Abstract
Modern power systems are transitioning from centralized generation to decentralized renewable architectures, introducing new operational and control challenges. Power grids face significant difficulties in integrating distributed energy resources (DERs), particularly heterogeneous generation sources. This paper proposes a blockchain-based energy market participation framework that integrates energy prosumers and consumers to efficiently address challenges such as bidirectional power flow, dynamic load balancing, and peer-to-peer energy exchange mechanisms. To build the proposed framework, Hyperledger Fabric (HF) is incorporated as a permissioned network among organizational entities such as energy producers, grid distribution operators, and regulatory bodies. The system manages various actors including renewable generators,non-renewable generators, battery storage systems, EV charging infrastructure, and advanced metering devices such as prosumers and consumers within the energy exchange system. The blockchain framework employs smart contracts to automate demand response while simultaneously tracking carbon emissions displacement. The proposed framework allows P2P trading to maintain the minimum renewable portfolio standards before trading non-renewable energy. The framework ensures security through X.509 authentication, TLS 1.3 encryption, SHA-256, and Raft-consensus.
