AES-based Privacy Protection strategy of virtual power plant under blockchain

As the energy structure shifts from fossil fuels to renewable energy, the energy industry is evolving towards decentralization and intelligence, with virtual power plants gradually gaining attention as a novel form of energy organization. However, virtual power plants still face significant challenges in data privacy protection when participating in electricity market transactions. To address the issue of privacy leakage, this paper proposes a privacy protection strategy for virtual power plants based on a blockchain integrated with the AES algorithm. Firstly, the AES algorithm is used to encrypt the transaction data information to ensure that the internal data of the virtual power plant is encrypted and protected during the calculation process. Second, the RBFT consensus algorithm is combined with blockchain technology for data storage and identity verification. Finally, through MATLAB simulations, the effectiveness of this algorithm in protecting privacy during transactions is demonstrated.
