset transfers, and auditable transactions. The paper provides detailed analysis of privacy and security requirements.
The paper demonstrates privacy-preserving energy transactions on distributed ledgers with mechanisms for anonymous asset transfer while maintaining grid safety constraints. Results show that prosumer privacy and grid stability are simultaneously achievable through cryptographic techniques and smart contract enforcement.

abstract = {Power grids are undergoing major changes due to rapid growth in renewable energy resources and improvements in battery technology. While these changes enhance sustainability and efficiency, they also create significant management challenges as the complexity of power systems increases. To tackle these challenges, decentralized Internet-of-Things (IoT) solutions are emerging, which arrange local communities into transactive microgrids. Within a transactive microgrid, {\textquotedblleft}prosumers{\textquotedblright} (i.e., consumers with energy generation and storage capabilities) can trade energy with each other, thereby smoothing the load on the main grid using local supply. It is hard, however, to provide security, safety, and privacy in a decentralized and transactive energy system. On the one hand, prosumers{\textquoteright} personal information must be protected from their trade partners and the system operator. On the other hand, the system must be protected from careless or malicious trading, which could destabilize the entire grid. This paper describes Privacypreserving Energy of cyb (PETra), which is a secure and safe solution for transactive microgrids that enables consumers to trade energy without sacrificing their privacy. PETra builds on distributed ledgers, such as blockchains, and provides anonymity for communication, bidding, and trading.},
